Unidata McIDAS-X - v2004 Release Notes

Before Installing McIDAS-X

Complete all Required Actions below.

Core Software Changes

Review the changes to core software before installing McIDAS-X 2004. McIDAS-X Significant Changes lists some of the significant changes since the last upgrade. Two ASCII text files, MAY04PRG.TXT and MAY04INQ.TXT, list all software changes made to McIDAS-X since the previous upgrade. A third file, MAY04OPN.TXT, lists all software bugs known at the time this upgrade was distributed.

Required Action:

See McIDAS-X Significant Changes of this document to review the significant changes made to core software.

Operating System and Compiler Changes

Beginning with this upgrade, the following changes were made to operating system and compiler versions that McIDAS-X is supported on.

• Apple Mac OS X was added as a new operating system that McIDAS-X is supported on.

• Microsoft Windows XP with Services for Unix 3.5 (requires 3.5; version 3.0 will not work) replaced Windows NT with Interix 2.2 as the Windows-based operating system that McIDAS-X is supported on. The only significant change in going from NT to XP is that McIDAS-X ADDE remote server (installed separately with the mcinet2004.sh script) is available for the first time on Windows-based systems. (The remote server was not available in the NT package.)

• SSEC supports RedHat Linux Enterprise WS 3.0; Unidata supports RedHat Fedora Core 1. We believe that the distribution will work on a variety of Linux distributions, but we have no way of testing this.

• The vendor and non-vendor (GNU) compiler versions that McIDAS-X builds are supported on were changed for all platforms. The most significant change is that support of McIDAS-X builds using non-vendor compilers was switched from f2c/gcc to g77/gcc. The switch from f2c to g77 as the Fortran compiler was done mainly because it's part of the GNU compiler package. The McIDAS-X 2004

Compatibility with -X Remote Servers and -XCD

McIDAS-X 2004 can run in a stand-alone mode. However, many commands can access data on other workstations (remote servers). Therefore, your McIDAS-X client workstations and the remote servers they access must be running compatible versions in order for all features to work as expected.

For example, use of the three items below is dependent upon the McIDAS-X version that the client and/or server is running.

• Remote server workstations must have port 112 open to allow clients running McIDAS-X 2004 to access their data. Likewise, ports 500 and 503 must also be open to allow clients running McIDAS-X 2003 to access their data. See ADDE Data Transfer Methods elsewhere in this document for details.

• In versions prior to this 2004 upgrade, ADDE remote servers (installed separately with the mcinet2004.sh script) were not available in the Windows-based version of McIDAS-X. That has changed in this upgrade, as McIDAS-X for XP (which can be configured as a remote server) replaced McIDAS-X for NT as the Windows-based version of McIDAS-X.

• This upgrade contains many server and client modifications to work with AIRS data from the Aqua satellite. In order to use AIRS data, including the new WL and WN keywords in the IMG* commands, both the client and server must be running version 2004.

Coordinate upgrading your site's McIDAS-X and -XCD systems according to your needs, considering the compatibility requirements listed above.

Deleted Command

The FOUSRPT command was deleted from McIDAS-X beginning with this upgrade. It was deleted because its functionality is available in the command MOSRPT (which was added in version 2003, and can list ETA and GFS, as well as NGM, MOS forecasts).

Required Action:

Change all occurrences of FOUSRPT to MOSRPT in your scripts, macros, BATCH files, F-Key Menus, McBASI programs, and SKE entries.

Disk Space

McIDAS-X disk space requirements increased, mainly due to the addition of new servers.

The overall disk space requirements for obtaining, building and installing McIDAS-X 2004 are listed in the table below. The disk space requirements for 2003 are listed for comparison. The compiler type (vendor or gcc/g77) used for each build are also listed.

Operating system	Compilers	McIDAS-X 2003	McIDAS-X 2004
AIX 5L version 5.1	vendor	345 MB	395 MB
Fedora Core 1 Linux	gcc/g77	320 MB	328 MB
FeeBSD 4.[89]	gcc/g77	320 MB	328 MB

McIDAS-X Significant Changes

Complete all Required Actions below. Optional Actions are only for your consideration.

ADDE Data Transfer Methods

In McIDAS-X versions 2003 and later, you can request data from ADDE remote servers using three different transfer methods. The methods are gzip- compressed, compressed, and uncompressed.

The default method is determined by the MCCOMPRESS environment variable. In this upgrade, a new global keyword that overrides the environment variable was added. The new global keyword is named MCCOMPRESS=, which can also be specified as MCC=. For example, IMGDISP GOES/EAST 5 BAND=4 STA=KATL MCC=GZIP overrides the environment variable setting and requests that the remote server use gzip to compress the specified image data, then send it to your workstation, which uses gunzip to uncompress it then displays it in frame 5.

In McIDAS-X 2003, requests for gzip-compressed data are sent to server port 112, compressed to server port 503, and uncompressed to server port 500. Beginning with this upgrade, all requests, regardless of the data transfer method, are sent to server port 112. In all cases, after receiving the client's request, the remote server gathers the requested data and uses the appropriate compression method to package the data, then sends it to the client through the same port.

Important Notes:

1. The gzip-compressed and compressed methods are usually best for transferring large data files over slow data connections. The uncompressed method minimizes overhead and therefore is usually the best method to use if the remote servers you access are on a network with fast data transfer rates.

2. Sites with firewalls or other screening mechanisms must open port 112 on their remote servers if they want to allow clients running McIDAS-X 2004 to access their data. Likewise, ports 500 and 503 must also be open to allow clients running McIDAS-X 2003 to access their data.

Required Action:

Users who want to choose between the three data transfer methods must read and complete the instructions in the Using Compressed Data Transfers section of the McIDAS User's Guide.

After installing McIDAS-X 2004 on their ADDE remote servers, administrators must install the McIDAS-X 2004 ADDE remote server (using the mcinet2004.sh script). This step is required because the script was modified to work better with newer versions of xinetd. See Installing the McIDAS-X 2004 ADDE Remote Server and Updating Clients to Use Compressed Data Transfers in the Unidata McIDAS User's Guide for more information and the installation instructions.

McIDAS-X GUI

The McIDAS-X GUI was modified to include the changes listed below.

• The main window's toolbars were rearranged to more logical groupings, and a View menu was added to let you hide a toolbar, or move it to the top or bottom of the window.

• A new Time Scheduler GUI was added under the main window's Configure menu.

• A new Command History GUI that shows McIDAS commands that were entered through the command line or run through the GUI was added under the main window's List menu. The Command History GUI allows searching of previously-run commands, then puts them in a buffer to edit and re-run. The number of commands in the Command History GUI is equal to the value set in the -ih flag in the $HOME/.mcidasrc file.

• The Brit and Temp monitors on the main window were updated to do a better job of reporting the correct values.

• The latitude/longitude display on the main window was changed from using +/- to N/S/E/W to indicate hemisphere.

• Right-click menus were added to the Graphics On/Off Toggle and Graphics Erase buttons on the main window that allow you to select individual graphics colors to toggle on/off or erase.

Use the GUI by starting it with the GUI command, selecting the Start GUI upon McIDAS startup option in the mcidas -config GUI, or automatically start the GUI with each McIDAS-X session by adding a -c GUI command in the Run commands at startup section of your .mcidasrc file.

PRDUTIL Command

The PRDUTIL command was modified to use the IMGLIST command to generate its output, instead of using an internal version. It was also modified to no longer allow its file specification as an area number (i.e., you must specify an ADDE dataset name and position number instead of an area number).

Required Action:

Check all occurrences of PRDUTIL commands in your macros, scripts, BATCH files, F Key Menus, McBASI programs and SKE entries to see if they specify an area number in the file/dataset parameter. If any do, change their area number to an ADDE dataset name and position number that maps to that area number. For example, if you have a local dataset named LOCAL/AREAS that is mapped to areas 1-9999 and you have a script that runs command PRDUTIL LIST 1250, change the command to PRDUTIL LIST LOCAL/AREAS.1250.

AXFORM Command

The AXFORM command was modified to left- or right- justify the values in its HDR output file. Therefore, values in fields like Band, Lines and Elements are usually in different columns than in previous versions.

Required Action:

Check your scripts to see if they read HDR files and parse their values. If so, modify the column offsets to those used in the HDR files generated by the McIDAS-X 2004 version of AXFORM.

Other Modifications

The modifications below require no special action.

Command / Topic	Modification
FRMSAVE	fixed to save what you see on the display; so if the image or graphics is toggled off (with K or W commands) it will not be included in the file created with FRMSAVE
GEO	added DAY and TIME keywords to select an earlier image
LWCON	added FLIP keyword to control when words containing ASCII text are byte flipped
LWU	added bword and eword parameters to COPY option to specify a range of words to copy from the source file
MAP	added options to the LABEL keyword to choose the latitude and longitude label formats, and added LLMARK keyword to draw reference symbols (e.g., plus signs (+)) at the specified latitude and longitude intervals
NAVCALC	added IMC keyword to choose whether to list the actual GVAR (GOES-8 and later) satellite subpoint, or that corrected by the Image Motion Compensator
PTDISP, RAOBPLOT, SFCPLOT	updated COLOR keyword to allow choice of plot color based on parameter value; for example, SFCPLOT T USA COLOR=2[50-89B10] plots 50-59°F temperatures in graphics color level 2, 60-69°F in level 3, 70-79°F in level 4 and 80-89°F in level 5; temperatures less than 50°F are in level 1, and temperatures greater than 89°F are in level 6
PTLIST	added DM and DMS options to FORMAT keyword to list latitude and longitude values in degrees:minutes and degrees:minutes:seconds, respectively; the default format for latitude and longitude values is decimal (which can be altered with the keyword's F option)
SFCCON, SFCPLOT	modified the equations that calculate station pressure to, by default, use altimeter setting instead of sea-level pressure; this affects the PSTN, MIX, THA and THAE options because they are calculated using station pressure
ZA	replaced the L, C and R options in the justify parameter with new options that allow vertical, as well as horizontal, positioning; the new options are LA, LC, LB, CA, CC, CB, RA, RC and RB, where L means left, C means center, R means right, A means above and B means below the center of the cursor; to retain backward compatibility, entering L, C or R for the 'justify' parameter will work the same as it did in previous versions
WL and WN Keywords	added WL and WN keywords to IMGCOPY, IMGDISP, IMGFILT, IMGLIST, IMGPROBE and IMGREMAP commands that allow you to select Aqua AIRS data based on wavelength and wave number
WMO Weather Symbol Fonts	updated GRDDISP, PTDISTP, SFCMG and SFCPLOT commands to use the new WMO weather symbol fonts listed in the Data Files section; the most significant change is that the calm wind symbol plotted with commands like SFCPLOT WINDB or PTDISP PAR=WIND FORMAT=VECT has been changed from a plus sign (+) to a small bullseye (two concentric circles)
AIRS HDF Servers	added AIRS HDF servers to McIDAS-X to allow creation of datasets containing AIRS data in HDF format on local and remote servers, and display or manipulation of the data using the IMG* commands; see the DSSERVE command's online help or its documentation in the McIDAS User's Guide (revised 5/04) for information about creating the datasets
GeoTIFF Servers	added GeoTIFF servers to McIDAS-X to allow creation of GeoTIFF files with the IMGCOPY, IMGFILT, IMGOPER or IMGREMAP commands; see the DSSERVE command's online help or its documentation in the McIDAS User's Guide (revised 5/04) for information about creating the datasets
MODIS HDF Servers	updated to allow use of files with names that follow the MODIS Direct Broadcast file naming conventions, as well as those that follow the Goddard DAAC file naming conventions
netCDF Image Server	modified to allow use of the DIRFILE keyword in the DSSERVE command for determining where to write newly-created files
POES Level 1b Servers	added option to use the SAA Level 1b file's line-by-line lat/lon navigation (rather than the orbital navigation at the beginning of the file) by specifying INFO=LALO in the DSSERVE command; also added new servers to write POES/NOAA KLM AVHRR area data to SAA Level 1b file format; see the DSSERVE command's online help or its documentation in the McIDAS User's Guide (revised 5/04) for more information

Data Files

The following changes were made to files in the ~mcidas/data directory.

File name	Change
AIRSBAND.DOC	new text file containing information about each of the 2378 bands (channels) in AIRS data
AIRSBANDINFO	new binary file created from AIRSBAND.DOC that the AIRS server uses to map wavelength and wave number to band number
CORE.SAT	changed MSG-1, MSG-2 and MSG-3 entries to Meteosat-8, Meteosat-9 and Meteosat-10
DCETAMOS	increased number of rows from 38 to 42 and number of columns from 350 to 2000; added category FW (for "few") to CLD field; added seven new fields (CIG, OBV, POS, POZ, SNW, TYP, VIS)
DCGFSMOS	increased number of rows from 38 to 42 and number of columns from 350 to 2000; added category FW (for "few") to CLD field; added new field SNW
DCISFC	increased number of columns from 3500 to 7000
MAP.CORE	added new global keyword LLMARK to draw reference symbols, e.g., plus signs (+), at the specified latitude and longitude intervals; the global default value is set to NO
netcdfgrid.cfg	added new comments to make it more informative
netcdfbuoy.nc	new sample netCDF point file containing buoy data; netcdfpoint.cfg is a sample configuration file for this type of data
OUTLHRES	updated to remove an extra line that was extending off the Ross Ice Shelf in Antarctica
SATANNOT	changed sensor source numbers 51, 52 and 53 from MSG-1, MSG-2 and MSG-3 to Meteosat-8, Meteosat-9 and Meteosat-10
SATBAND	added band information for AIRS (2378 channels) and reordered MSG bands to match Eumetsat's ascending-wavelength order
SFCPLOT.CORE	changed the format of VIS plots from F4.1 to F5.1 to accommodate triple-digit visibilities
STNDB.CORE	updated to contain state codes for countries other than the United States (e.g., BC for stations in British Columbia, Canada); changed state field from CA to TX for station KBYY (Bay City, Texas); updated lists of ETA MOS and GFS MOS stations
USCOUNTY.MAP, USZONE.MAP	updated to most recent versions as of 14 April 2004
WXSYM.FFD, wxsymr*.bdf	updated WMO weather symbol font package so there is consistency across all sizes

Required Action:

Merge these modifications with all local copies of the data files.

Local Code

Compile and link all local code after installing the upgrade. Listed below are some of the software and structural changes most likely to affect your local code.

• The updates listed below were made to allow use of Meteosat-8 data.

  • added a new server to read/access real-time segmented Meteosat Second Generation Level 1.5 files transmitted by EUMETSAT

  • updated calibration and navigation routines kbxmsg.dlm and nvxmsg.dlm

  • included new band number and wavelength values in SATBAND and SATANNOT files

  • updated image (client) commands and local area servers

• The type 5 area was created for use with high spectral data. The type 5 area has the same format as type 4 (current area format), but handles bands differently. In type 4, two words in the area directory are bit-mapped to designate up to 64 bands and the level section on each line indicates which bands are present on each line. Type 4 allows you to store any combination and order of bands. In type 5, the two directory words indicate the beginning and ending band number. All bands must be present on every line; therefore the levels section is not used. Many routines were updated to accommodate the large number of bands found with Aqua AIRS data, including those listed below.

  • added a new server to read/access AIRS data

  • added new modules m0wltoband.for and m0wntoband.for to map wavelengths and wave numbers to McIDAS band numbers

  • updated image commands and area servers to accommodate large band numbers

  • increased areaparm.inc variables MAX_BAND and MAX_AUX_SIZE to 3000 and 2000000, respectively.

• The updates listed below were made to client/server communications.

  • all 2004 client requests will be sent through port 112 (regardless of compression type)

  • all servers MUST have port 112 open to send data to 2004 clients

  • 2004 client commands can override the default compression type set in the MCCOMPRESS environment variable by using the new global keyword MCCOMPRESS; the keyword accepts values of NONE, GZIP and COMPRESS

  • the MCCOMPRESS global keyword was added to m0arg.h

• Version 2004 is the first release of McIDAS-X running under Mac OS X. Many changes were required to comply with Mac OS standards.

• The ADDE remote server installation script, mcinet.sh, was updated for newer versions of xinetd.

• The following modules were updated to allow successful builds of McIDAS-X with vendor compilers on Solaris 9 workstations.

  makefile	mccomp.sh	mcinst.sh
  m0util.c	mct_winc.c	mct_winx.c

• Obsolete routines gunrvl.for, gunrv2.for and import.pgm were removed.

• Module daytime.c was updated to compute the number of seconds since 1970 without using Unix system calls.

• The length of filenames allowed in the DSSERVE command's DIRFILE keyword was increased to the value of MAXPATHLENGTH.

• The FLIP keyword was added to the LWCON command to determine if words containing ASCII text are flipped.

• The default Fortran compiler for non-vendor (GNU) builds was changed from f2c to g77. f2c is no longer supported.

• All references to specific heat and freezing point of water constants are now defined in McConstants.inc and added to mcidas.h.

• The SFCPLOT and SFCCON commands now default to altimeter setting to calculate station pressure for deriving PSTN, MIX, THA and THAE.

• The mcgget_ prototype was corrected in mcidas.h.

McIDAS-XCD Compatibility with McIDAS-X

Required Action:

Coordinate upgrading your site's McIDAS-X and -XCD systems according to your needs. In particular, see Compatibility with -X Remote Servers and -XCD for items that may impact your decision on when to upgrade to -XCD 2004.

Installing McIDAS-XCD

If you need assistance with the upgrade send email to <support@unidata.ucar.edu>.

Required Action:

Obtain and install McIDAS-XCD 2004 using the instructions in the Unidata McIDAS-X Users Guide.

McIDAS-XCD Changes

This section lists the changes made to McIDAS-XCD since the last upgrade (version 2003) and the Required and Optional actions to perform immediately after installing McIDAS-XCD 2004.

SAO/METAR Stations

The total number of SAO/METAR stations has increased beyond the prior maximum limit of 6500. Complete the required actions below to increase the maximum number of SAO/METAR stations to 7000.

Required Actions:

Complete the four steps below prior to starting -XCD.

1. Login to the McIDAS-XCD workstation as user mcidas.

2. Edit the configuration file ~mcidas/workdata/ISFCDEC.CFG and change its value for NCOLS from 6500 to 7000.

3. Start a McIDAS session.

4. Rebuild the rapid access pointer file for surface data.
   Type: BILDTEXT INIT SAOMETAR.RAP SAOMETAR.RAT 7000 4 C4 36 1 80 SAOMETAR X 48
   
   
Note: This will delete your existing SAO/METAR rapid access text and pointer files. A new rapid access pointer file will be generated upon running BILDTEXT and a new rapid access text file will be generated when new data is ingested.

GFS Grid Labeling

The following actions need to be completed.

Required Actions:

1. Change the real-time grid configuration file so that all GFS (formerly AVN/MRF) grids will be filed into the same grid file range.
   1. Edit the file ~mcidas/data/RTMODELS.CFG

   2. Delete or comment out the line beginning with MRF=

   3. Change the line that begins with AVN= so that it begins with GFS=

   4. Save and close the file

2. Login as user mcadde and create a dataset named RTGRIDS/GFS.

   Note: This procedure will retain the old datasets (RTGRIDS/AVN and RTGRIDS/MRF) so that your users will not have to switch to the new dataset (RTGRIDS/GFS) immediately. When all of your users have switched to the new dataset you may delete the old ones.

   1. Edit the file ~mcidas/workdata/RESOLV.SRV

   2. Copy the line that begins with N1=RTGRIDS,N2=AVN and paste it directly beneath the original line

   3. In the line you just added, change N2=AVN to N2=GFS

   4. Find the line that begins with N1=RTGRIDS,N2=MRF and change the grid file range to that of the new line containing N2=GFS

      The resulting lines should be similar to these:

      N1=RTGRIDS,N2=MRF,TYPE=GRID,RT=Y,K=GRID,R1=5701,R2=5900,C=Real-Time MRF Grids,
      N1=RTGRIDS,N2=AVN,TYPE=GRID,RT=Y,K=GRID,R1=5701,R2=5900,C=Real-Time AVN Grids,
      N1=RTGRIDS,N2=GFS,TYPE=GRID,RT=Y,K=GRID,R1=5701,R2=5900,C=Real-Time GFS Grids,
      

      Note that all three of these datasets point to the same grid file range.

   5. Save and close the file.

GFS MOS Stations and Fields

The following actions need to be completed.

Required Actions:

1. Start a McIDAS-X session under the mcidas account, then register the new GFS MOS MD file schema.
   Type: SCHE DCGFSMOS

2. Run the command below from a McIDAS-X session under the mcidas account to delete files GFSMOS.RAP and GFSMOS.RAT and create a new GFSMOS.RAP file. The new GFSMOS.RAT file will be created as soon as the next GFS MOS message is received.
   Type: BILDTEXT INIT GFSMOS.RAP GFSMOS.RAT 2000 2 C4 2 12 80 GFSMOS X 48

3. Edit the file ~mcidas/workdata/GFSMOS.CFG and change the value for NCOLS to 2000 and the value for NROWS to 42. This change increases the maximum number of GFS MOS stations that can be written to the GFS MOS MD file and increases number of forecast periods.

4. Delete or move the current day's GFS MOS MD file. You must do this because the updated GFS MOS decoder will try to write to the MD file using the updated schema, which contains the new Snowfall Amount (SNW) field. MD files that were created using the previous version of the schema do not contain this field.

ETA MOS Stations and Fields

The following actions need to be completed.

Required Actions:

1. The ETA MOS configuration file must be updated so that data from new ETA MOS stations will be decoded. To do so, edit the file ~mcidas/workdata/ETAMOS.CFG and make the following changes.
   1. Locate the line WMO=FOUS and change it to WMO=FOUS FOAK FOPA

   2. Locate the next line MINPRD 44 and change it to MINPRD 44 47 40

   3. Locate the next line MAXPRD 49 and change it to MAXPRD 49 49 40

   4. Locate the line NROWS=38 and change it to NROWS=42

   5. Locate the line NCOLS=1400 and change it to NCOLS=2000

2. Start a McIDAS-X session under the mcidas account, then register the new ETA MOS MD file schema.
   Type: SCHE DCETAMOS

3. Run the command below from a McIDAS-X session under the mcidas account to delete files ETAMOS.RAP and ETAMOS.RAT and create a new ETAMOS.RAP file. The new ETAMOS.RAT file will be created as soon as the next ETA MOS message is recieved.
   Type: BILDTEXT INIT ETAMOS.RAP ETAMOS.RAT 2000 2 C4 2 12 80 ETAMOS X 48

4. Delete or move the current day's ETA MOS MD file. You must do this because the updated ETA MOS decoder will try to write to the MD file using the updated schema, which contains the seven new fields. MD files that were created using the previous version of the schema do not contain those new fields. (Note: You can determine the file range for your ETA MOS MD files by the value for MDF in ETAMOS.CFG.)

RTGRIDS Default Dataset Configuration

A new optional dataset naming configuration for real-time grids is included in this upgrade.

Optional Action:

Switch to the use of RTMODELS.CFG.2004 (located in ~mcidas/mcidas2004/data) in place of RTMODELS.CFG if you want to implement its dataset names and file locations. Installing it is optional because sites are free to choose their own dataset names and file locations.
