McIDAS, ldm-mcidas, Unidata-Wisconsin, Collaborations, and Cooperating Community Server Activities
September 20, 2004
Efforts referenced within this report are based on five of the six
endeavors articulated in the Unidata 2008 Proposal:
Endeavor 1: Responding to a broader and more diverse community
Endeavor 2: Comprehensive Support Services
Endeavor 4: Software to analyze and visualize geoscience data
Endeavor 5: Distributed, organized collections of digital material
Endeavor 6: Improved data access infrastructure
Unidata McIDAS-X, -XCD
Version 2004 released on July 21 (this is the earliest release of
As of September 20, 2004 45 unique sites (out of 117
access records on the Unidata web portal) have downloaded Unidata
McIDAS 2004. For comparison, 105 sites have downloaded
Some highlights of the v2004 release include:
McIDAS is now full supported on the MacOS-X (Darwin) operating system.
McIDAS-XCD requires some entry point name changes (MacOS-X treats
entry point names case insensitively).
Unidata now supports McIDAS on Windows XP (using Microsoft Services
McIDAS now has the ability to use gzip compression during transfers
of data from ADDE remote servers to McIDAS-X client workstations.
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
the type of data transfer can now be specified on a per-application
basis by specifying the MCC= keyword on the command line.
McIDAS can now produce GeoTIFF format output
there are new ADDE servers for AIRS (Aqua satellite) data
there are numerous enhancements to the SSEC GUI
support for building with gcc/f2c/mcfc was dropped. Sites now use
the gcc/g77 compiler combination instead.
Unidata McIDAS is now supported on RedHat Fedora Core 1 & 2 Linux. SSEC
supports McIDAS on RedHat Enterprise WS 3.0 Linux.
updated Unidata McIDAS website to use same look-and-feel as other
-X and -XCD Addendum #1 scheduled for released in mid-October
incorporate latest SSEC development for support of decoded model
data in files with non-standard names

ldm-mcidas, Unidata-Wisconsin datastream, and NOAAPORT ingest
ldm-mcidas: current release, v2003, announced on August 6, 2003
Next release, v2004, will be released at the end of September/early October.
v2004 contains a fix for a bug in decoding Unidata-Wisconsin imagery
using McIDAS routing table naming facilities. The bug was not truncating
images that were being overwritten. The effect of the bug was the
file sizes decoded using McIDAS routing table naming facilities were
larger than those not using the routing table naming facilities.
Unidata-Wisconsin: We continue to send all imager
channels in the IDD UNIWISC stream.
The spatial coverage of the GOES-East products includes all of
South America whenever the satellite is providing those scans.
Increased disk space requirement
is evidentally not an issue for UNIWISC users since we have received
no inquiries regarding the change.
NOAAPORT: We developed a NOAAPORT ingest system based on the DVB-S
technology that the NWS will move to at the beginning of February, 2005.
We are considering creating a web page describing our DVB-S
development so that universities can build their own NOAAPORT
ingest systems if they so choose. Our NOAAPORT ingest system
will not be a supported product.

installated a Unidata NOAAPORT ingest system at
the Southern Region Climate Center (SRCC) at Louisiana State
University (LSU). This system was put together from software
developed at the UPC (Schmidt, Chiswell, Yoksas) and hardware
bought on Ebay (Schmidt).
The SSEC-developed NOAAPORT
desktop ingest system (SDI) that had been used by the SRCC is
being repurposed at the UPC into a GOES ingester. The SRCC SDI
will be coupled with an SDI already in the UPC's possession to
provide remote ADDE access to full GOES imager and sounder data
for the Unidata community. A twin to this system has been in
operation at the SSEC for over a year, but announcement of its
existence has been delayed until this needed redundancy is in
NOAAPORT ingest system installed at the Universidad de Costa Rica in
San Jose, Costa Rica (February) has been functioning well for the
past two months. Previously, the system suffered occasional ingest
lockups that were traced down to the use of LiS software under
SMP Linux (Fedora Core 1) kernels. The same system running under
a single processor kernel shows none of the problems encountered
when run with dual processors.
The UCR system was put together from excessed computer equipment
at UCAR, monies awarded to UCR PI Vilma Castro through a WMO VCP
proposal (funded by the US and Canadian National Weather
Services), and existing equipment at the UCR (7 meter satellite
dish and associated electronics and cabling).
This NOAAPORT reception system installation remains
a fairly high profile undertaking at the UCR, so its success
was important for Unidata and MeteoForum.
MeteoForum. This collaboration
has resulted in the creation in a South American extension of the
IDD. This effort, called the IDD-Brazil, has captured the
interest in the highest levels in Brazilian meteorological circles. More
information on the IDD-Brazil can be found in the
MeteoForum status report.
continuing support of over 150 sites
continuing participation by foreign universities (GEMPAK, McIDAS-X, LDM):
Argentina, Barbados, Brazil, China (Hong Kong), Costa Rica, France,
Jamaica, Mexico, Portugal, Russia (Moscow State
University), South Korea, Spain, Thailand, United Kingdom.
Cooperating Community Data Servers - Prelude to THREDDS
Texas A&M has very recently joined the cooperating community
server effort by opening access to a machine that keeps 30 days of both
Level II and Level III NEXRAD data online. The list of cooperating
community servers and the datasets that they make available can be seen
