McIDAS, ldm-mcidas, Unidata-Wisconsin, Collaborations, and Cooperating Community Server Activities
March 28, 2005
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 (earliest release of Unidata McIDAS-X).
As of March 22, 2005 86 unique sites (out of 201
access records on the Unidata web portal) have downloaded Unidata
McIDAS 2004. For comparison, 105 sites have downloaded
three addenda have been released for v2004. The most recent release
upgraded the HDF package bundled with McIDAS-X to the latest
NCSA release to take advantage of support under 64-bit versions
of Linux. The updated included several other changes needed to
support builds under Fedora Core 3 64-bit Linux.
Highlights of the v2004 release include:
McIDAS is now fullly 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.

training workshop conducted on 26-30 October 2004.
ldm-mcidas, Unidata-Wisconsin datastream, and NOAAPORT and GOES ingest
ldm-mcidas: v2004 released on October 15, 2004
v2004 contains a bugfix for decoding Unidata-Wisconsin imagery
using McIDAS routing table naming facilities. The code 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.
Transition to auto selection of floater locations is to
be discussed separately in the User Committee Meeting agenda.
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 will be creating a web page describing our DVB-S
setup so that universities can build their own NOAAPORT
ingest systems if they so choose. (Chiswell, Schmidt, Yoksas)
installed a Unidata DVB-S 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 (Chiswell) on a low-powered (450 Mhz PIII
with 384 MB RAM) system running Fedora Core 3 32-bit Linux.
SSEC has adopted the Unidata DVB-S NOAAPORT ingest system for
licensed users of McIDAS-XCD.
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. SDI cards excessed by the Weather Underground will
be used as spare parts for this effort. 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 place.
NOAAPORT ingest system installed at the Universidad de Costa Rica in
San Jose, Costa Rica stopped functioning after failure of the satellite
dish's LNB. After the LNB gets replaced, the ingest will be
transitioned to use of the now-operational DVB-S broadcast.
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 is
a fairly high profile undertaking at the UCR, so its success
remains 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, IDV, McIDAS-X, LDM):
Argentina, Barbados, Brazil, China (Hong Kong), Costa Rica, France,
Jamaica, Mexico, Portugal, Russia, South Korea, Spain, Thailand, United Kingdom.

Cooperating Community Data Servers - Prelude to THREDDS
Texas A&M 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
