McIDAS, ldm-mcidas, IDD Datastreams, Collaborations, and Cooperating Community Server Activities
September 11, 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 2005 released on July 25.
As of September 7, 2005 21 unique sites (out of 94
access records on the Unidata web portal) have downloaded Unidata
McIDAS 2005. For comparison, 102 unique sites have downloaded
six minor updates have been released for v2005.
Highlights of the v2005 release include:
McIDAS now uses gzip-compressed data transfers from remote
ADDE servers to McIDAS-X client workstations by default.
Remote server workstations must have port 112 open to allow
clients running McIDAS-X 2005 to access their data. Ports
500 and 503 must also be open to clients to access data from
ADDE servers running McIDAS-X releases prior to v2004.
v2005 includes Meteosat Second Generation (MSG) client and
server updates to allow copying (with the IMGCOPY command)
of selected MSG bands (not just one band or all bands). This
feature works only if both the server and client are running
version 2004a or later.
Several enhancements to the SSEC GUI and the beginnings of an
overhaul of the Unidata MCGUI.
Unidata supports both 32-bit and 64-bit versions of Fedora
Core 3 and 4 Linux (although XCD has not been extensively
tested on 64-bit Fedora Core 4).
Configuring the mcidas account and XCD setup has
been simplified through the inclusion of setup scripts.
The McIDAS distribution tar file is now compressed using
gzip. This requires that the user have gunzip to uncompress
the distribution. Switching from compress to gzip reduced
the distribution file from 72 MB to just under 50 MB.

training workshop conducted on July 31 - August 4, 2005 at the
UPC offices in Boulder.
ldm-mcidas, IDD datastreams, and NOAAPORT and GOES ingest
In response to a user request, hourly-summary and six-minute RASS
data was added to the FSL2 datastream in August. (Yoksas, Miller)
ldm-mcidas: v2004 was released on October 15, 2004
Decoding support for the FSL2 RASS data will be added for the
v2005 release in October/November. (Yoksas)
Unidata-Wisconsin: IDD UNIWISC datastream continues to
supply Unidata users with realtime GOES data.
NOAAPORT: The Unidata-developed DVB-S NOAAPORT ingest system
has been in use at the UPC and several (7) Unidata sites since the
NWS transition to DVB-S broadcast. (Chiswell, Schmidt, Yoksas)
Notably, the Unidata DVB-S NOAAPORT ingest system installed at
the Southern Region Climate Center (SRCC) at Louisiana State
University (LSU) worked well throughout hurricane Katrina.
SSEC provides and supports the Unidata DVB-S NOAAPORT ingest system
for its licensed users of McIDAS-XCD.
The SSEC-developed NOAAPORT desktop ingest system (SDI) that
had been used by the SRCC was being repurposed at the UPC into a
GOES-West ingester and ADDE image server for the Unidata community.
SDI cards donated to the UPC by the Weather Underground and St. Louis
University will be used to establish a GOES-East ingester in UCAR
and as spare parts.
Full resolution GOES-East/West imagery are also available
via ADDE from a Unidata-owned, toplevel IDD relay node housed
in the SSEC data center. As soon as both Unidata GOES-West and
GOES-East systems are operational (sometime late this fall),
their availability will be announced to the community (Yoksas,
the NOAAPORT ingest system installed at the Universidad de Costa
Rica in San Jose, Costa Rica stopped functioning after an apparent
failure of the satellite dish's LNB. Recent troubleshooting by
UCR personnel (Marcial Garbanzo) showed that the likely cause of
the outage was oxidation in connectors in the signal path. After
installing new connectors, the system returned to functionality for
a week only to then fail with an LNB fault.
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.
Collaborations with EUMETSAT aimed at promoting use of remote access
methodologies (first ADDE and then full THREDDS), first in
Darmstadt and then in member states, continue at a low level.
The eventual goal is to encourage EUMETSAT to make realtime
Meteosat data available for research and educational use through
INPE/CPTEC is attempting to develop methods to convert satellite
imagery in TeraScan (tm) format to McIDAS AREA format and eventually
to provide remote access to those data through THREDDS servers.
MeteoForum. This collaboration has resulted in the creation in a
South American extension of the IDD, the IDD-Brazil/b>.
This effort 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,
Argentina, Barbados, Brazil, Chile, 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
Publically Accessible McIDAS ADDE servers.
