McIDAS, ldm-mcidas, Unidata-Wisconsin, Collaborations, and Cooperating Community Server Activities
May 14, 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 2003 released on August 6.
As of May 10, 2004 103 unique sites (out of 288
access records on the Unidata web portal) have downloaded Unidata
McIDAS 2003. For comparison, 105 sites have downloaded
- -X and -XCD addendum #1 was released November 4, addenda #2 released
February 20, addenda #3 released March 20, addenda #4 released
- incorporated latest SSEC development for support of decoded model
data in files with non-standard names
- Unidata Addendum contained code mods that enable users to use
- continuing support/bug fixes for Unidata and SSEC McIDAS-X, -XCD
- SSEC contacted us about sites downloading Unidata McIDAS who
were not allowed as per Unidata/SSEC agreements. The hole
in the Unidata web portal user registration that allowed access
to Unidata McIDAS by non-educational institutions was found and
plugged in April.
ldm-mcidas, Unidata-Wisconsin datastream, and NOAAPORT ingest
- ldm-mcidas: current release, v2003, announced on August 6
- Unidata-Wisconsin: increased broadcast frequency and number
of wavelength channels (bands) for
GOES-West IDD products. We are now sending all imager
channels in the IDD UNIWISC stream.
The datastream change was postponed from September to the beginning
of January because of site requests to not make the modifications
during the school year.
- spatial coverage of the GOES-East products increased to include
South America (when the satellite is providing those scans)
at the end of January/beginning of February
- NOAAPORT: developed NOAAPORT ingest system based on DVB-S
technology that the NWS is moving towards. Side-by-side ingest
comparisons of an existing Unidata NOAAPORT system with the new DVB-S
system showed that the new system operates with no loss of
data. We intend to create a web page describing our DVB-S development
so that universities can build their own NOAAPORT ingest systems
if they so choose (Yoksas, Chiswell, Schmidt, Smith).
- installed 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 cheaply 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 place.
- installed Unidata NOAAPORT ingest system at the Universidad de
Costa Rica in San Jose, CR at end of February. Now, and for
the first time the UCR is able to ingest, decode, and use
real time global observational data and NCEP and UKMET model
output for education and research.
Collaboration activities remain mostly unchanged since the May 2003 report.
Details can be found in May 1 Policy Committee Report.
NWS NEXRAD Level II Data Relay
- performed stress tests of LDM-6 to demonstrate capability of relaying
Level II data with negligible latencies
- participated in NWS Level II data distribution design planning
- on-site LDM training has been provided to NWS regional headquarters
The most active collaboration, even though it is being conducted in spare
time, is the MeteoForum initiative that is funded by UCAR Director's
Opportunity Fund (Jack Fellows). A
MeteoForum status report is include separately.
- continuing support of over 150 sites
- continuing participation by foreign universities and
institutions (McIDAS-X or LDM):
Argentina, Barbados, Brazil, China (Hong Kong), Costa Rica, France,
Portugal, United Kingdom, Jamaica, Mexico, Spain, Vietnam
(National Center for Hydro-Meteorological Forecasting),
Russia (Institute of Atmospheric Optics in Siberia), Thailand
- statistics for UPC support email can be found in a
Cooperating Community Data Servers - Prelude to THREDDS
Status unchanged since May 2003 report. Details can be seen in
May 1, 2003 Policy Committee Report.
