- This Executive Summary covers the six month period from November 1st 1999 to April 30 2000.
- The COMET Case Study Library has enjoyed large growth over this period
Subscribtion to the e-mail list has increased 25% from 77 to 97 entries
Cases ordered rose from 14 to 40
Data orders rose from 225 to 462
Volume of data nearly tripled from 3540 MB to 9020 MB
- Twenty Five (25) case studies are now available. All are
available for online search, browse, and FTP download.
- The last seven cases have been made available in AWIPS compatible netCDF format
- We have begun adding ACARS data to the case studies, with case 25 (Salt Lake City Tornado)
being the first case to implement ACARS data. ACARS data is made available in its native format (netCDF)
and is also available, decoded on-the-fly, in GEMPAK.
In the six months since the last Executive Summary, several
things have been accomplished involving both case study data
and building the community of users.
Data and Infrastructure
- Salt Lake City Tornado/Long Island Flash Flood, COMET Case 025, Aug 11-12, 1999, was announced to users and is available
with full online access through the CODIAC system.
This case was the first to include ACARS data.
This case is also available in netCDF AWIPS compatible format.
- Explosive East Coast Cyclogenesis, COMET Case 024, 19-26 Jan 2000, was announced to users and is available
with full online access through the CODIAC system.
This case is also available in netCDF AWIPS compatible format.
- Winter Severe Weather, COMET Case 023, Nov 08-11, 1998, was announced to users and is available
with full online access through the CODIAC system.
This case is also available in netCDF AWIPS compatible format.
- Northeast Severe Weather, COMET Case 022, 02-03 June 1998, was announced to users and is available
with full online access through the CODIAC system.
This case is also available in netCDF AWIPS compatible format.
- Wichita, Kansas Halloween Flood, COMET Case 021, 30 October-November 1 1998, was announced to users and
is available with full online access through the CODIAC system.
This case is also available in netCDF AWIPS compatible format.
Community Building
- Unidata will be holding a workshop June 19-22 discussing pedagogical issues.
The COMET Case study Library will be highlighted and implemented to display new pedagogy involving atmospheric data.
Artifacts of this workshop will be more exercises associated with the COMET Case Study Library.
- Elizabeth Page submitted an abstract, co-authored with Jeff Weber, Dolores Kiessling, and Patrick O'Reilly,
to the National Weather Association for conference in October 2000, titled "Significant Weather Events in the NWS/COMET Case
Study Library".
- Jeff Weber presented a paper co-authored with Elizabeth Page and Dolores Kiessling:
"COMET Case Study Library Into the New Millenium" at the 2000 AMS IIPS Unidata special session in Long Beach.
- Elizabeth Page and Unidata are continuing to work with the NCDC to establish an archive of NOAAPORT data to support case study development in the AWIPS era.
Our case study usage statistics (subscribers to the
casestudies e-mail list, tape requests, data downloads,
and web hits) continue to increase. For details on all the current usage statistics, see the
Detailed Statistics page.
Statistics and current plots of web hits , data downloaded, and the "new" data ordered are also available on the
Case Studies Usage Statistics Page.
Development of more case studies continues, giving us more
case studies to load into the CODIAC system. Future cases
include:
- Case 26: Pacific Northwest Winter Storm (November 23-26, 1999)
- Case 27: Southern Louisiana Tornados (January 1-2, 1999)
See the
Case Study Status page
We will continue our efforts to make the case
studies easier to access and use by the user community. These
efforts will include keeping our web site up to date and
helping with enhancements to the CODIAC system (i.e. ACARS decoders).
In our continuing efforts to expand the community, we will continue to give presentations
and publish papers on this project. The next conference to be attended is the NWA
We are tracking the data format issues arising from the NWS
modernization efforts. We have implemented AWIPS compatible
netCDF format so that all future cases can be downloaded in raw data formats,
GEMPAK formats, or AWIPS formats.
