COMET Case Studies Status Report: October 2001
Prepared by Jeff Weber
There are now thirty-eight (38)
COMET case studies available
- Recent Additions to the Library
- Case 33: Missouri Isolated Severe Weather 20-22 May, 2000
- Case 34: New Jersey Flood: Terrain-Locked Convection 11-13 August, 2000
- Case 35: San Antonio Flood 16-19 October, 1998
- Case 36: Seattle Snowstorm 15-17 February, 2001
- Case 37: Tropical Storm Allison 05-06 June, 2001 (In Process)
- Case 38: Birmingham Tornado 07-09 April, 1998
- Case 39: Iowa Bow Echo 29-30 June, 1998
- Casestudies 19-39 are now available in netCDF as well as the standard GRIB, GEMPAK, NIDS, and MCIDAS formats. Future cases will continue to be made available in netCDF as well as the existing formats.
- Case 25 began the implementation of ACARS data in to the datasets, with decoding available on-the-fly from netCDF to GEMPAK.
All casestudy events after May 1999 (the beginning of the JOSS archive) will eventually include ACARS data.
- COMET Case Study Library has been reactive to significant weather events and modified publishing schedule to address these data demands. The latest example being Tropical Storm Allison of 05-06 Jume 2001, to be released at the end of October.
- We continue to investigate including NOGAPS model output from FNMOC and GEM model output from Environment Canada to future casestudies.
- Results of the COMET Case Study survey have been tabulated and some of the results include:
- Usage of data
66% use the data for operational meteorological training
48% use the data to identify scientific concepts
45% use the data to research a particular event
31% use the data to research a phenomena
- Data Delivery
83% would prefer to have the cases delivered via CD
- Data Visualization
76% are using GEMPAK or McIDAS to view the datasets
38% are using AWIPS
21% using other means of display
- Data Product Utilization
79% use satellite imagery
69% use radar products
69% use model output
55% use surface and upper air reports
24% use text bulletins
17% use ACARS data
- Phenomena desired as subjects of future studies
55% Heavy Snow
28% Record cold and heat
- Complete results can be found at
- In response to the demand for the cases to be delivered via CD, we will begin offering CD's as a media choice in the near future.
- The upcoming year will offer some changes to the case study project. COMET plans to release only 6 case in 2002, instead of the 12 we released in 2001. The benefit of this change is that the cases will be more enriched. This will be in the form of higher resolution datasets, increased exercise materials, the inclusion of enhanced graphics and metadata for ease of training and education, and the implementation of the Warning Event Simulator (Displaced Real-Time Environment) for the AWIPS versions of the cases.
- We continue to explore other delivery systems than CODIAC such as MEL and other data delivery servers and digital collections to successfully include the case study project within current digital library initiatives.
- Continued improvements in the HTML interface.
- "Other case studies of interest" page now includes more case study and data links
- Main page has new look and ease of navigation
- COMET's page also has a new look and has grouped the casestudies into types of events.
