The tornado information comes partly from A Tornado Climatology for Wisconsin, by Pamela Knox and others, published by Wisconsins Geological and Natural History Survey and still available. Pam Knox, former Wisconsin State Climatologist, appeared frequently on WHA during the 1990s. | ||||||||

For More Information Museum, Tokyo

Geocosmos—SSEC
is contributing real-time worldwide weather imagery to a unique Japanese
science museum. Geocosmos is a giant globe hung in a new Tokyo science
and technology museum. Covered with thousands of LEDs, the globe can project
any high-resolution image. Geocosmos developers have chosen to provide
up-to-date weather information direct from SSECs Data Center via
the Internet.
Mars Scout missionSanjay Limaye is co-investigator on a newly chosen Mars concept study. MACO, or Mars Atmospheric Constellation Observatory, proposes a network of microsatellites around Mars to characterize the 3-D structure of the atmosphere, giving a new look at Martian climatology. It combines the talents of scientists from the University of Arizona, where the principal investigator, Robert Kursinski, is based, the Jet Propulsion Laboratory, and the University of WisconsinMadison, where Limaye is a planetary scientist. According to Space News, June 18, the ten innovative concepts chosen will help NASA shape a broad competition that would pepper Mars with small missions in the future. NASA will evaluate the concepts in six-month studies for possible new Mars Scout missions competing for a 2007 launch. Numerical
Weather AnalysisJames
Jung (CIMSS) and Robert Aune (NOAA, stationed at SSEC in the Advanced
Satellite Products Team) continue to test GOES Sounder products in numerical
models used by the National Weather Service. To accommodate the Cloud
Top Pressure product in the Eta Data Assimilation System, the NWS forecast
model, Jung uses a nudging approach to adjust the cloud field
to generate a more realistic cloud and moisture field. To initialize clouds
in the National Centers for Environmental Predictions Rapid Update
Cycle model, an aviation forecasting tool, Aune uses cloud-top pressure
and effective cloud amounts retrieved from GOES-8 and GOES-10 sounder
data. The Forecast Systems Laboratory has shown that forecasts are improved
by incorporating these data.
Satellite
Data ApplicationsTony
Schreiner and Scott Bachmeier (CIMSS) and Tim Schmit (NOAA) developed
a technique to identify snow during the day time. The procedure uses visible
and shortwave infrared bands of the Geostationary Operational Environmental
Satellite (GOES) Sounder. After incorporating the technique into the CIMSS
current GOES sounder cloud mask, comparisons using last winter's data
showed improvement over the routine sounder cloud product.
Satellite
developmentCIMSS scientists and NOAA counterparts in the
Advanced Satellite Products Team are supporting design of the proposed
next-generation geostationary sounding instrument, called the Advanced
Baseline Sounder. Simulating the ABS high spectral resolution capabilities,
Tim Schmit showed that its retrieval of thin cloud measurements are significantly
improved over those of GOES-8. Jun Li and Tim Schmit showed that the retrieval
of both temperature and moisture profiles are significantly improved with
the high-spectral resolution data and that both profiles meet National
Weather Service specifications.
For the planned
NPOESS program, C. Justice (University of Maryland-College Park) asked
Elaine Prins (NOAA) to provide input on the projected performance of VIIRS,
the Visible and Infrared Imaging Radiometer Suite, a payload being prepared
for the next generation of U.S. polar-orbiting satellites. Prins produced
summary graphics outlining the impact of the VIIRS high resolution 11
micron channel (375 m) on sub-pixel fire characterization. She found that
if the VIIRS saturation brightness temperature remains at the proposed
340 K, sub-pixel characterization of fire size and temperature estimates
will be limited to only the smallest fires; most fires will saturate the
11 micron band. A saturation brightness temperature of 675 K is being
requested of the instrument designers.
Fire
Detection—Elaine Prins (NOAA) is working with R. Valdez
of the National Zoos Amazon division to integrate GOES Biomass Burning
Monitoring information into an online Geographic Information System (GIS)
venue to be featured at the Zoo. Valdez also may highlight fires in the
Amazon for a future GIS Day at the zoo. This would include a focus on
how environmental satellites are used to detect fires in the region.
Florida FiresThe CIMSS GOES Gallery featured a
very large smoke plume from fires burning in northern Florida on May 24-25.
With their GOES-8 Wildfire Automated Biomass Burning Algorithm products,
Chris Schmidt and Elaine Prins identified numerous fire pixels associated
with these fires that burned approximately 20000 acres by the morning
of May 25. Scott Bachmeier produced imagery and animations using GOES-8.
An shortwave infrared image from the Moderate Resolution Imaging Spectroradiometer
reveals a very large hot spot. MODIS and GOES data are received directly
into SSEC.
Useful DataGail
Bayler (CIMSS) and Gary Wade (NOAA) retrieved four months of archived
GOES sounder products for C. ODell of the Observational Cosmology
Group at UWMadisons Department of Physics. The data, total
precipitable water and cloud parameters, are used to correct astronomical
measurements taken at the Pine Bluff Observatory near Madison. ODell
wrote, We highly used the data set we got from you last year (March-May
2000); it was interesting to see our detector response increase (at 30
GHz) as the pwvs [precipitable water vapor] went up.
To increase
understanding of relationships between microphysical and dynamical processes,
Jeff Key provided satellite retrievals of cloud particle phase, particle
effective radius, and optical depth derived from NOAAs Advanced
Very High Resolution Radiometer data to Dr. Ismail Gultepe of the Meteorological
Service of Canada. Gultepe is comparing the satellite-derived microphysical
cloud properties to those measured by aircraft during the Alliance Icing
Research Study field project that took place over Ontario and Quebec regions
of Canada during the winter of 19992000.
Field
ExperimentTo improve calibration of the Terra satellite
instrument MODIS, Terra eXperiment 2001 took researchers and technical
staff to San Antonio, TX in March. SSECs Scanning-High-resolution
Interferometer Sounder and NASAs MODIS Airborne Simulator (MAS)
flew on the ER-2, a research aircraft that has played a major part in
several SSEC-sponsored field experiments.
