Press Coverage of Multi-agency Satellite Fire Detection
and Aerosol Modeling Project: In conjunction with the spring
American Geophysical Union (AGU) meeting, the National Aeronautics and
Space Administration's (NASA) Earth Science News Team issued a press release
regarding the Fire Locating And Monitoring of Burning Emissions (FLAMBE)
collaborative project funded primarily by the NASA Earth System Science
Enterprise Interdisciplinary Science program. This project includes
participation of the U.S. Navy, NASA, the National Oceanic and Atmospheric
Administration (NOAA), the University of Alabama, and the University of
Wisconsin. FLAMBE represents one of the first efforts to track and
predict biomass burning emissions and radiative effects in real-time using
the Geostationary Operational Environmental Satellite (GOES) Wildfire Automated
Biomasss Burning Algorithm (WF_ABBA) fire product as input to the Navy Aerosol
Analysis and Prediction System (NAAPS). The story was picked up by the
United Press International and Scripps wire services and received international
coverage. (E. Prins,

Material Supplied to Support the 0.86 micron Channel
on the ABI: A presentation was sent to D. Flanagan (Office of Systems
Development) to support the spectral narrowing of the 0.86 micron channel
on the Advanced Baseline Imager (ABI). It is shown that the Normalized Difference
Vegetation Index (NDVI) image is improved with the narrower band due to lower
atmospheric moisture absorption. The data used were supplied by Lincoln
Labs during the second National Oceanic and Atmospheric Administration (NOAA)
hyperspectral workshop. The presentation, developed by a undergraduate student,
is avalible upon request. (T. Schmit, E/RA2, 608-263-0291)

Simulated AIRS Data Quantized for ABS Data Compression
Experiments: Scientists at the Cooperative Institute for Meteorological
Satellite Studies (CIMSS) devised an algorithm for properly converting 16-bit
longwave hyperspectral radiance & brightness temperature data from original
32-bit data for Advanced Baseline Sounder (ABS) compression studies. Using
an April 1, 2002, simulated Atmospheric InfraRed Sounder (AIRS) granule
as supplied by Walter Wolf, a quantization study was performed on the longwave
data. The object was to convert the raw longwave radiances into brightness
temperatures (K) and quantize these values into 16-bit integers while retaining
an accuracy of 0.01 K. These datasets will be used by a number of
researchers to investigate lossless data compression of hyper-spectral infrared
data. (T. Schmit,

New Version of SHEBA AVHRR Cloud and Surface Properties
Data Set: A new version of the Advanced Very High Resolution Radiometer
(AVHRR) retrievals of surface, cloud, and radiation characteristics for the
Surface Heat Budget of the Arctic (SHEBA) experiment has been released. The
data is being used for meteorological case studies and as model forcing in
the Arctic Climate Model Intercomparison Project (ARCMIP). See http://stratus.ssec.wisc.edu/products/sheba_caspr/sheba_caspr.html
for more information. (J. Key, E/RA2, 608-263-2605)
NOAA Leadership Training: J. Key attended
the National Oceanic and Atmospheric Administration (NOAA) Leadership Training
course in Silver Spring, Maryland June 3-7. Other Office of Research
and Applications (ORA) participants included J. Brust, M. Goldberg, and
E. Baylor. (J. Key,

Preliminary Comparison of GOES-8 and GOES-11 Total
Precipitable Water: A preliminary comparison of collocated Geostationary
Operational Environmental Satellite (GOES)-8 and GOES-11 Total Precipitable
Water (TPW) data for a region covering the south-central U.S. has been
conducted at the Cooperative Institute for Meteorological Satellite Studies
(CIMSS). These data are from a single time period on June 7,
2002 and were extracted from Single Field of View (SFOV) retrievals of
temperature and moisture that are being generated in near-real time.
The comparison includes retrievals generated over portions of Oklahoma and
Kansas as part of the International H2O Project (IHOP) field experiment.
For 69 total comparisons, the GOES-11 retrieved TPW averaged about
1 millimeter greater than the collocated GOES-8 retrieved TPW. Other
GOES-8 and GOES-11 comparisons are available at http://cimss.ssec.wisc.edu/ihop.
GOES-11 Sounder imagery are generally similar to those from GOES-8, but show
obvious differences including brighter visible channel data, many less noisy
infrared bands (especially 1-3 and 15), and thermal biases (cooler band 13,
warmer band 5). (J. Nelson,

GOES-11 Tracks Mesoscale Vortices in Marine Stratus:
Five minute interval imagery from the Geostationary Operational Environmental
Satellite (GOES)-11 revealed mesoscale vortices within the marine stratus
off the coast of southern California on June 6, 2002. Fog/stratus product
images showed the initial vortex development during the pre-dawn hours, while
the visible channel imagery showed greater detail in the vortex structure
during the first few hours of daylight. The circulation of an offshore Catalina
Eddy was acting to slow the erosion of fog and stratus along the immediate
coast. Images and animations are available at (http://cimss.ssec.wisc.edu/goes/misc/020606/020606.html).
