ITEMS FOR THE OFFICE DIRECTOR, ORA:
GOES-9 Imager Data Acquired at SSEC: After hardware and firmware modifications to the satellite modem, the Space Science and Engineering Center (SSEC) was able to acquire the Geostationary Operational Environmental Satellite (GOES)-9 Imager signal via the domsat, AMC 4. SSEC began archiving the GOES-9 imager data onto tape as of 1518 UTC on April 23. SSEC also is sending the raw data to the National Climate Data Center (NCDC) online archive via the Internet II. The image quality is comparable to previous data from GOES-9. (D. Wade, SSEC, 608-263-0527, J. Robaidek, SSEC, 608-262-6025, T. Schmit, E/RA2, 608-263-0291)
First CSBT Product from GOES-9 Imager: With
the resurrection of the Geostationary Operational Environmental
Satellite (GOES) -9 Imager stationed over the western Pacific (sub
satellite point of 0 north latitude and approximately 155 east
longitude), the opportunity to produce Clear Sky Brightness Temperature
(CSBT) data is now a reality. Routine generation (hourly) of this
experimental product is expected to begin no later than May 1, 2003.
Spatial resolution will be the same as CSBT data for GOES-10 and
GOES-12. (T. Schreiner

ITEMS FOR THE DIVISION CHIEF, ARAD:
VIIRS Operational Algorithm Team Meeting: A.
Heidinger attended the Visble Infrared Imager Radiometer Suite
(VIIRS) Operational Algorithm Meeting (OAT) on April 16 at the Northrup
Grumman facility in Redondo Beach, California. Topics discussed
included the evolution of the VIIRS algorithms into a operatioanal
system and lessons learned from the MODIS (Moderate Resolution Imaging
Spectrometer) relevant to VIIRS. The next meeting of the VIIRS OAT
will take place in July. (A.
Heidinger, E/RA2, 608-263-6757)
Validation of Water Vapor from GOES-12 with Surface Measurements: The Geostationary Operational Environmental Satellite (GOES)-12 was made operational on April 1, 2003, replacing the GOES-8 satellite platform. The Cooperative Institute for Meteorological Satellite Studies (CIMSS) is processing near realtime derived products (total precipitable water vapor (TPW), cloud top pressure, lifted index and others) from GOES-12 sounder radiances. Near realtime validation using meteorological and surface-based remote sensing observations from the Department of Energy's (DOE) Southern Great Plains (SGP) site is ongoing. GOES-12 physically retrieved TPW shows good skill in adjusting the first guess water vapor values to more closely fit those observed at the Lamont, Oklahoma DOE ARM Central facility. (W. Feltz, CIMSS, 608-265-6283)

(diamonds), GOES-12 physically retrieved (pluses), radiosonde (stars),
and microwave (line) radiometer total precipitable water (TPW) for
April 14, 2003 over the Department of Energy Atmospheric Radiation
Measurement (DOE ARM) central facility near Lamont, Oklahoma.
Notice the positive adjustment the GOES-12 radiances apply to the ETA
first guess TPW fitting the microwave and radiosonde TPW.
GIFTSPAP Meeting: A group of Cooperative
Institute for Meteorological Satellite Studies (CIMSS) scientists
attended the NOAA Geostationary Imaging Fourier Transform Spectrometer
(GIFTS) Product Assessment Plan (GIFTSPAP) kickoff meeting in Suitland,
MD on 22 April. Presentations were given on CIMSS' recent efforts and
future plans for Level 0 to 1 algorithm development, ground data system
design, and algorithm development for products including cloud and
surface properties, atmospheric temperature and water vapor profiles,
and winds. (S.
Ackerman, CIMSS, 608-263-3647)
First Routine GOES-12 Imager Cloud Product: The Geostationary Operational Environmental Satellite (GOES) -12 Imager Cloud Product using the Carbon Dioxide (CO2) Absorption Technique (CAT) is now being routinely processed at the Cooperative Institute for Meteorological Satellite Studies (CIMSS). Every three hours a hemispheric image of Cloud Top Pressure (CTP) and Effective Cloud Amount (ECA), utilizing every field of view, is being generated. The advantage of using the CAT is to provide a realistic definition of CTP and ECA for high, thin clouds. The products are available at http://cimss.ssec.wisc.edu/goes/realtime/grtmain.html#imgrcld. (T. Schreiner , CIMSS, 608-263-6754, T. Schmit, E/RA2, 608-263-0291, G. Wade, E/RA2, 608-263-4743)

Software for Averaging Satellite Images Made
Available: The Cooperative Institute for Meteorological Satellite
Studies (CIMSS) provided specialized Man computer Interactive Data
Access System (McIDAS) software to both the National Aeronautics and
Space Administration (NASA) Langley Research Center and UNIDATA. This
software has a number of options, including progressive image
averaging. The software provides a starting point for minimizing the
Geostationary Operational Environmental Satellite (GOES)-9 visible high
frequency noise, and can currently be used to produce a loop of
satellite images showing the benefits of higher spatial resolution
data. One such loop is at:
http://cimss.ssec.wisc.edu/goes/cloud/loop/imgproc_example_color.html.
UNIDATA may use this software to create a visualization for
presentation to congressional staffers. (T. Schmit, E/RA2,
