ACCOMPLISHMENTS:
JCSDA Meeting Participation: J. Key, R. Aune, and J. Mecikalski participated in the Office of Research and Applications (ORA) meeting to discuss data assimilation activities at the Cooperative Institute for Meteorological Satellite Studies (CIMSS) and within the Advanced Satellite Products Team (ASPT) that are relevant to the new Joint Center for Satellite Data Assimilation (JCSDA). The meeting took place on Monday, March 18 at the National Oceanic and Atmospheric Administration (NOAA) Science Center in Camp Springs. (J. Key, E/RA2, 608-263-2605, R. Aune, E/RA2, 608-262-1071, J. Mecikalski, CIMSS, 608-262-1023)
IGARSS Proceedings Papers Submitted: Three
proceedings papers (not refereed) were submitted for the
International Geoscience and Remote Sensing Symposium (IGARSS) to be
held in Toronto in June 2002. "Antarctic Cloud Radiative Forcing
at the Surface Estimated from the ISCCP D2 and AVHRR Polar Pathfinder
Data Sets, 1985-1993", by M. Pavolonis (Cooperative Institute for Meteorological
Satellite Studies (CIMSS)) and J. Key describes the effect of clouds on
the surface radiation budget of Antarctica. "Detection and Analysis
of Atmospheric Temperature Inversions with MODIS", by Y. Liu (CIMSS) and
J. Key, presents a method for detecting low-leveltemperature inversions
in the polar regions. "Arctic Climate Characteristics and Recent
Trends Based on the AVHRR Polar Pathfinder Data Set", by X. Wang (CIMSS)
and J. Key, evaluates trends in Arctic cloud and surface propertiesover
the past 20 years. (J. Key,
E/RA2, 608-263-2605)

Space-based Lidar Winds OSSE: National Centers for Environmental Prediction (NCEP) and collaborators are developing an Observing System Simulation Experiment (OSSE) designed to estimate the impact of lidar wind profiles on numerical weather prediction. As part of this OSSE, cloud-track and water vapor winds are being simulated based on input and statistical analysis provided by the Cooperative Institute for Meteorological Satellite Studies (CIMSS) and the National Environmental Satellite, Data, and Information Service (NESDIS). A meeting was held during the THe Observing system Research and Prediction EXperiment (THORPEX) workshop to discuss this OSSE. (C. Velden , CIMSS, 608-262-9168)

Northcentral US Heavy Snow Event: A heavy snow event (with accumulations as high as 19 inches in South Dakota, 21 inches in Minnesota, and 20 inches in Wisconsin) over the north central portion of the United States on March 14, 2002 provided the opportunity for researchers at the Cooperative Institute for Meteorological Satellite Studies (CIMSS) to compare water vapor imagery from the Moderate-resolution Imaging Spectroradiometer (MODIS), Geostationary Operational Environmental Satellite (GOES) -8, and GOES-10. The higher spatial resolution of the MODIS water vapor channel data (1 km, versus 4x8 km for GOES Imagers) allowed better detection of the axis of a jet streak feature crossing the Kansas/Nebraska border. Brightness temperatures were generally 2-6 C warmer across this scene on the MODIS data (especially in the region of the dry slot associated with the axis of the jet streak), since the weighting function peaks lower in the atmosphere for the MODIS water vapor channel than it does for the GOES-08/GOES-10 water vapor channel. The more extreme viewing angle from GOES (zenith angles near 50 degrees) also contributes to the colder brightness temperatures compared to MODIS. http://cimss.ssec.wisc.edu/goes/misc/020314/020314.html.

THORPEX Workshop: As a member of the scientific steering committee, Chris Velden (Cooperative Institute for Meteorological Satellite Studies (CIMSS)) attended the planning workshop for THe Observing system Research and Prediction EXperiment (THORPEX). Several Thorpex Observing System Tests (TOST) field programs are planned for this decade, and will include current and new satellite-based instruments. Extensive adaptive sampling strategies as well as data assimilation technique development will play an integral part of these TOSTs. A THORPEX science plan is being drafted and will be presented to the USWRP and WWRP this fall. (C. Velden , CIMSS, 608-262-9168)
VISITORS:
Visitors to CIMSS: The Cooperative Institute for Meteorological Satellite Studies (CIMSS) is hosting scientists from the Japan Meteorological Society and Indian Meteorological Service next week to discuss ongoing satellite-derived winds research and code development. Drs. Yoshiki Kajino and Sant Prasad will be trained on the latest CIMSS/NESDIS (National Environmental Satellite, Data, and Information Service) winds tracking techniques, and will take back with them the latest algorithm/code advances to their respective institutes for implementation. Dr. Prasad arrives at CIMSS after spending two weeks on satellite winds training at NESDIS. (C. Velden , CIMSS, 608-262-9168, J. Daniels, E/RA2, 301-763-8204)
