IMS Snowcover Product Tested: The Interactive Multisensor Snow and Ice Mapping System (IMS) snowcover product generated by the Satellite Analysis Branch (SAB) is being evaluated at the Cooperative Institute for Meteorological Studies (CIMSS). The product was assimilated into the CIMSS Regional Assimilation System (CRAS), replacing an older product that was generated by the Climate Prediction Center (CPC). Prelimiary results indicate the product maintains good time continuity and, at 25-km horizontal resolution, does a reasonable job of delinating snow/no-snow edges. A corresponding improvement in forecasts of low-level temperatures is expected. (R. Aune, E/RA2, 608-262-1071)

GOES-9 Performance Summary: A presentation
was created that summarized the current performance of the Geostationary
Operational Environmental Satellite (GOES) -9. The quality of the radiances
from both the imager and sounder was addressed, along with several products
(retrievals and clouds) derived from sounder data. Overall, the main limitation
of GOES-9 is high frequency oscillation in the imager full resolution visible
band, yet the meteorological information is good. The presentation is available
upon request. (T. Schmit,

Abstract Submitted to IGARSS: An abstract
titled "Correlation of MODIS aerosol and MOPITT carbon monoxide measurements
over areas of biomass burning: case studies" was submitted for presentation
at the International Geoscience and Remote Sensing Symposium (IGARSS) to
be held in Toronto in June 2002. The paper is a collaborative effort
between the Measurements of Pollution In The Troposphere (MOPITT) and MODerate-resolution
Imaging Spectroradiometer (MODIS) aerosol teams, the Cooperative Institute
for Meteorological Satellite Studies (CIMSS), and the Office of Research
and Applications (ORA) Advanced Satellite Products Team (ASPT).
The paper will investigate the relationship between Geostationary Operational
Environmental Satellite (GOES-8) Automated Biomass Burning Algorithm (ABBA)
derived fire products and aerosol and carbon monoxide (CO) plumes for case
studies throughout the Western Hemisphere. It represents a first
step in combining GOES and Earth Observing System (EOS) multi-sensor derived
products to investigate the relationship between biomass burning, aerosols,
and CO. (J. Feltz, CIMSS, 608-263-3434, E.

More IGARSS Abstracts: Three abstracts were submitted for presentation at 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), J. Key, and S. Ackerman (CIMSS), presents a method for detecting low-level temperature 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 properties over the past 20 years. (J. Key, E/RA2, 608-263-2605)
Reviews of AVHRR Fire Product Manuscripts: Two manuscripts submitted to the Journal of Geophysical Research Atmospheres (JGR-Atmospheres) were reviewed. The manuscripts were titled "Interannual changes of active fire detectability from long-term records of the Advanced Very High Resolution Radiometer" and "Evaluation of algorithms for developing a long-term fire inventory across North America and an examination of 2000 fires in the western US from satellite." The manuscripts are companion papers which describe and evaluate Advanced Very High Resolution Radiometer (AVHRR) sensor issues, techniques, and algorithms for detecting active fires and mapping burned areas. AVHRR data are being used to create a long-term consistent remote sensing fire inventory for North America from 1985 on. (E. Prins, E/RA2, 608-263-6607)

Positive Impact of MODIS Polar Winds: Lars Peter Riishojgaard of the National Aeronautics and Space Administration (NASA) Data Assimilation Office (DAO) reported that the DAO is seeing a distinct impact of satellite-derived polar winds on model forecasts. A 10-day case study of cloud-track and water vapor winds from the MODerate-resolution Imaging Spectroradiometer (MODIS) was provided to the DAO by scientists at the Cooperative Institute for Meteorological Satellite Studies (CIMSS) and the Advanced Satellite Products Team (ASPT). Dr. Riishojgaard also reported that the MODIS winds-minus-forecast metric indicates a "fairly dramatic impact", especially for water vapor winds, and especially in the mid-troposphere. (J. Key, E/RA2, 608-263-2605, C. Velden , CIMSS, 608-262-9168, D. Santek, CIMSS, 608-263-7410)

First Phase of Office Renovation Complete: In preparation for the arrival of new furniture, researchers working at the University of Wisconsin's Cooperative Institute for Meteorological Satellite Studies (CIMSS) have finished the first phase of the process: moving out into temporary office space. Nine employees have packed and moved all of their materials including computers, office equipment, electronic storage media, books, journals, and other office papers. Most materials, with the exception of computers, are being stored while the employees occupy temporary office space that they created this week. The final clean-up of their office was done Friday, January 11 in anticipation of painters coming Monday, January 14; new carpet should be laid down Tuesday, January 15 and the new office furniture has already arrived and can be moved in as soon as the painting and carpeting is finished.
