WRF 3D-var Analysis Group Meeting: The 3-dimensional variational (3D-var) analysis working group for the Weather Research and Forecasting (WRF) system met via teleconference on November 22. The status of the first release of the WRF 3D-var software was reviewed and a release date of May 31, 2003 was set. The first version will support in situ observations, i.e. radiosonde profiles, surface observations, aircraft winds and temperatures, and profiler data. The ability to assimilate space-based observations (radiances, winds) will be developed in subsequent versions. (R. Aune, E/24, 608-262-1071)
ABI Channel
Selection Information Provided: Information was provided to the Office
of Systems Development (OSD) on the relative merits of 2.26 and 1.6 micron
bands on the Advanced Baseline Imager (ABI). Some of the advantages of the
2.26 micron band are an improved particle size, an improved vegetation index
in smoky regions, and an improved aerosol product over land. Of course, there
are still uses for the 1.6 micron band. (T. Schmit, E/RA2, 608-263-0291,

Journal Paper Submitted:
A. Heidinger submitted a paper titled "Relative Merits of the 1.6 and 3.75
micron channels of the AVHRR/3 for cloud detection" to the Canadian Journal of Remote Sensing.
With the KLM-series of polar-orbiting satellites, the 3.75 micron channel
is turned off in favor of the 1.6 micron channel during the day. This paper
explores the significant impact this has on the ability to detect cloud with
the Advanced Very High Resolution Radiometer (AVHRR)/3 during the day. The
results indicate that there are substantial differences in cloud detection
capability using one channel or the other. This will most likely impact the
continuity of the AVHRR climate record for some clear-sky parameters.

Demonstration on GOES Derived Products: T. Schmit gave a demonstration on real-time Geostationary Operational Environmental Satellite (GOES) Sounder products to two National Climatic Data Center (NCDC) Satellite Services Group employees (D. Ghappas and S. Stephens), who were visiting the Space Science and Engineering Center (SSEC) this week. T. Schmit requested that NCDC archive all the operational GOES Sounder derived products (e.g., Derived Product Images). (T. Schmit, E/RA2, 608-263-0291)
Ground Systems Proposal Presentations: Two more proposals from the Cooperative Institute for Meteorological Satellite Studies (CIMSS) and the Advanced Satellite Products Team (ASPT) were presented for support from the Office of Systems Development/Office of Research and Applications Ground Systems project. The presentations were made via video teleconference by T. Achtor (CIMSS) and A. Heidinger (ASPT). This set of proposals were for products from polar-orbiting satellite. (J. Key, E/RA2, 608-263-2605)

CIMSS and EUMETSAT Software Collaboration: Jim Nelson of the Cooperative Institute for Meteorological Satellite Studies (CIMSS) recently supplied software to compute Convective Available Potential Energy (CAPE) to Dr. Marianne Koenig of the EUropean organization for the exploitation of METeorological SATellites (EUMETSAT). This is thesame software currently used at CIMSS to compute CAPE while generating retrievals of temperature and moisture using Geostationary Operational Environmental Satellite (GOES) Sounder radiances. (J. Nelson, CIMSS, 608-263-6013)
CIMSS Newsletter: Volume 3 of the Cooperative Institute for Meteorological Satellite Studies (CIMSS) Newsletter is available. This science news magazine provides recent information about CIMSS' research and education activities. To be added to the mailing list, email Leanne Avila. (S. Ackerman, CIMSS, 608-263-3647)
