Cloud Climatology Milestone Completed:  A new upper tropospheric cloud climatology was been produced within the AVHRR Pathfinder Atmospheres Extended (PATMOS-x) project.  The technique uses the 11 and 12 micron channels on NOAA's Advanced Very High Resolution Radiometer (AVHRR) to estimate cloud temperature and emissivity.  The approach works well for all orbits and is therefore well-suited to deriving a climatology from the AVHRR whose orbit changed over time.  Comparisons with MODIS show good agreement for most regions and most clouds.  The derived climatology also shows good agreement with other climatologies of upper tropospheric cloud.  The products are available through the Cooperative Institute for Meteorological Satellite Studies (CIMSS) or through STAR and are contained within the PATMOS-x data-set.

Preliminary Look at GOES-11 Sounder Radiances Shows Good Quality:  Pre-operational Geostationary Operational Environmental Satellite (GOES)-11 Sounder brightness temperatures, in 18 infrared spectral bands, were compared to GOES-10 Sounder values.  Even with the varying view angles due to the different satellite sub-points, fair agreement of the radiance imagery from the two sensors was observed.  GOES-11 shows less instrument noise, especially evident in bands 12 and 15.  For a comparison of GOES-10 to GOES-11 remapped brightness temperatures, see http://cimss.ssec.wisc.edu/goes/sounder/goes11/sndr_11.html. These data were acquired via the Space Science and Engineering Center (SSEC) Data Center. (T. Schmit, E/RA2, 608-263-0291, tim.j.schmit@noaa.gov)

Direct Broadcast MODIS Winds Now Available in BUFR Format: The Moderate Resolution Imaging Spectroradiometer (MODIS) polar winds that are generated at direct broadcast sites in Tromsø, Norway, and McMurdo, Antarctica, are now available in Binary Universal Form for the Representation of Meteorological Data (BUFR). This data file format was requested by a number of numerical weather prediction centers.  The data are currently available on a Cooperative Institute for Meteorological Satellite Studies (CIMSS) FTP server, but will soon be available on EumetCast.

Abstracts Submitted for NWA Annual Meeting:  Two abstracts were submitted for the National Weather Association (NWA) annual meeting to be held in October 2006.  One abstract is entitled "Operational Implications of the Geostationary Operational Environmental Satellite (GOES)-R Advanced Baseline Imager (ABI) and Hyperspectral Environmental Suite (HES)" by T. Schmit and others.  The other abstract is entitled "Improved resolution and consistency in the quest for better utilization of GOES Sounder products" by G. S. Wade and collaborating (Cooperative Institute for Meteorological Satellite Studies (CIMSS) and Advanced Satellite Products Branch (ASPB) and other colleagues.  (T.
