Manuscript on GOES Sounding Improvement and Applications Published: A
manuscript entitled "GOES sounding improvement and applications to
severe storm
nowcasting" has been published in Geophysical Research Letters.
Coauthors are Zhenglong Li, Jun Li, W. Paul Menzel (CIMSS), Timothy J.
Schmit (STAR), James P. Nelson III (CIMSS), Jaime Daniels (STAR), and
Steven A. Ackerman (CIMSS). This paper summarizes an improved clear-sky
retrieval algorithm for atmospheric temperature and moisture profiles
from Geostationary Operational Environmental Satellite (GOES) Sounder
radiance measurements, and its applications on depicting the
preconvective environment surrounding a tornadic supercell.

ITEMS FOR THE DIVISION CHIEF, CoRP:
Cross-Validation Skill of GOES-based Features in Hurricane Prediction: Hurricanes, and particularly major hurricanes, will often organize a secondary eyewall at some distance around the primary eyewall. These events are generally associated with marked changes in the intensity and structure of the inner core, such as large and rapid deviations of the maximum wind and significant broadening of the surface wind field. The latter has particularly dangerous consequences in terms of storm surge and wind damage extent during landfall events. Despite the importance of secondary eyewall formation in hurricane forecasting, there is presently no objective guidance to diagnose or forecast these events. We have completed a cross-validation of our new algorithm that will provide forecasters with a probability of imminent secondary eyewall formation. The algorithm is found to be skillful, and when Geostationary Operational Environmental Satellite (GOES)-derived features are added to the algorithm, the skill increases measurably. (J. Kossin, CIMSS, 608-265-5356)

CIMSS VISIT Activities: The Virtual Institute for Satellite Integration Training (VISIT) distance learning lesson "Water Vapor Imagery and Potential Vorticity Analysis" was led by staff from the Cooperative Institute for Meteorological Satellite Studies (CIMSS) on February 6, 2008. Forecasters from two separate National Weather Service (NWS) forecast offices (Albany, New York and Glasgow, Montana) participated in the VISIT lesson. (S. Bachmeier, CIMSS, 608-263-3958)
GOES-13 Imager 13.3 micron Spectral Response: A telecon was held with NOAA/NESDIS Office of Satellite Operations (OSO), Satellite Applications and Research (STAR) and others. The topic was the cold bias of the GOES-13 Imager 13.3 micrometer band discovered by Cooperative Institute for Meteorological Satellite Studies (CIMSS) during the GOES-13 NOAA Science Test. The process was discussed to possibly modify the GOES-13 Imager channel 6 Spectral Response Functions (SRF). To assist X. Wu (STAR) in validating the CIMSS results, GOES-13 Imager Man computer Interactive Data Access System (McIDAS) area files were supplied. Given that Comprehensive Large Array-data Stewardship System (CLASS) does not archive non-operational satellite data such as GOES-13, the data were acquired from the Space Science and Engineering Center (SSEC) Data Center at the University of Wisconsin-Madison.

ABI Cloud Mask Seminar: Andrew Heidinger presented a seminar on the GOES-R Advanced Baseline Imager (ABI) cloud mask to the GOES-R Algorithm Working Group (AWG) application teams in Camp Springs, Maryland. The ABI cloud mask has been applied to data from three different geostationary imagers and is available for AWG members for testing in their specific applications. (A. Heidinger, E/RA2, 608-263-6757)
Paper Submitted on Coordinated Satellite Observations During IPY: A paper titled "Coordinated Satellite Observations during the International Polar Year 2007-2008: Towards achieving a Polar Constellation" was submitted to Space Research Today. The authors are M. Drinkwater (European Space Agency), K. Jezek (Ohio State University), and J. Key (NESDIS/STAR). The paper describes three related projects involved in the implementation of recommendations for spaceborne observations during the International Polar Year (IPY): the Global Interagency International Polar Year Polar Snapshot Year (GIIPSY), the World Meteorological Organization (WMO) Space Task Group (STG) for the International Polar Year (IPY), and the Integrated Global Observing Strategy Cryosphere Theme.
