Polar Winds in the Press: The positive impact of new satellite data products, including the Moderate Resolution Imaging Spectroradiometer (MODIS) polar winds, on weather forecasts is described in an article in the magazine Aviation Week and Space Technology titled "Spaceborne Scientific Sensors Add Valuable Weather Forecast Data" (http://www.aviationweek.com/avnow/news/channel_awst_story.jsp?id=news/12125p1.xml).

Paper on Variability of Arctic Ice Extent Published: A paper titled "Clues to variability in Arctic minimum sea ice extent" was published in the journal Geophysical Research Letters (Vol. 32, 2005). The paper, co-authored by Jennifer Francis, Elias Hunter (Rutgers University), Jeffrey Key (NESDIS), and Xuanji Wang (Cooperative Institute for Meteorological Satellite Studies), presents an analysis of new satellite-derived fields of winds, radiative forcing, and advected heat that reveals distinct regional differences in the relative roles of these parameters in explaining variability in the northernmost ice edge position. In all six peripheral seas studied, downwelling longwave flux anomalies explain the most variability – approximately 40% – while northward wind anomalies are important in areas north of Siberia, particularly earlier in the melt season.
