MODIS Polar Winds Forecast Impact (3DVAR) Northern Hemisphere Current Operational Users: European Centre for Medium-Range Weather Forecasts (ECMWF), Jan 2003 NASA Global Modeling and Assimilation Office (GMAO), 2003 Deutscher Wetterdienst (DWD), Nov 2003 Japan Meteorological Agency (JMA), May 2004) Canadian Meteorological Centre (CMC), Sept 2004 US Navy (FNMOC), Oct 2004 UK Met Office, Feb 2005 National Centers for Environmental Prediction (NCEP), Nov 2005 Northern Hemisphere Anomaly correlation for 500 hPa geopotential, each experiment verified against its own analysis. Forecast scores are the correlation between the forecast geopotential height anomalies, with and without the MODIS winds, and their own analyses. (From ECMWF) (Jeff Key)
