Advances Provided By HES A Geosynchronous Interferometer (HES) will * depict water vapor as never before - mesoscale features of moisture for short-term forecasting * characterize life cycle of clouds - ice / water cloud - cloud particle sizes (better cloud initializations within models) * measure surface temperatures (land and sea) - improved SSTs * distinguish atmospheric constituents with improved certainty - volcanic ash (useful for aircraft routing) With complementary improved weather observing system, HES * enables the best mix of observations of weather systems Using improved NWP models, HES provides * improved winds at more levels for hurricane intensity and trajectory forecasting * improved high resolution moisture / temp fields for QPF * improved cloud information with 4DVAR assimilation for better 2-3 day forecasts
