  23. Future GOES Sensor Technologyand Product Improvements Primary Goals • Meet simultaneous global, synoptic and mesoscale data needs • Eliminate seasonal eclipse outages • Improve the temporal and spatial resolution of the Imager • Improve the spatial coverage and vertical resolution of the Sounder

  24. Future GOES Sensor Technology And Product Improvements Advanced Baseline Imager (ABI) Hyperspectral Environmental Suite (HES) • Improved severe weather detection/forecasting • Improved cloud phase and droplet size information • Improved temperature/water vapor soundings • Improved satellite derived winds • Improved observation of large scale flow • Improved sea surface temperatures • Improved depiction of stability • Improved surface emissivity • Improved quantitative precipitation estimates • Improved mesoscale model performance

  28. HES: Hourly Coverage

  29. HES Nears Raob-like Depiction of Atmosphere while Providing an Order of Magnitude Increase in Temporal Resolution Information Content for Moist Atmospheres interferometer current Number of channels RAOB (USA) - over land - 1 hour ascent - 300 km separation - 12 Z and 00Z only HES (USA)- land and ocean areas - nearly instantaneous obs - 10-50 km separation - hourly repeat/RSO capability A doubling of the critical low-level moisture information (from the current sounder)

  30. 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

  31.
