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
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
Advanced Baseline Imager (ABI) 14 - 18 channel large focal plane array • .5 km VIS resolution • 2 km IR resolution • 15 minute full disk coverage • 5 minute CONUS coverage • 1000 x 1000 km coverage/30 sec
ABI Channel Selection • 11.2: clouds, low level water vapor, fog, winds; • 0.64: daytime clouds, fog, aerosol, vegetation • 6.15: upper tropospheric flow, winds • 3.90: nighttime low clouds, fog, fire detection • 12.3: low level water vapor, volcanic ash • 13.3: cloud top parameters, heights for winds • 7.00: mid-tropospheric flow, winds • 1.61: daytime clouds/snow, water/ice clouds • 8.50: sulfuric acid aerosols, cloud phase, sfc • 10.35: cloud particle size, sfc properties • 0.86 : daytime clouds, fog, aerosols, NDVI • 1.375: daytime thin cirrus detection

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)
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
