Future GOES
Future GOES will address all four key remote sensing areas
spatial resolution – what picture element size is required to identify feature of interest and to capture its spatial variability;
spectral coverage and resolution – what part of EM spectrum at each spatial element should be measured, and with what spectral
resolution, to analyze an atmospheric or surface parameter; temporal resolution – how often does feature of interest need to be
observed; and radiometric resolution – what signal to noise is required and how
accurate does an observation need to be.

Current Requirement
HES• The Hyperspectral Environmental Suite (HES) will be located on a
geostationary platform. – 2013– NOAA operational– Currently in formulation phase
• HES is an outgrowth of earlier ABS efforts– HES includes the functionality of the old Advanced Baseline Sounder
(ABS) – HES has been expanded to include other capabilities for environmental
monitoring employing the improved temporal resolution from GEO. • Coastal Ocean• Open Ocean• Land
HES-IR Tasks• HES - Disk Sounding (HES-DS)
– Provide vertical moisture and temperature information, and other environmental data that will be used by NOAA and other public and private agencies to produce routine meteorological analyses and forecasts
– Provide data that may be used to extend knowledge and understanding of the atmosphere and its processes in order to improve short/long-term weather forecasts.
• HES - Severe Weather / Mesoscale (HES-SW/M)– Provide environmental data that can be used to expand knowledge of
mesoscale and synoptic scale storm development and provide data that may be used to help in forecasting severe weather events.
– Backup mode in the event of a GOES-R ABI failure (both).
HES-Disk Sounding (HES-DS) task
• Spatial Resolution– IR: Threshold=10 km, Goal=2 km, – Vis: Threshold=1.0 km, Goal= 0.5 km
• Coverage rate (Threshold)– 62 degree LZA / hour
at 10 km resolution• Coverage area must
be flexible and selectable.
HES-Severe Weather/Mesoscale task• Spatial Resolution
– IR: Threshold=4 km, Goal=2 km, – Vis: Threshold=1.0 km, Goal= 0.5 km
• Coverage rate– 1000 km x 1000 km (locations vary) in 4.4 minutes– Coverage area must be flexible and selectable.
• Spectral coverage:– Specific examples are cited in the MRD, same as HES-DS
• Spectral resolution: – 15 um CO2 band: 0.6 cm-1, Windows: 0.6-1.0 cm-1, Ozone: 1 cm-1,
H2O: 1-2 cm-1, near 4 um: 2.5 cm-1, Visible: 0.18 um
