GOES-12 4km Water Vapor Channel
A mid-level water vapor feature associated with
moderate turbulence was depicted better by the
GOES-12 imager than either of the operational
GOES-8 or GOES-10 imagers. One report of
turbulence aloft was over Alamosa (ALS) CO.

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
