GOES-12 Imager Changes

• Move to 75W; Replace GOES-8 in April 2003 • Water Vapor Channel

- Change from 8km to 4km horizontal resolution

• GOES-8/10 12 Micron Channel 5 (Split Window)- Sea Surface Temperature- Volcanic Ash

• GOES-12 13.3 Micron Channel 6 (Atmospheric/Surface Temp)- 8km GOES-12/13, 4km GOES-O,P - Cloud Top Pressure- Improved Height Assignment: Cloud Drift Winds

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
