GOES/I-M
Strengths
- Consistent space resolution over
NWS Forecast Area
- Cloud drift and water vapor winds
- Cloud heights
- Fog/low cloud detection
- Important boundary information
for pre-storm environments
- If not obscured by high cloud...
- new storm growth
- low altitude boundaries
- Large through small domain
coverage (including
oceans)
"Mechanics"
- 5-channel passive radiometer (imager)
- 19-channel passive radiometer (sounder)
- 4:33(RSO)
- 26 minute line-by-line scans to build "image"
- Image time is the time of the first
scanline
- Note: distance between you and
the first scanline varies!
- Quality Control: navigation and
calibration done before dissemination
