STAR Satellite Rainfall Estimates
Hydro-Estimator - South America
Automatic Satellite-Derived Precipitation Estimates
This home page provides real time rainfall rate estimates over South
America based on cloud top temperature measurements from the GOES-East
satellite 10.7 micron channel. The estimates are not available when
GOES-East is in rapid scan mode (only the Northern Hemisphere is observed). This
The estimates may be too high for cold cloud tops and too low for warm cloud tops.
The use of this product is at the discretion of the user.
For more details see this technique description.
The model has been updated (January 2000) to include a moisture
correction based on the NCEP GFS model, and to reduce the overestimates
which occur in wide-spread convective regimes.
