WVTI Study - Satellite Data Coverage Map

The map above shows satellite data coverage and analysis regions used in the various water vapor transport studies. For the 1987-1988 study, GOES 7 Pathfinder data was used over a limited portion of the full disk to derive winds and humidity over the red box. This analysis region extends from 45N-45S and from 30W-120W.
The 1997-1998 study uses GOES 8/9/10 data and extends the analysis region farther into the Pacific to 160W but limits the southern coverage to 30S. In order to get this coverage (medium gray box), data from the GOES 8 Northern Hemisphere Extended region and the GOES 9/10 northern and southern hemisphere regions are used (since the GOES I/M satellite series only collects full disk data on three hour cycles). This analysis region may be extended even further west (dark gray box) with the inclusion of limited sectors from the GMS (Geostationary Meteorological Satellite - Japan) data.
