Global Mosaic of Geostationary Satellite Imagery - Total Operational Weather Readiness - Satellites (TOWR-S)
Global Mosaic of Geostationary Satellite Imagery (GMGSI)
About
The Global Mosaic of Geostationary Satellite Imagery (GMGSI) is a set of products derived from GOES-West, GOES-East, Himawari-9, Meteosat-9, and Meteosat-11. It provides near-global coverage for Visible, Water Vapor, and Longwave Infrared data. One full global image for each of the 3 composite types is produced every 3 hours. GMGSI improved upon and replaced the GINI Global Multi-Satellite Geostationary Satellite Imagery Composite products on December 10, 2020.
Limitations
Latitudinal Coverage: Valid data is produced from 71N to 71S.
Cadence: PDA subscriptions receive hourly updates, while the SBN transmits new composites every 3 hours.




AWIPS
Location: Satellite → Global 5 Sat Composites → Choose Global Visible/Window IR/Water Vapor
Color Maps: Visible: Sat/VIS/ZA (Vis Default)
Water Vapor: Sat/WV/CIMSS_WV
Longwave IR: Sat/IR/CIRA (IR Default)
Sampling: N/A
Quality Flags: None
Technique: The Visible composite band is ~0.6 microns, which may be used to view cloud cover, ice, and snow cover. The Water Vapor band is ~6.7 microns, which shows the amount of water vapor contained in the mid to upper levels of the troposphere. The Longwave/Window IR band is ~12.0 microns, which shows cloud cover and surface temperature.
