Global Instability Indices - MTG - 0 degree

The Global Instability Index (GII) product provides information about instability of the atmosphere and thus can identify regions of convective potential. GII is a segmented product that uses an optimal estimation scheme to fit clear-sky vertical profiles of temperature and humidity, constrained by NWP forecast products, to FCI observations in the seven channels WV6.3, WV7.3, IR8.7, IR9.7, IR10.5, IR12.3, and IR13.3. The retrieved profiles are then used to compute atmospheric instability indices: Lifted Index, K Index, Layer Precipitable Water, Total Precipitable Water. The GII product is available in netCDF format, every 10 minutes, in 3x3 pixels (IR channels), leading to a spatial resolution of 6 km at nadir.
