MSG Global Instability Index<\/h1>\n

Operationally produced by EUMETSAT<\/p>\n

\n

Application:<\/h2>\n

Detection of possible unstable areas through satellite based stability indices in pre-convective environment.<\/p>\n

The Global Instability Index (GII) product consists of four indices which describe the stability of the atmosphere (K-Index, KO Index, Lifted Index, Maximum Buoyancy) together with precipitable water content (Layer precipitable water content, Total precipitable water). Regional Instability Index (RII) is the pixel-based version of the GII, which is produced for a subset of the MSG image disc over Europe, available also every 5 minutes.<\/p>\n

Limitations:<\/h2>\n

Not available in cloudy areas, resolution is 3 x 3 SEVIRI pixels.<\/span><\/p>\n

Pros and Cons:<\/h2>\n

\u2713 Good for following the deviation from the NWP model\u00a0stability indexes<\/span><\/p>\n
