Geostationary Hyperspectral IR Sounder Added value for weather forecasts and many other uses

Over the past several decades, there have been many Observing System Simulation Experiment (OSSE) studies dedicated to the importance of GEO hyperspectral IR sounders for weather forecasts.

Local severe storms forecast and nowcast

On local severe storms, Li et al. 2018, show that GEO hyperspectral IR sounders may provide value-added impact on the forecast as well as analysis field.
