Cloud Fraction and Cloud Cover

Cloud Fraction is derived from the cloud cover product generated using the radiance and reflectance measurements from the thermal infrared and visible channels respectively along with water vapour channel from Very High Resolution Radiometer (VHRR) onboard Indian Geo-Stationary Satellite INSAT-3D.

Planetary Boundary Layer Height

Planetary Boundary Layer Height (PBLH) over the Indian land mass is estimated using vertical profiles of temperature and relative humidity from Cross track Infrared Sounder (CrIS) onboard Suomi-NPP, through integration of five different methods.
