Tropical Cyclone Intensity and Position Analysis Using Passive Microwave Imager and Sounder Data
Satellite based Tropical Cyclone (TC) intensity estimates are critical for TC warning centers and global Numerical Weather Prediction (NWP) Models due to the lack of in-situ observations of mean sea-level pressure and TC winds. Passive microwave instruments on polar-orbiting weather satellites are u...
