An Enhanced Resolution Brightness Temperature Product for Future Conical Scanning Microwave Radiometers [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 2022 An enhanced spatial resolution brightness temperature product is proposed for future conical scan microwave radiometers. The technique is developed for Copernicus Imaging Microwave Radiometer (CIMR) measurements that are simulated using the CIMR antenna pattern at the L-band and the measurement geometry proposed in the Phase A study led by Airbus.

Temporal variations of microwave brightness temperatures over Antarctica [PDF]
Annals of Glaciology, 1994 Passive microwave brightness temperatures from the Special Sensor Microwave Imager (SSMI) are studied together with surface air temperatures from two Automatic Weather Stations (AWS) for the year 1989. One station is located on the East Antarctic plateau (Dome C) and the other on the Ross lee Shelf (Lettau).The satellite data for frequencies 19, 22 and

Microwave Brightness Temperatures from Tilted Convective Systems [PDF]
Journal of Applied Meteorology, 2000 Aircraft and ground-based radar data from the Tropical Ocean and Global Atmosphere Coupled Ocean– Atmosphere Response Experiment show that convective systems are not always vertical. Instead, many are tilted from vertical.
