Downscaling microwave brightness temperatures using self regularized regressive models [PDF]
2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015 A novel algorithm is proposed to downscale microwave brightness temperatures ($\mathrm{T_B}$), at scales of 10-40 km such as those from the Soil Moisture Active Passive mission to a resolution meaningful for hydrological and agricultural applications. This algorithm, called Self-Regularized Regressive Models (SRRM), uses auxiliary variables correlated ...

The microwave brightness temperature spectrum of the quiet sun
The Astrophysical Journal, 1991 New measurements of the microwave brightness temperature spectrum of the center of the quiet sun, acquired at Owens Valley over several months during the 1986-1987 sunspot minimum, are reported. The resulting brightness temperature spectra are consistent with previous data, but exhibit much less frequency-to-frequency scatter. The corona is fitted well

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

Evidence of an increase in the microwave brightness temperature of Uranus
The Astrophysical Journal, 1978 Measurements are reported which indicate that the microwave brightness temperature of Uranus near 3 cm wavelength has increased by about 35% in the past decade. It is suggested that changes of this magnitude could be caused by seasonal or latitudinal variations of the microwave opacity of the Uranus atmosphere.

Modeling time series of microwave brightness temperature in Antarctica [PDF]
Journal of Glaciology, 2009 AbstractThis paper aims to interpret the temporal variations of microwave brightness temperature (at 19 and 37GHz and at vertical and horizontal polarizations) in Antarctica using a physically based snow dynamic and emission model (SDEM). SDEM predicts time series of top-of-atmosphere brightness temperature from widely available surface meteorological ...
