Brightness Temperature Computation of Microwave Calibration Targets [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 2017 A rigorous numerical technique to compute the brightness temperature of arbitrarily shaped microwave calibration targets is presented. The proposed method allows the brightness temperature of calibration targets to be investigated depending on frequency, absorber material, geometry, antenna pattern, field incidence, and temperature environment. We have

Addendum to: The brightness temperature of Mercury at 150 and 240 GHz
The European Physical Journal Plus, 2012 We present new measurements of Mars at 1.25 and 2mm of wavelength, in addition to the previous ones performed on Mercury and already published in our paper “The brightness temperature of Mercury at 150 and 240GHz”. A brief description of the observational strategy is given, and brightness temperature of the planet is reported.

Venus: A Map of Its Brightness Temperature
Science, 1963 The 200-inch Hale telescope has been used to make high-resolution maps of the brightness temperature of Venus at wavelengths 8 to 14 microns. Resolution of about 1/30 of the disk reveals a general symmetry about the plane of the orbit, no day-night temperature effects, and a transient temperature anomaly in the southern hemisphere.

Land Surface Brightness Temperature Modeling Using Solar Insolation
IEEE Transactions on Geoscience and Remote Sensing, 2010 Retrieval of land surface emissivity and temperature from microwave brightness temperature data is a complex problem. The diurnal variation of temperature due to the diurnal cycle of solar radiation and weather conditions makes this problem even more ...

Brightness Temperature Reconstruction Using BGI
IEEE Transactions on Geoscience and Remote Sensing, 2008This paper departs from the popular usage of the Backus-Gilbert inversion (BGI) method as a tool for inversion of antenna temperature measurements in microwave radiometry. The BGI method is applied in this paper to enhance the information content of an existing set of oversampled brightness-temperature (TB) data. The purpose is to isolate the inversion

Cloud Model Studies for the Simulation of Brightness Temperatures
2006 IEEE International Symposium on Geoscience and Remote Sensing, 2006Two cloud water models that can be included in the radiative transfer to simulate brightness temperatures from radiosonde data are analyzed. We first evaluate and optimize the capability of the models to detect correctly the presence of clouds, by comparing the cloud base heights identified from the radiosoundings with those provided by a ceilometer ...
