Sensitivity of Land Covers on Passive Microwave Brightness Temperature
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019Obvious increased microwave brightness temperature has been observed around the epicenters before strong earthquakes. It can be looked as a potential signal for thermal anomalies related to earthquake activities. However, passive microwave observation can be affected by many environmental factors, such as soil moisture, vegetation cover, surface ...

Lunar regolith thermal behavior revealed by Chang'E-1 microwave brightness temperature data
Earth and Planetary Science Letters, 2010 Microwave brightness temperature data obtained by the Chinese Chang'E-1 lunar orbiter are analyzed with the lunar diurnal variations filtered. Resulting maps from the high frequency microwave channel show lunar topographic signatures with close ...

Influence of microphysical cloud parameterizations on microwave brightness temperatures
IEEE Transactions on Geoscience and Remote Sensing, 2002The microphysical parameterization of clouds and rain cells plays a central role in atmospheric forward radiative transfer models used in calculating microwave brightness temperatures. The absorption and scattering properties of a hydrometeor-laden atmosphere are governed by particle phase, size distribution, aggregate density, shape, and dielectric ...

An approximate model for the microwave brightness temperature of the sea
International Journal of Remote Sensing, 1987Abstract A modified two-scale model is proposed for scattering and emissivity calculations for certain classes of random rough surfaces. It is based on an approach by Burrows and by Brown, but it has been extended to bistatic scattering by lossy dielectric surfaces, and it incorporates modified Fresnel reflection coefficients and a simple correction ...

A Global Analysis of Passive Microwave Brightness Temperature Diurnal Cycle
IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020Passive microwave brightness temperature (TB) radiometers are widely used to retrieve several atmospheric and surface parameters such as precipitation, soil moisture, freeze and thaw, water vapor, air temperature profile, and land surface emissivity.

Microwave brightness temperatures of the greenland ice sheet
Advances in Space Research, 1989Abstract Microwave brightness temperatures measured by the Scanning Multichannel Microwave Radiometer on NIMBUS-7 over the Greenland ice sheet are analyzed for temporal, spatial, and frequency and polarization variations. Two periods are investigated, November 1978 to October 1980 and January to March 1982, i.e.

Spatial Correlation Patterns of L-Band Microwave Brightness Temperature
IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008Incorporating the spatial correlation information into the land data assimilation system provides the opportunities to improve the analysis quality of the assimilation system. In order to make use of the spatial autocorrelation information effectively in the land data assimilation system, we used the geostatistics to explore and describe the spatial ...

Microwave brightness temperature variations caused by ocean internal waves
IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004Oceanic internal waves were observed by microwave radiometers from a blimp during the COPE'99 experiment. Brightness temperature variations caused by sea surface roughness modulation and enhanced wave breaking were compared with model calculations. It is shown that direct wave amplitude modulation by currents cannot explain the observed brightness ...

Model for atmospheric corrections to microwave brightness temperature data
Remote Sensing of Environment, 1983Abstract The effects of atmospheric liquid water (cloud) and water vapor on the brightness temperature data acquired by Bhaskara-Satellite Microwave Radiometer at 19.1 and 22.235 GHz near the nadir look angle have been discussed in detail. It has been observed that the net contribution to brightness temperature data due to atmosphere is quite ...

Comparison of microwave brightness temperatures and radar reflectivity measurements
SPIE Proceedings, 1994Satellite-sensor based microwave brightness temperatures are compared with radar based reflectivities for a three-dimensional mining cloud. The brightness temperatures are computed using a radiative transfer model based on the discrete-ordinates method.
