emissivity mapping of the earth’s surface is the prerequisite to thermal remote sensing. a precise determinationof a surface's temperature is dependent upon the availability of precise emissivity data for that surface. the presentstudy area is a part of sugarcane plantation fields in the west part of khuzestan province. in this work, temperatureemissivity separation algorithm (tes) was applied ...

There are three popular methods to understand the land subsidence: leveling, Global Navigation Satellite System, and Interferometric Synthetic Aperture Radar (InSAR) analysis using SAR images. While both leveling System can measure amount of subsidence only at specific points, InSAR observe a wide area in short time intervals. In terms accuracy, however, is inferior leveling; centimeter/millime...

This study developed a coupled land–atmosphere satellite data assimilation system as a new physical downscaling approach, by coupling a mesoscale atmospheric model with a land data assimilation system (LDAS). The LDAS consists of a land surface scheme as the model operator, a radiative transfer model as the observation operator, and the simulated annealing method for minimizing the difference b...

Using satellite measurements in microwave bands to retrieve precipitation over land requires proper discrimination of the weak rainfall signals from strong and highly variable background Earth surface emissions. Traditionally, land retrieval methods rely on a weak signal of rainfall scattering on high-frequency channels and make use of empirical thresholding and regression-based techniques. Bec...
