Microwave radiometer measurements are used to extract snowpack information. However, the coarse spatial resolution of satellite brightness temperature observations hinders snow depth retrieval algorithm development and other applications. Measurements therefore require better spatial resolution to improve snow depth retrieval with enhanced resolution and accuracy. In this paper, a linear unmixing...
This paper presented a pixel-based statistical regression method based on a high-resolution snow depth product to improve the accuracy of passive microwave snow depth retrievals. The statistical regression relation was established based on a linear relationship between the snow depth and the brightness temperature (TB) difference. The coefficients of these regression equations were derived using the...
The coarse spatial resolution of microwave radiometer measurements hinders its application on land and sea surface parameters estimation. Measurements therefore require better spatial resolution to improve parameters estimation with enhanced resolution and accuracy. In this paper, a linear unmixing method is presented to downscale brightness temperatures (TB) for accurate land surface parameters retrieval...
