The Global Satellite Mapping of Precipitation product (GSMaP)[1], is a recent solution of satellite-based precipitation estimates which provides global rainfall products of high spatial (0.1°) and temporal resolutions (1 hour). This paper presents a study of GSMaP precipitation products (GSMaP_MVK and GSMaP_Gauge) for a torrential precipitation event in Jinghe Basin (from 06:00 AM on 22 July 2010...
With emphasis on physics-based techniques, a multi-objective optimization approach to combined radar-radiometer soil moisture estimation is presented in this work. Soil moisture estimation is demonstrated via application of this method to SMAP high resolution radar and coarse resolution radiometer data. Comparisons are then made with the SMAP baseline active-passive soil moisture output data product...
The output signal of millimeter-wave (MMW) radiometer is usually affected by 1/f-noise that is characterized by self-similarity and non-stationary. Wavelet thresholding techniques are widely used to de-noise. However, soft-thresholding has good de-noising effect but is poor in details preservation, and hard-thresholding is good in details preservation but has poor de-noising effect. To eliminate 1/f-noise...
