Interferometric baseline plays a very important role in InSAR data processing, and it will directly affect the accuracy of interferometric result. In this article, three classical baseline estimation methods were described. By comparing and combining three methods, a new baseline estimation method and its flow were listed. RADARSAT-2 satellite image data and grid digital elevation model ASTER GDEM...
A comprehensive validation method of remotely sensed evapotranspiration (ET) was proposed in this paper. Among this method, an observation system was constituted of an eddy covariance system, a large aperture scintillometer and an automatic weather station, and then an observation network was established at Miyun, Guantao, Daxing, Xiaotangshan, and Haidian Park sites in Hai River Basin, which were...
Recently, simple methods for real-time surface dryness estimation - perpendicular drought indices based on red and near-infrared wavelengths of satellite data has been developed. In this paper, the normalized form of the method is proposed to assess droughts over U.S. great plains using long term records of the Advanced Very High Resolution Radiometer (AVHRR) from both Land Long Term Data Record (LTDR)...
