Downward surface shortwave radiation (DSSR) is influenced by the atmosphere and mountainous topography. DEM scale is the key factor to affect the spatial distribution of DSSR in mode scale. In this paper, sensitivity of estimating DSSR to DEM scale is explored with six DEMs resolutions from 5-to 500-m based on our mountainous radiation algorithm published. According to the difference between the model...
Multiple InSAR techniques are increasingly being developed for earth observation. However, among them, persistent scatterers-based InSAR (PSI) techniques fail to obtain enough measurement points (MPs) in rural mountainous area due to the lack of persistent scatterers (PSs), such as ma-made structures, rocks, and outcrops, etc. In this paper, Distributed Scatterers-based InSAR (DS-InSAR) algorithm,...
