The snowmelt runoff model (SRM) is used to simulate streamflow from snowmelt in the Er'dao-Songhua basin of upper Songhuajiang basin from March to August in 2010. The basin is divided into three elevation zones based on SRTM DEM data. MODIS flexible snow cover products (MODISMC) are generated form daily Terra/Aqua products and used as snow cover area input for SRM model. The precipitation and temperature...
High-resolution (HR) satellite images have been more and more applied to large-scale mapping; however, due to lack of RFM parameters or nature of high-order RPC model, the solutions occasionally fail. Based on a strict imaging model proposed by Weser, this paper, by adopting different functions to correct orbits and attitudes, analyze effects caused by sources of errors. Besides, because of invariant...
When the conventional method of parameter estimation is used to construct the RPC model, the uncertain factors can result in inconsistency between the RPC model and the reality. The inconsistency shows up as evident systematic error in the constructed RPC model. To tackle the problem, a non-parametric component is introduced on the base of the parametric model to account for the unknown factors and...
Based on PWV (Precipitable Water Vapor) data from the ground-based GPS (Global Positioning System), weather station's ground data and NCEP grid reanalysis dataset, the transport process of water vapor during the “7.17” heavy rainfall in Chongqing of 2007 is studied. The important role of remote sensing water vapor of the ground-based GPS (precipitable water vapor) is analyzed. It is shown that the...
