| 英文简介 | Changes of snow grain size and pollutants over snow cover may result in strong fluctuation of snow albedo, subsequently have feedback effects on the climate system and affect the hydrological processes. Focusing on snow grain size and pollutants, the following research would be carried out: 1) exploring the influence of snow grain size and pollutants (black carbon and dust) on bidirectional reflectance of snow, by analyzing measured snow data from the experiments which would be conducted on various snow cover types (snow grain size and pollutants) ; 2) developing a new snow radiative transfer model based on experimental measurements and Asymptotic RadiativeTransfer model (ART), which can simultaneously simulate snow grain, black carbon and dust; 3) on scale of subpixel, coupling the new snow radiative transfer model and Fully Constrained Least Squares-Linear Spectral Mixture Model (FCLS-LSMM, and subsequently developing an intergrated retrieval model including retrievals of snow area proportion, snow grain size , black carton as well as dust; 4) producing the retrieval products of snow area proportion, snow grain size, contents of black carton and dust over north Xinjiang province based on MODIS and MERSI, assessing the accuracy of these products. This project will enhance and improve the methods of quantitative remote sensing of snow, meanwhile provide richer and more reliable inputting data for hydrological and atmospheric models. Our research is also promising. |
