Snow Grain and Snow Fraction Retrieval Algorithms based on Asymptotic Radiative Transfer Model

Wang Jie;Li Weipeng;College of Land and Resources,China West Normal University;  
Asymptotic Radiative Transfer(ART)model had been widely applied to pure snow grains sizes retrieval,but the model neglected the effect of mixed pixels.In the study we extended ART model to mixed pixels.In order to obtain snow grain and snow cover fraction,two kind unmixing algorithms were used.One algorithm used the non-constrained least square method of MODSCAG model to obtain snow grain sizes for each pixel,and Full Constrained Least Square(FCLS)unmixing algorithm was used to reverse the snow cover fraction for each pixel.The other algorithm used Generalized Reduced Gradient(GRG)algorithm to decompose each pixel,and snow grain sizes and snow cover fraction were obtained simultaneously.Before unmixing image,ART model was used to build a snow reflectance spectral library with different snow grain sizes,meanwhile,vegetation library(selected from image)and soil library(selected from Hopkins university spectral library)were used.In order to compare the retrieval accuracy for snow grain sizes and snow cover fraction,single channel ART snow grains retrieval algorithm(which is called as Zege model)and MODSCAG model were used.The experimental results showed that the retrieval results of two algorithms had higher accuracy than MODSCAG model.
