The Microwave Radiation Imager (MWRI) loaded on the Chinese FengYun-3B (FY-3B) satellite is gradually used in the global environment research through November  2011. In this paper  we proposed a snow depth retrieval algorithm to estimate snow depth in Northeast China using MWRI passive microwave remote sensing data. A decision tree method of snow identification was firstly designed to distinguish different snow cover conditions in order to eliminate other interference signals. After using the proposed decision tree method  the processing results were further used to retrieve the snow depth in Northeast China. Finally  the practical snow depth data and the MODIS data were collected for the accuracy assessment of the proposed snow depth retrieval method. The experimental results demonstrated that the RMSE of snow depth used the proposed method was approximately 3 cm in Northeast China. 2012 SPIE.   SIMULATION OF EMISSION PROPERTIES AND SNOW-SOIL SYSTEM STATUS OF A MELTING THIN SNOW PACK 会议论文  OAI收割 2011 Ieee International Geoscience and Remote Sensing Symposium, New York Pan, Jinmei; Jiang, Lingmei; Zhang, Lixin; Zhao, Shaojie; Wang, Pei; Hao, Zhenguo; Xiao, Lijiao; Zhao, Tianjie; Wu, Fengmin 收藏  |  浏览/下载：41/0  |  提交时间：2014/12/07 Wet snow  HUT model  SNTHERM model  passive microwave  WATER EQUIVALENT RETRIEVAL  BEHAVIOR  MODEL
