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.   Correlated observations of intensified whistler waves and electron acceleration around the geostationary orbit 期刊论文 plasma physics and controlled fusion, 2012 Xiao, Fuliang; Zong, Qiugang; Su, Zhenpeng; He, Zhaoguo; Wang, Chengrui; Tang, Lijun 收藏  |  浏览/下载：2/0  |  提交时间：2015/11/16 OUTER-ZONE ELECTRONS  RELATIVISTIC ELECTRONS  RADIATION BELT  MODE CHORUS  RESONANT DIFFUSION  MAGNETOSPHERE  FLUXES  STORM  ENERGIZATION  NOVEMBER   Discussion on the nucleation rate of ferrite during continuous cooling in a lowcarbon steel measured by 3DXRD 会议论文 Solid-Solid Phase Transformations in Inorganic Materials 2005, Vol 1, International Conference on Solid-Solid Phase Transformations in Inorganic Materials (PTM 2005), Phoenix, AZ, Web of Science Yang, Zhi-Gang; Enomoto, M. 收藏  |  浏览/下载：4/0 The optical spectral slope variability of 17 blazars 期刊论文 Monthly notices of the Royal Astronomical Society, 2006, 卷号: 371, 期号: 3, 页码: 1243-1250 作者:  Hu SM;  Zhao G;  Guo HY;  Zhang X;  Zheng YG 收藏  |  浏览/下载：1/0  |  提交时间：2020/01/03 galaxies : active  BL Lacertae objects : general  galaxies : fundamental parameters  quasars : general  BL-LACERTAE OBJECTS  EXTRAGALACTIC RADIO-SOURCES  ACTIVE GALACTIC NUCLEI  RAY LOUD BLAZARS  S5 0716+714  MULTIFREQUENCY OBSERVATIONS  LAC OBJECTS  INTRADAY VARIABILITY  ENERGY-DISTRIBUTIONS  NOVEMBER 1995   Ring current oxygen ions escaping into the magnetosheath 期刊论文 journal of geophysical research space physics, 2001 Zong, QG; Wilken, B; Fu, SY; Fritz, TA; Korth, A; Hasebe, N; Williams, J; Pu, ZY 收藏  |  浏览/下载：6/0  |  提交时间：2015/11/11 EARTHS BOW SHOCK  SOLAR-WIND  DAYSIDE MAGNETOSHEATH  GEOTAIL OBSERVATIONS  MAGNETOSPHERIC IONS  ENERGETIC PARTICLES  NOVEMBER 1  UPSTREAM  FIELD  MAGNETOPAUSE
