A very large data set of AMSR-E data collected over Siberia was also analyzed. By using a simplified algorithm, the SD was estimated using both frequency and polarization indexes and global maps of SD were generated over Europe.","PeriodicalId":122743,"journal":{"name":"2012 12th Specialist Meeting on Microwave Radiometry and Remote Sensing of the Environment (MicroRad)","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116057199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several previous works demonstrated that an increase of soil moisture is associated to a decrease of e and a corresponding increase of σ°. Other surface variables, such as soil roughness and vegetation biomass also influence both e and σ°, but in a different way with respect to soil moisture. In a previous paper, it was assumed that an ideal triangle can be traced on the e-σ° plane, with vertexes corresponding to dry soil, wet soil and dense vegetation conditions, respectively. In this paper, this assumption is tested using passive and active signatures collected by SMOS and ALOS-PALSAR instruments, respectively, over various kinds of surfaces.","PeriodicalId":122743,"journal":{"name":"2012 12th Specialist Meeting on Microwave Radiometry and Remote Sensing of the Environment (MicroRad)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124277750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
