Dr. Carsten Pathe received the Dipl.Geogr. degree from the Friedrich Schiller Univ. of Jena, Germany, in 2002 and Ph.D. in 2009 from the Vienna Univ. of Technology, Austria for his research on soil moisture retrieval from multi-year Envisat ASAR ScanSAR data using a change detection technique. From 2002 to 2010 he worked as a project assistant and manager at the Institute of Photogrammetry and Remote Sensing (I.P.F.) at the Vienna Univ. of Technology. Since 2010 he is with the chair of remote sensing at the Institute of Geography at the Friedrich-Schiller University Jena, Germany. His main tasks comprise the development and application of methods for retrieving geophysical variables over land from active remote sensing data with a particularly interest in soil moisture and biomass. He has been involved in several national and international research projects working on establishing operational methods for extracting geophysical variables active microwave sensors.
