Jeu, Richard A.M. (author), Wagner, W. (author), Holmes, T. R.H. (author), Dolman, A. J. (author), van de Giesen, N.C. (author), Friesen, J (author)Within the scope of the upcoming launch of a new water related satellite mission (SMOS) a global evaluation study was performed on two available global soil moisture products. ERS scatterometer surface wetness data was compared to AMSR-E soil moisture data. This study pointed out a strong similarity between both products in sparse to moderate...journal article 2008

Hahn, Sebastian (author), Wagner, Wolfgang (author), Steele-Dunne, S.C. (author), Vreugdenhil, M. (author), Melzer, Thomas (author)This study investigates the performance of the TU Wien soil moisture retrieval (TUW-SMR) algorithm by adapting the strength of the vegetation correction. The semiempirical change detection method TUW-SMR exploits the multiangle backscatter observations from spaceborne fan-beam scatterometer systems in order to derive surface soil moisture...journal article 2020

Steele-Dunne, S.C. (author), Hahn, Sebastian (author), Wagner, Wolfgang (author), Vreugdenhil, M. (author)The TU Wien Soil Moisture Retrieval (TUW SMR) approach is used to produce several operational soil moisture products from the Advanced Scatterometer (ASCAT) on the Metop series of satellites as part of the EUMETSAT Satellite Application Facility on Support to Operational Hydrology and Water Management (H SAF). The incidence angle dependence...journal article 2021

Vreugdenhil, Mariette (author), Greimeister-Pfeil, Isabella (author), Preimesberger, Wolfgang (author), Camici, Stefania (author), Dorigo, Wouter (author), Enenkel, Markus (author), van der Schalie, Robin (author), Steele-Dunne, S.C. (author), Wagner, Wolfgang (author)Agricultural droughts are extreme events which are often a result of interplays between multiple hydro-meteorological processes. Therefore, assessing drought occurrence, extent, duration and intensity is complex and requires the combined use of multiple variables, such as temperature, rainfall, soil moisture (SM) and vegetation state. The...review 2022
