Petchiappan, A. (author), Steele-Dunne, S.C. (author), Vreugdenhil, M. (author), Hahn, S. (author), Wagner, W. (author), Oliveira, R. (author)Microwave observations are sensitive to plant water content and could therefore provide essential information on biomass and plant water status in ecological and agricultural applications. The combined data record of the C-band scatterometers on the European Remote-Sensing Satellites (ERS)-1/2, the Metop (Meteorological Operational satellite)...journal article 2022

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

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, M. (author), Navacchi, Claudio (author), Bauer-Marschallinger, Bernhard (author), Hahn, Sebastian (author), Steele-Dunne, S.C. (author), Pfeil, Isabella (author), Dorigo, Wouter (author), Wagner, Wolfgang (author)Vegetation products based on microwave remote sensing observations, such as Vegetation Optical Depth (VOD), are increasingly used in a variety of applications. One disadvantage is the often coarse spatial resolution of tens of kilometers of products retrieved from microwave observations from spaceborne radiometers and scatterometers. This can...journal article 2020

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
