Land surface models (LSMs) are typically forced with observed precipitation and meteorology hence the soil moisture estimates obtained from LSM do not reflect contribution of irrigation to estimates. However, satellite retrievals register signature effects. It is suggested that may role if they assimilated estimated satellites. The present study evaluates improvement Noah by ingesting them sate...

RESUME Over the last years, the Institute of Photogrammetry and Remote Sensing (I.P.F., Vienna University of Technology) has been putting in practice the retrieval of soil moisture from ERS scatterometer data. Anticipating the operational and partly near-real time creation of soil moisture products based on the existent ERS methods applied to the upcoming ASCAT scatterometer data, we evaluate t...

Surface soil moisture is one of the operational products derived from Advanced Scatterometer (ASCAT) data. The reliability of its estimation depends on the detection of predominantly frozen conditions of the landscape (including soil and vegetation) and the presence of wet snow, which would otherwise impede the estimation. As the robust determination of the freeze/thaw (F/T) state using exclusi...

Sea Ice Mapping Using Enhanced Resolution Advanced Scatterometer Images Steven Reeves Department of Electrical and Computer Engineering Master of Science Sea ice is of great interest due to its effect on the global climate, the Earth’s ecosystem, and human activities. Microwave remote sensing has proven to be an effective way to measure many of the characteristics of sea ice. In particular, sev...

This study examines the impacts of assimilating ocean-surface winds derived from NASA Cyclone Global Navigation Satellite System (CYGNSS) on improving short-range numerical simulations and forecasts landfalling hurricanes using NCEP operational Hurricane Weather Research Forecasting (HWRF) model. A series data assimilation experiments are performed HWRF a Gridpoint Statistical Interpolation (GS...
