Using vegetation indices for soil-moisture retrievals from passive microwave radiometry
Surface soil moisture and the nature of the overlying vegetation both influence microwave emission from land surfaces significantly. One widely discussed but underused method for allowing for the effect of vegetation on soil-moisture retrievals from microwave observations is to use remotely sensed vegetation indices. This paper explores the potential for using the Normalised Difference Vegetati...
متن کاملAn Alternative Roughness Parameterization for Soil Moisture Retrievals from Passive Microwave Observations
The usefulness of L-band radiometer observations for the retrieval of near-surface soil moisture has already been demonstrated in many studies. Unfortunately, the ability to estimate soil moisture from these remotely sensed observations is hampered by the infeasibility to characterize the roughness of the soil surface. Given the difficulty to measure in situ soil roughness parameters, improved ...
متن کاملEnhancing Oceanic Retrievals using Microwave Radiometry
The Central Florida Remote Sensing Laboratory, CFRSL, of the School of Electrical Engineering and Computer Science at the University of Central Florida is engaged in research to improve passive microwave remote sensing techniques for inferring oceanic and atmospheric geophysical parameters. This paper presents an overview of research that falls into three major areas, namely; airborne hurricane...
متن کاملSpace-based passive microwave soil moisture retrievals and the correction for a dynamic open water fraction
The large observation footprint of low-frequency satellite microwave emissions complicates the interpretation of near-surface soil moisture retrievals. While the effect of sub-footprint lateral heterogeneity is relatively limited under unsaturated conditions, open water bodies (if not accounted for) cause a strong positive bias in the satellite-derived soil moisture retrieval. This bias is gene...
متن کاملThe added value of spaceborne passive microwave soil moisture retrievals for forecasting rainfall-runoff partitioning
[1] Using existing data sets of spaceborne soil moisture retrievals, streamflow and precipitation for 26 basins in the United States Southern Great Plains, a 5-year analysis is performed to quantify the value of soil moisture retrievals derived from the Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI) X-band (10.7 GHz) radiometer for forecasting storm event-scale runoff ratios....
