A Parameterized Microwave Emissivity Model for Bare Soil Surfaces
Due to the difficulty in accurately interpreting surface emissivity spectra, problems remain in the application of passive microwave satellite observations over land surfaces. This study develops a parameterized soil surface emissivity model to quantify the microwave emissivity accurately and rapidly for Gaussian-correlated rough surfaces. We first analyze the sensitivity of surface emissivity ...

متن کاملDevelopment of Global Land Surface Emissivity Map at Amsr-e Passive Microwave Frequencies
Microwave emissivity over ocean is relatively well understood by scientists. However, over land because of the existence of different land covers and their various physical properties land surface emissivity retrieval does not seem to be straightforward. Land emissivity plays a key role in Numerical Weather Prediction (NWP) models, since it acts like a crucial boundary condition. The accuracy o...
متن کاملAssessment of the consistency among global microwave land surface emissivity products
The goal of this work is to intercompare four global land surface emissivity products over various landcover conditions to assess their consistency. The intercompared land emissivity products were generated over a 5year period (2003–2007) using observations from the Advanced Microwave Scanning Radiometer – Earth Observing System (AMSR-E), the Special Sensor Microwave Imager (SSM/I), the Tropica...
