A global satellite environmental data record derived from AMSR-E and AMSR2 microwave Earth observations
Spaceborne microwave remote sensing is widely used to monitor global environmental changes for understanding hydrological, ecological, and climate processes. A new global land parameter data record (LPDR) was generated using similar calibrated, multifrequency brightness temperature (Tb) retrievals from the Advanced Microwave Scanning Radiometer for EOS (AMSR-E) and the Advanced Microwave Scanni...
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 کاملInter-Calibration of Satellite Passive Microwave Land Observations from AMSR-E and AMSR2 Using Overlapping FY3B-MWRI Sensor Measurements
The development and continuity of consistent long-term data records from similar overlapping satellite observations is critical for global monitoring and environmental change assessments. We developed an empirical approach for inter-calibration of satellite microwave brightness temperature (Tb) records over land from the Advanced Microwave Scanning Radiometer for EOS (AMSR-E) and Microwave Scan...
متن کاملAn Improved Land Surface Emissivity Parameter for Land Surface Models Using Global Remote Sensing Observations
Because land surface emissivity ( ) has not been reliably measured, global climate model (GCM) land surface schemes conventionally set this parameter as simply constant, for example, 1 as in the National Oceanic and Atmospheric Administration (NOAA) National Centers for Environmental Prediction (NCEP) model, and 0.96 for bare soil as in the National Center for Atmospheric Research (NCAR) Commun...
متن کاملThe sensitivity of land emissivity estimates from AMSR-E at C and X bands to surface properties
Microwave observations at low frequencies exhibit more sensitivity to surface and subsurface properties with little interference from the atmosphere. The objective of this study is to develop a global land emissivity product using passive microwave observations from the Advanced Microwave Scanning Radiometer – Earth Observing System (AMSR-E) and to investigate its sensitivity to land surface pr...
