Research Project: A Unified and Coherent Land Surface Temperature and Emissivity (LST&E) Earth System Data Record (ESDR) for Earth Science

Location: Hydrology and Remote Sensing Laboratory

Project Number: 8042-13610-029-71-I
Project Type: Interagency Reimbursable Agreement

Start Date: Apr 15, 2014
End Date: Feb 26, 2019

To evaluate performance of an existing method for mapping evapotranspiration and drought using a new, improved satellite-based land-surface temperature Earth System Data Record (ESDR).

USDA-ARS will apply a remote sensing algorithm for mapping evapotranspiration (ET) and drought to a geostationary satellite ESDR to be developed under this project. ESDR improvements over existing land-surface temperature products include improved specification of surface emissivity and cross-calibration using polar orbiting satellite data. ET estimates will be compared with observations on the ground using eddy covariance (EC) flux equipment to evaluate mapping accuracy. Drought assessments from the improved ESDR will be compared with drought classifications from the North American Drought Monitor and standard drought indices.
