ETLook: a novel continental evapotranspiration algorithm

摘要

ETLook is a newly developed algorithm to compute the evapotranspiration of large areas using an array of remote sensing data: moderate resolution visible and near infrared data from the MODIS sensor, and low resolution estimates of soil moisture from the AMSRE sensor. The Penman-Monteith equation is solved separately for vegetation and soil, enabling the division of evapotranspiration into transpiration and evaporation. The ETLook algorithm has been applied in Australia, China and the Indus basin.
