Satellite-Based Energy Balance for Mapping Evapotranspiration with Internalized Calibration (METRIC)—Model
Richard G. Allen,Richard G. Allen,Masahiro Tasumi,Masahiro Tasumi,Ricardo Trezza,Ricardo Trezza +5 more
TL;DR: METRIC uses as its foundation the pioneering SEBAL energy balance process developed in The Netherlands by Bastiaanssen, where the near-surface temperature gradients are an indexed function of radiometric surface temperature, thereby eliminating the need for absolutely accurate surface temperature and theneed for air-temperature measurements.
