Atmosphere-Land Exchange Inverse model

Atmosphere-Land Exchange Inverse model (ALEXI)  is a multi-sensor TIR approach to ET mapping, coupling a two-source (soil+canopy) land-surface model with an atmospheric boundary layer model in time-differencing mode to routinely and robustly map daily fluxes at continental scales and 5 to10-km resolution using thermal band imagery and insolation estimates from geostationary satellites.
