Using in-situ measurements of canopy light-use efficiency (LUE) and leaf chlorophyll content collected at several flux tower sites across the U.S., evaluate functional relationship developed at BARC OPE3 and Bushland TX ARS experiment sites. This relationship will be embedded into a remote sensing model of vegetation canopy radiative transfer and use to map LUE at several flux sites within the U.S. using high resolution remote sensing inputs. These remotely sensed LUE maps will bed input into a model that maps coupled carbon, water and energy fluxes at multiple spatial and temporal scales using thermal-band imagery from the MODIS (1km daily) and Landsat (30m 16-day) satellites. The STARFM data fusion algorithm will be used to fuse MODIS/Landsat flux maps to generate daily flux maps at 30m (sub-field) spatial resolution. Daily flux predictions of evapotranspiration and canopy carbon uptake will then be evaluated in comparison with flux tower observations.
