The NASA-CASA model is being compared to measurements of energy, water, and carbon exchange at Tapajós National Forest (TNF) tower sites. Daily and monthly model estimates of plant water flux and soil water content, ecosystem productivity, biogeochemical processes, trace gas emissions, and net carbon sequestration are evaluated here for prediction errors and seasonal trends. High resolution (< 1-km) land cover images for 'footprint' areas of LBA tower sites are being used to define ecosystem model estimates and validation of predictions against measured tower fluxes of carbon and water exchange. Potential linkages to field measurements of aqueous carbon export from the TNF watershed are presented.
