SCALING UP EQUIVALENT WATER THICKNESS IN SAVANNA ENVIRONMENTS: FROM LOCAL TO BIOME SCALE, VIA GROUND, HYPERION, AND MODIS DATA

摘要

Within the scope of the NASA LCLUC sponsored project "Interactions of Edaphic and Land-Use Factors on Water Resources of the Cerrado Region of Brazil ", focused on understanding and quantifying the impacts and feedbacks of current and future land cover changes on the Cerrado hydrology, canopy water content based on the Earth Observing-1 (EO-1) Hyperion satellite imagery has been successfully derived for different Cerrado physiognomies. In this paper, we describe an empirical approach for the regional extrapolation of these ground-truthed observations based on the Terra MODIS sensor.
