Methodology of spatialization of energy balance components using MODIS and ERA Interim data

This work aims at proposing a methodology to spatialize the Energy Balance (EB) components from combined use of MODIS sensor products and ERA-Interim reanalysis data, evaluate performance OSEB METRIC models for estimating EB in predominantly humid subtropical climate Rio Grande do Sul, Brazil. The research was conducted 3 consecutive years 2009 2011. temporal variation patterns were analyzed by comparing values estimated against reference measurements micrometeorological tower (Sulflux network). For spatial variability analysis, evapotranspiration (ETo) calculated local scale (data Weather stations National Institute Meteorology) regional (ERA-Interim data) while consistency between these estimates also verified. Afterward, using only pixels which sensible heat flux represented more than 50% radiation balance, correlation maps ETo latent fluxes constructed. BE are consistent regarding both, order magnitude throughout year, when compared tower. analyses reveal satisfactory results both models, however, model showed greater coherence since it provided number dates with results, thus being indicated as most suitable building time series.
