**4. Conclusions**

The joint use of agrometeorological stations and the MODIS MOD13Q1 reflectance product allowed the large-scale energy balance quantification and analyses in the mixed agroecosystems composed by sugarcane, coffee, and natural vegetation along the year 2015 in the northeastern side of São Paulo state, Southeast Brazil. The strong dependence of net radiation (Rn) on the global solar radiation (RG) levels was clear for all classes, however, being lower for sugarcane and higher for coffee.

The daily values for the latent (λE), sensible (H), and ground (G) heat fluxes can be estimated in different kinds of vegetation from instantaneous measurements of the reflectances from the MODIS sensor, throughout the application of the SAFER algorithm. The lowest and the highest λE were, respectively, for sugarcane and coffee. Although sugarcane presents lower evapotranspiration rates than coffee crop in an annual scale, being a positive aspect under the actual water scarcity conditions, its higher H has to be considered under the conditions of the coupled effects of warming and land use changes.
