B. S. da  aEnergy balance model applied to pasture experimental areas in São Paulo State, Brazil.h[electronic resource]  c2016  aThe Simple Algorithm for Evapotranspiration Retrieving (SAFER) was used to estimate biophysical parameters and theenergy balance components in two different pasture experimental areas, in the São Paulo state, Brazil. The experimentalpastures consist in six rotational (RGS) and three continuous grazing systems (CGS) paddocks. Landsat-8 images from2013 and 2015 dry and rainy seasons were used, as these presented similar hydrological cycle, with 1,600 mm and 1,613mm of annual precipitation, resulting in 19 cloud-free images. Bands 1 to 7 and thermal bands 10 and 11 were used withweather data from a station located nearthe experimental area. NDVI, biomass, evapotranspiration and latent heat flux(λE) temporal values statistically differ CGS from RGS areas. Grazing systems influences the energy partition and theseresults indicate that RGS benefits biomass production, evapotranspiration and the microclimate, due higher LE values.SAFER is a feasible tool to estimate biophysical parameters and energy balance components in pasture and has potentialto discriminate continuous and rotation grazing systems in a temporal analysis.  aBiomass  aEvapotranspiration  aBiomassa  aEvapotranspiração  aPastagem  aSistema de pastejo  aFluxo de calor do solo  aFluxo de calor latente  aFluxo de calor sensível  aGrazing systems  aLatent heat flux  aPasture  aSAFER  aSensible heat flux  aSoil heat flux1 aTEIXEIRA, A.
