Abstract

Given the significant importance of the surface processes, especially the fluxes of energy, mass and momentum, in the interaction with the planetary boundary layer, the formation of cumulus clouds and the development of meso-scale systems, it is intended to quantify by means of micrometeorological measurements the energy balance above areas of vegetation predominant in the State of São Paulo (sugarcane, pasture and maize). In addition to the understanding itself of the relationship between the phenological cycle and the dynamic of water vapor, carbon and energy in these ecosystems, the observational data will be used in the calibration of biosphere-atmosphere coupled models (SiB-RAMS), a tool to be used in the study of the impact of different types of soil-vegetation system in the numerical simulation of the atmosphere above the Southeast region. The calibration is equally viable for the validation of large scale models, such as, for example, the CPTEC / INPE model. (AU)
