The carbon balance over an area of Atlantic Rainforest with micrometeorological and biometrical measurements


To understand and quantify the patterns of productivity and functionality of tropical forests with respect to climate signifies increasing the predictability of the state of the ecosystems and of their environmental services. The projections of increase in temperature and variability of rainfall in South America in the coming decades point to scenarios which promote new states of equilibrium and areas of potential occupation of forest and cerrados, including the Atlantic Rainforest. This region does not have integrated hydroclimatic information and information on the carbon cycle obtained with modern techniques which make it possible to track the biophysical rhythms in progress with the potential changes in environment and climate. The micrometeorological approach to estimate the Liquid Flux of CO2 in the Ecosystem (FLE) is a sum of three contributions: the turbulent flux (or eddy covariance), the vertical nonturbulent flux (accumulation or removal of CO2) and the vertical and horizontal advective flux. In the areas of gentle topography the first two terms respond for the greater variance of the FLE, and in regions of valleys and mountains the estimate of the advective term is imperative. This proposal intends to study an area of the Atlantic Rainforest, in the Serra do Mar in SP, planned under a multidisciplinary investigation with high technical detailing, to implement a system for measuring advective atmospheric fluxes of CO2, in parallel with the measurement of variation in the stocks of carbon using biometrical techniques, taking advantage also of the data from a flux tower implemented in the thematic project Composition, structure and functioning of the forest in the Serra do Mar State Park.
