Resumo Inglês:
The global climate is directly dependent on the ecological balance of forests, especially tropical ones. The heat flux in the soil is an important factor in studies of energy balance representing the main form of energy exchange between soil and atmosphere. The aim of the present work was to estimate soil heat flux using soil temperature measurements at two depth levels in a tropical forest in the Western Amazon, in order to obtain coherent data for both the use of the values and for the filling of failures in database. Soil temperature and heat flux data collected in a micrometeorological tower belonging to the tower network of the Large Scale Biosphere-Atmosphere Program in the Amazon region, located in the Jaru Biological Reserve, were used. The estimated data presented 94% of agreement with the measured data, the two have similar behaviors that allow the use in filling of demonstrative failures. However, there is a delay in the estimated values of the heat flux in the soil in relation to the measured one, which interferes in the result of the model, provoking more studies to improve it.
