%K slash and burn, albedo, net radiation, soil heat flux, "Terra Firme" forest, Amazon.
%X Forest clearing and subsequent burning of the downed biomass are parts of the occupation process in the Amazon region. This causes a clear impact on the, environment, including effects on the weather and the climate. Thus, campaigns with controlled burnings wereeftected in clearings of virgin "Terra Firme" Amazonian Forest in the Alta Floresta, MT region of Brazil (Fazenda Caiabi), to assess the combustion process and some of its consequences. These clearings were cut, allowed to dry and then burnt using the local traditional method.This work presents the evolution of components of the energy balance (net radiation and soil heat flux) plus albedo measured continuously (DOY 150 to 330) in the 200 x 200 m2 site centered at 9°57'42.20" S and 56°20'52.05" W. The site was downed on May 26, 1999 (DOY 146), after 15 days of work, and its burning was eftected on August 24, 1999 (DOY 236), starting at 11 :35 LST.
