Evolution of albedo, net radiation and soil heat flux before and after a forest burning in Southern Amazonia

.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 climate. Thus, campaigns with controlled burnings were effected in clearings of virgin "Terra Firme" Amazonian Forest in the Alta Floresta region of Brazil (9°57'S; 56°20'W) 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 during the 1999 campaign, covering the period since the cutting of the forest, until after the burning
