                         parameter in meteorological and plant growth-energy balance 
                         models. Thus, they were measured, together with soil moisture 
                         contents, within the LBA program at forest (Reserva Jaru) and 
                         pasture (Fazenda Nossa Senhora) sites in Rondonia, Brazilian 
                         Amazonia during wet (February) and dry (August) periods of 1999. 
                         The wet period showed maxima of the heat flux into the soil around 
                         five to six times smaller at the forest than at the pasture, 
                         except for some spikes that are related to stronger solar forcing, 
                         such as those due to sunspecks in the forest. This pattern 
                         remained during the dry period, but with doubled maximum values. 
                         Also, the soil heat flux and the soil temperatures responded very 
                         significantly to the passage of cold fronts in both periods at 
                         both sites. Temperature profiles measured in the 0.10-0.40 m soil 
                         layer showed daily averages and ranges smaller at the forest than 
                         at the pasture. The daily average of the soil moisture content in 
                         the same layer, during the wet season, increased with depth at 
                         both sites, with consistently lower values at the forest. However, 
                         their ranges were smaller at the pasture, except for the 0.40 m 
                         depth. During the dry period, these ranges were much higher at the 
                         pasture, but with nearer average values. Finally, the computed 
                         daily apparent soil thermal diffusivities, volumetric heat 
                         contents, and thermal conductivities are presented, with the first 
                         ones crossed with the measured soil moisture content.",
