             abstract = "Reproducing the behavior of the mean variables that control the 
                         nocturnal atmospheric flow under very stable conditions is a very 
                         difficult task for atmospheric models. To understand the role of 
                         the surface scheme, turbulence scheme and radiation scheme on the 
                         performance of a single column model, its predictions are compared 
                         to observations collected at a very stable site located in 
                         deforested region in Amazon. The surface scheme takes on 
                         consideration the rapid changes in the surface energy budget 
                         caused by the presence of a vegetated layer over the soil. The 
                         turbulence scheme uses four different formulations for the mixing 
                         length. Two of them allow the existence of turbulence over the 
                         critical Richardson number, while the other two restrict 
                         dramatically the turbulence activity in those situations. The 
                         radiative scheme considers a clear sky condition, and evaluates 
                         the radiative flux divergence between 3 levels within the vertical 
                         domain: near the surface, at the domain top, and at the middle 
                         point between them. The predictions of all mixing length 
                         formulations are very similar to the observed data near the 
                         surface, indicating that in this region the surface plays a 
                         crucial role. At upper levels the most turbulent formulations lead 
                         to better results. This is a consequence of atmospheric decoupling 
                         when the turbulence is completely suppressed, which leads to 
                         colder results near the surface and warmer results aloft. The 
                         radiative scheme reproduces quite well the temperature decay above 
                         the boundary layer for all cases, in spite of its simplicity. On 
                         the other hand, the comparison between modeled and observed 
                         humidity profiles shows that it is necessary to improve the model 
                         by including a more complete scheme for humidity and by adding a 
                         advection scheme to it.",
