             abstract = "Shallow clouds are prone to appear over deforested surfaces 
                         whereas deep clouds, much less frequent than shallow clouds, favor 
                         forested surfaces. Simultaneous atmospheric soundings at forest 
                         and pasture sites during the Rondonian Boundary Layer Experiment 
                         (RBLE-3) elucidate the physical mechanisms responsible for the 
                         observed correlation between clouds and land cover. We demonstrate 
                         that the atmospheric boundary layer over the forested areas is 
                         more unstable and characterized by larger values of the convective 
                         available potential energy ( CAPE) due to greater humidity than 
                         that which is found over the deforested area. The shallow 
                         convection over the deforested areas is relatively more active 
                         than the deep convection over the forested areas. This greater 
                         activity results from a stronger lifting mechanism caused by 
                         mesoscale circulations driven by deforestation-induced 
                         heterogeneities in land cover.",
