                         that a complete deforestation of the Amazon basin would lead to a 
                         significant climate change; however, it is more difficult to 
                         determine the amount of deforestation that would lead to a 
                         detectable climate change. This paper examines whether cloudiness 
                         has already changed locally in the Brazilian arc of deforestation, 
                         one of the most deforested regions of the Amazon basin, where over 
                         15% of the primary forest has been converted to pasture and 
                         agriculture. Three pairs of deforested/forested areas have been 
                         selected at a scale compatible with that of climate model grids to 
                         compare changes in land cover with changes in cloudiness observed 
                         in satellite data over a 10-year period from 1984 to 1993. 
                         Analysis of cloud cover trends suggests that a regional climate 
                         change may already be underway in the most deforested part of the 
                         arc of deforestation. Although changes in cloud cover over 
                         deforested areas are not significant for interannual variations, 
                         they are for the seasonal and diurnal distributions. During the 
                         dry season, observations show more low-level clouds in early 
                         afternoon and less convection at night and in early morning over 
                         deforested areas. During the wet season, convective cloudiness is 
                         enhanced in the early night over deforested areas. Generally 
                         speaking, the results suggest that deforestation may lead to 
                         increased seasonality; however, some of the differences observed 
                         between deforested and forested areas may be related to their 
                         different geographical locations. (C) 2003 Elsevier Science Inc.
