                         Amazonian tropical forest and an embedded deforested clearing are 
                         presented. Observations comprise a continuous 60-day run of data 
                         from mid-October to mi-December 1990, covering the end of the dry 
                         season and beginning of the wet season. Mean hourly observations 
                         are calculated for the hole period; and for two 10-day periods, 
                         one in the dry season and one at the start of the wet season. Much 
                         greater variation in weather variables was observed at the 
                         clearing compared with over the forest. While the mean values of 
                         temperature and specific humidity deficit differed by less than 1 
                         C and 1 g kg-1 respectively, their daily ranges at the clearing 
                         were twice those at the forest. Mean daily albedo of the forest 
                         was 1.1 per cent, agreeing well with other tropical forest 
                         measurements, and of the clearing was 16.3 per cent, somewhat 
                         lower than the values currently being used in GCMs. The surface 
                         energy balance was investigated and mean available energy 
                         calculated for each site. The significant difference in the daily 
                         pattern of net radiation between the sites was found to be least 
                         as much due differences in the langwave radiation balance as to 
                         differences in albedo. the diurnal pattern of net radiation 
                         therefore changed between dry and wet period as the higher plant 
                         water stress experinced by clearing vegetation alterd the daily 
                         temperature cycle.",
