                         atmospheric boundary layer budgeting techniques above tropical 
                         forest near Manaus, Brazil. Comparisons were made with 
                         simultaneous measurements from two eddy covariance towers below. 
                         Although there was good agreement for daytime measurements, large 
                         differences emerged for integrating periods dominated by the 
                         night-time fluxes. These results suggest that a systematic 
                         underestimation of night time respiratory effluxes may be 
                         responsible for the high Amazonian carbon sink suggested by 
                         several previous eddy covariance studies. Large CO2 fluxes from 
                         riverine sources or high respiratory losses from recently 
                         disturbed forests do not need to be invoked in order to balance 
                         the carbon budget of the Amazon. Our results do not, however, 
                         discount some contribution of these processes to the overall 
                         Amazon carbon budget.",
