A new technique for estimating surface fluxes of trace gases, the mixed-layer gradient technique, is used to calculate isoprene and terpene emissions from forests. Profiles from the Amazon give a mean daytime emission of 3630±1400μg isoprene m-2h-1, where the uncertainty represents the standard deviation of the mean of eight flux estimates. Twenty profiles from Alabama give emissions of 4470±3300 μg isoprene m-2h-1, 1740±1060 μg alpha-pinene m-2 h-1, and 790±560 μg beta-pinene m-2h-1, respectively -from Authors
