✦ Synopsis

The axis labels in Figure on p. 71 were interchanged, i.e., the y-axis should be H and the x-axis should be hE. As a result, the sentence beginning on line 6, p. 72 should read: Flux corrections increase with hE at any value of H for an analyser insensitive to water vapour (Figure ), whereas they decrease with H when p/a = 3 x 10-3 (Figure ).

Eddy fluxes of CO2 estimated using a sonic anemometer and a closed-path analyser were, on average, 16% lower than those obtained with the same anemometer and an adjacent open-path CO1 analyser. Covariances between vertical windspeed and CO2 density from the closed-path analyser were calculated using
