Flux densities of carbon dioxide were measured over an arid, vegetation-free surface by eddy covariance techniques and by a heat budget-profile method, in which CO\* concentration gradients were specified in terms ofmixing ratios. This method showed negligible fluxes ofCO,, consistent with the baren
Methods of calibrating infrared CO2 analysers for sensitivity to CO2 and water vapour are described. Equations to correct eddy covariance CO2 flux measurements are presented for: (i) analyser cross-sensitivity to water vapour and the effects of density fluctuations arising from atmospheric fluxes of
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 d
