Abstract in another language

For establishing correct mass or energy balances at the Earth's surface, detailed and correctmeasurements of air constituent fluxes are needed. Flux measurements obtained from the eddycovariance technique have to pass several corrections of different relevance in order to give correct fluxdata. One of these corrections, the `Webb correction', is analysed herein from latent heat flux and CO2flux data recorded during two field experiments. The significance of this correction for the latent heat fluxdata varies with the air humidity and the Bowen ratio. The correction changes the latent heat flux valuesonly a little, but significantly (by 2 to 3%). For other air constituents (like CO2), the Webb correction ismuch more important (20 to 30% of the flux).
