Description
| - The ADVEX project involved extensive advection measurements at three sites differing in topography. One aim of the project was to measure the CO2 balance in night-time conditions, in an attempt to improve NEE estimates. Horizontal advection varied greatly from site to site and from one wind sector to another, with the highest values reached at large friction velocities. The night-time NEE estimates deduced from the mass balance were incompatible with biologically driven fluxes because they varied strongly from one wind sector to another, their order of magnitude was not realistic and they still showed a trend vs. friction velocity. From a critical analysis of the measurement and data treatment we concluded that the causes of the problem are related to the measurement representativeness or the simplified CO2 mass balance equation used. This suggests that the improvement of eddy flux measurements by developing an advection-completed CO2 mass balance at night would be practically difficult.
