In some cases, e.g. when using a new instrument that was never used before, it is not known in which team window the maximum covariance between tubulent wind and the scalar of interest (CO2, H2O, etc…) should be searched.Therefore, it is recommended to first search for lag times in a relatively large time window (“open-lag run”) and check the histogram of found lag times and whether any peak in the distribution can be seen. Then – for the final flux calculations – search the lag again in a smaller time window. The smaller time window is defined according to the ... Read More

Currently the eddy covariance flux result outputs are re-ordered in a new folder structure using Flux Levels. Today, the Flux Levels were further refined to be more in line with definitions used in FLUXNET. In addition to Level-0, Level-1 and Level-2, there is also Level-3 (refined) and Level-4 (new). FLUXNET by default uses Level-2 fluxes (sent by PIs) and then produces Level-3 and Level-4 datasets. By adapting the FLUXNET definitions for Level-3 and Level-4, we are in line with these international conventions. For more info see here: Flux Levels ... Read More
