CH-DAV: 2001
CO2 flux data between 27 Feb 2001 and incl. 23 Mar 2001 looks unusual, with consistent CO2 uptake during the night. It is possible that these fluxes are true, but an issue with the CO2 chemicals can currently not be excluded. Needs detailed check.

- Notes:
- *** Update 24 Sep 2020, 30 Jun 2021: Level-2 data was re-uploaded for FLUXNET data sharing, but with CO2 flux data between 27 Feb 2001 and incl. 23 Mar 2001 excluded from the dataset. During this time period, the CO2 fluxes look suspicious and show consistent uptake during nighttime (see Fig. 1). However, a check of the found lag times during the same period indicated that something is off during this period. H2O and H fluxes look OK. It is possible that there was an issue with the CO2 chemicals in the IRGA62. This will be investigated during the next flux calculations for this year. -LH
