Short Report – QA/QC Meeting June 2019

Meeting Date: 27 June 2019


SG, SB, PL, EPL, RM, PM, MG (7)


Talking Points


  • If you are (Tech-)SRP, please attend QA/QC meetings or tell LH if you can’t, needed for planning of the meetings.
  • SRP & Tech-SRP: please prepare short statement about your site and send to to LH (max. 2 sentences)
  • The purpose of QA/QC meetings is to check on current, incoming data. SRPs choose specific issues we should look at together and discuss in the group. Fluxes are checked if the respective SRP wishes to do so.


Site Reports


SRP (SG): Logger had been off so there is actually no precipitation data measured directly at the site from October 2018.
T-SRP: –


  • SG has trouble calculating fluxes on the RDS as well.


SRP (IF): QCL still has problems, now probably because of too high temperatures in the box. Therefore there are intermittent data gaps in the last month.
T-SRP: –


  • Sonic interruption due to mice biting the cables and laser had several issues. Both running now. TB has now put the cables above the ground through a duct to keep them safe from the mice. Apart from the gaps, fluxes are OK.


SRP (MG, LH): Fluxes look good and are complete.
T-SRP: –


  • Fluxes look OK. Only a small gap in May. The scrip of WE that restarts the acquisition seems to work smoothly.
  • QCL is now running and chambers are measuring respiration. We could share the QCL also for the EC system if we want. TBD.
  • MG cannot calculate fluxes on the RDS either, only directly from EddyPro from the ICOS files.


SRP (LH): No major problems, fluxes are
T-SRP: –


SRP (RM): In general, everything looks good.
T-SRP: –


  • Instruments running and fluxes look OK.
  • N2O fluxes have a large peak (24th may) over a few days that seems to be a fertilization effect, but RM is not sure because they usually do not fertilize peas. RM will check.
  • RM cannot calculate fluxes on the RDS. She will send a screenshot of the error to LH.
  • CH4 fluxes are much higher in CH-INO than in CH-CHA (at least a factor of 2, mean in CH-CHA 0.004 and in CH-INO 0.009).


SRP (EPL): Above- and below-canopy EC running smoothly and fluxes look good.
T-SRP: –



SRP (RM): Fluxes are complete.
T-SRP: –
