Short Report – QA/QC Meeting Oct 2020

Meeting Date: 29 Oct 2020


LH, AS, RM, MG, TB (5)


Talking Points

  • CH-DAV PI fluxes (up to Level-4) are now available in FP2020 (1997-2019)
  • Checked fluxes CO2, H2O, CH4 and N2O.
  • Processing for CH-LAS will restart soon.



  • 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

CO2 flux



CO2 flux, no QC




LH (SRP): Good year with few gaps, fluxes look good.

CO2 flux, here NEE (co2_flux + co2_strg) after some QC and despiking (and also some weak ustar filtering with constant threshold 0.05)




RM (SRP): Harvest on 15 September and slurry application on 20 October.

CO2 flux, QC only absolute limits (CO2 80/-80)






RM (SRP): Temporary grassland (clover-grass mixture) growing since 19.08.2020. Sonic died again due to defective transducers (the only pair which was not replaced so far). New Sonic installed on 15 October. First cut of temporal grassland on 19 October.
