16 Oct, 2019 QA/QC Short Report 3

Meeting Date: 17 Oct 2019

Participants

LH, MG, RM, IF, WE (5)

Info

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.

Talking Points

Please move flux results from the group drive to the grasslandserver GL-PROCESSING regularly.
SFN HP is regularly updated and now includes e.g. lots more of Site Info that can be shared easily with outside data users. For example, check out the Site Info for CH-OE2.
Amp 0.6.0 is now available on the RDS. The app is now stand-alone, i.e. no need to install Python and stuff.
For the next meeting, please calculate recent fluxes (or the whole year if not yet available) and move the results to the folder P:\Flux\QAQC_meetings_data. With Amp now working, we can easily merge recent flux results with previous results, i.e. there is no need to calculate the full year Level-0 fluxes in one run.

Site Reports

CH-AWS

SRP (LH for SG): In October, there is still high CO2 uptake during the day. And, due to the high uptake rates in June, we might soon need to reconsider out +/- 50 umol m-2 s-1 threshold during quality control.
T-SRP: –

CH-CHA

SRP (IF): Cut on 17.09. reduced CO2 uptake. The QCL went on retreat with us, data gap at beginning of September. Not sure what happened on the 23.09., fertilization? Strange peak in N2O.
