Short Report – QA/QC Meeting Jun 2020

25 Jun, 2020 QA/QC Short Report 8

Meeting Date: 25 Jun 2020

Participants

LH, IF, RM, MG, AS, MS, TB (7)

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.

More scripts are now open source on GitLab:
- FIME File Merger: Merges data files.
- FISP File Splitter: Splits files of longer duration into files of shorter duration and more.
After calculating fluxes, be sure to check the _scf (spectral correction factor) variables in the EddyPro full_output file: if there are many (most) values larger than 2, this means that the spectral correction has probably not worked and the fluxes might be overestimated.
N2O fluxes at CH-AES look suspiciously good. Measurements with a reference gas should be done to check if flux patterns still emerge. In addition, every detail that can be checked should be checked and documented. If these fluxes are validated and later published, a lot of very detailed questions will emerge. And if the fluxes are “real”, then these results could have considerable implications for agriculture.
