Notes

  • (bc5) … 5% Burba correction. Quality-controlled Level-2 fluxes were corrected for self-heating of the gas analyzer (Burba correction, off-season uptake correction). The correction was not fully (100%) applied, but only with a strength of 5%, which is considered more accurate for our sites due to the tilted installation angle of the open-path IRGA75.
  • Old version number: v2016-06
  • Meteo data revised by WE.

  • 5% Burba correction was applied to final, quality-controlled Level-2 IRGA75 CO2-fluxes, using the R script by WE: 02-Burba-Fluxes-Davos.R.
  • LH 28 Jul 2016:
    2005 is a special year because of the switch from the old to the new eddy covariance setup without data overlaps.

    • The first part of 2005_1 was measured with R2 and IRGA62.
    • The second part of 2005_2 was measured with R2 and IRGA75.
    • There are no data overlaps, so for this year the fluxes of both parts are combined into one file.
    • QC was done for each part separately because there were differences regarding the QC, e.g. IRGA62 does not output AGC (window dirtiness).
    • The separate QC parts were then merged into one file.
    • LH 30 Apr 2019: Burba correction was applied to the IRGA75 fluxes only.
