    • Data for manuscript about IRGA comparison (Sabbatini et al.) (not uploaded to FLUXNET, see Notes)
  • Flux Calculations By: LH

Notes

  • Info about the PI dataset: CH-DAV FP2020 (1997-2019)
  • For CH-DAV, we currently share IRGA75 fluxes for 2013 via FLUXNET. Here we also calculated the concurrently measured IRGA72 fluxes.
  • These fluxes were calculated to be shared for a manuscript that is in preparation at the time of writing (Sep 2019). The ms compares IRGA72 and IRGA75 fluxes during time periods where both instruments measured at the same site.
  • Level-2 fluxes can be created on demand.

Notes

  • Info about the PI dataset: CH-DAV FP2020 (1997-2019)
  • (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.
  • Date: May / June 2016
    Flux Years: 2005-2015 / EddyPro Version Used: 6.1.0 / Tool, Python Used: FluxCalc 0.74 with Anaconda3

  • 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.
