CH-LAE: 2017

23 May, 2019 Flux Notes

FF-202101

Current

  • Setup: Setup since 2004
  • Time Period(s): 2017_1, 2017_2
  • Instruments: HS50, IRGA75, IRGA72
  • Final Flux Version: HS50-IRGA72-IRGA75_FF-202101
  • Scripts: EddyPro 7.0.6, BICO v0.5.1, FLUXRUN v0.5.0, DIIVE v0.19.0-alpha, ReddyProc 1.2
  • Flux Levels:
  • FLUXNET Upload: 09 Jun 2021 (merged Level-1 IRGA72 and Level-1.1 IRGA75 fluxes for full FLUXNET Warm Winter 2020 dataset)
  • Flux Calculations By: LH
  • Meteo Screening By: EPL

Notes

  • IRGA72 fluxes are prioritized. Gaps (only few) in IRGA72 fluxes were gap-filled with IRGA75 fluxes (corrected for self-heating), if IRGA75 fluxes were available in these gaps.
  • Separate Level-1 fluxes for IRGA72 and IRGA75 are available in HS50-IRGA72-IRGA75_FF-202101. For IRGA75, Level-1.1 fluxes are also available.
  • The short time period at the end of the year that is affected by the Wrong Calibration Gas has been corrected.
  • Fluxes have been updated during the creation of the PI dataset CH-LAE FP2021 (2004-2020).
  • Fluxes from the open-path LI-7500 (IRGA75) have been corrected for self-heating.
  • Info about the PI dataset: CH-LAE FP2021 (2004-2020)
  • Info about the different flux levels: Flux Processing Chain

  • FLUXNET Upload: 23 May 2019 (Level-1 for FLUXNET European Drought Study 2018 dataset)
  • Flux Calculations By: EPL
  • Meteo Screening By: EPL

Notes

  • Fluxes have since been updated.
  • Known issues: Fluxes have not been corrected for the Wrong Calibration Gas 2017 issue (unknown at the time). See here for affected time periods: Setup since 2004. However, this issue only affects the last approx. 2 weeks of December, a correction might therefore not be worthwhile since this has virtually zero impact on CO2 budgets etc.
  • Unfortunately I did not have all details available, but from the file in the database upload I concluded the the IRGA72 fluxes were uploaded. -LH
  • Some files are missing in the output folder (the converted raw data csv files and raw data csv plots).
  • The Level-2 fluxes are missing, but data were uploaded.
  • There was no log file available, therefore the used versions of FCT and EddyPro are unknown (probably FCT 0.74, EP 6.1.0).
