All data are based on NOAA/CMDL scale. Calibration gas: SF6 in natural air. Calibrations are carried out every 15 minutes using working standard tanks, which have been calibrated to a group of 6 NOAA station standards which envelope the atmospheric concentrations of SF6 |

Processing of GC Data With a software, called GC-Organizer, written by the team of I.Levin at University of Heidelberg the measured 5 min raw data are visually controlled in respect to outliers and the standard deviation during measurement of the standards. Outliers are removed with this graphical tool. After this pre-check 30 min atmospheric concentrations and standard deviation of CO2, CH4, SF6 and N2O are calculated with the same software program. Afterwards these 30 min data are imported with a self written software program, called Dafit (Description see: www.gawstat.de). The 30 min data are screened graphically. For a second validation, episodes of local pollution, also power failures, Instrument repairs etc. can be flagged. The digital log-book and if required, trajectories and co correlation with simultaneously measured data are used in to verify the CO2, CH4, N2O and SF6 data. Then from the flagged data for scientific purpose and export aggregation to 60min, 1day, 1month and 1year data is calculated in a standardized way for each, simultaneously also files with the WDCGG export format are produced in a standardized way to automate the workflow. |

[Hourly] Mean Processing for the GC-data CO2, CH4, N2O and SF6 The data acquisition system provides one value every five minutes raw data. Zero/calibration factors and data protocols are used to convert raw data into calibrated data. Invalid data caused by local impact, malfunction or other effects are detected by comparison/ correlation with other trace substances and meteorological data and with information from the station logbook and then are rejected. 30 min mean values are generated by calculating the arithmetic mean of the remaining data. For reporting to WDCGG hourly mean values are calculated from these half hourly data. Until 2018: nvalue refers to the number of available 30min averages within the respective hour. From 2019: nvalue refers to the number of single measurements within the respective hour. [Daily] Mean Processing for the GC-data CO2, CH4, N2O and SF6 Daily mean values are generated by calculating the arithmetic mean of the available hourly data within the respective day. nvalue refers to the number of available hourly averages within the respective day. [Monthly] Mean Processing for the GC-data CO2, CH4, N2O and SF6 Monthly mean values are generated by calculating the arithmetic mean of the available daily data within the respective month. nvalue refers to the number of available daily averages within the respective month. |
