 Background observation
 9999-12-31 00:00:00 - 9999-12-31 23:59:59: Hewlett Packard Modified HP 6890 GC 020394(Gas chromatography (ECD))
 5 minutes
 Calibration gas: SF6 in natural air. Calibrations are carried out every 15 minutes using secondary standard tanks, which have been calibrated to primary standards of NOAA/CMDL.
Current Scale: NOAA/CMDL Scale
 [Hourly] The data acquisition system provides two ambient air values, and one calibration value every 15 minutes. Invalid data caused by local impact, malfunction or other effects are detected by comparison and correlation with other trace substances and meteorological data and also 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 with more than 2/3 of all data. For reporting to WDCGG hourly mean values are calculated from these half hourly data.
 [Daily] Take the arithmetic mean of selected half hourly data with the number of data more than 31.
 [Monthly] Take the arithmetic mean of selected half hourly data with the number of data more than 960.
1: valid value
6: missing value due to calibration
9: missing

0 = valid value,
3 = invalid data,
6 = calibration
 Temporarily suspended
 GC equipped with a packed column and a electron capture detector (EDC).
Modified GC system with ChemStation Software for quasi-continuously, automatically application.
