 Calibration gas: CO2 in natural air
Current Scale: NOAA/CMDL Scale
 All values are quality controlled
 [Hourly] Only technically biased values are removed (caused by calibration or malfunctioning of equipment).
 [Daily] Take the arithmetic mean of selected halfhourly data if at least 2/3 of the halfhourly values of one day are available.
 [Monthly] Take the arithmetic mean of selected daily data if at least 2/3 of the daily values of one month are available.
 Flags put on hourly data are as follows.
...- 2005: 1 = valid value, 6 = calibration, 9 = error code
2006 -...: 0 = valid value, 3 = invalid data, 6 = calibration
 Temporarily suspended
 Air inlet
A device placed within a small refrigerator (gas cooler) at 4°C humifies the sample or the calibration gases in bubbler. Then gas runs through two cooling traps to remove the water vapour.
