 Background observation
 9999-12-31 00:00:00 - 9999-12-31 23:59:59: Aero Laser : AL5001(VURF)
 30 seconds
 Calibration gas: Working standard traceable to certified NOAA/CMDL primary standard tanks. Zero/Span check all 6 hours. The zero air for the calibration is made by a Sofnocat CO scrubber.
Current Scale: NOAA/CMDL
 [Hourly] 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 and correlation with other trace substances and meteorological data and also with information from the station logbook and then are rejected. 30min 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 caluculated 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
