1 September 1994 – 20 February 2020: Every 202 minutes a full four-point calibration is carried out using standards produced and certified by NOAA CMDL. The response function is calculated as a quadratic function. Every 32 minutes a target gas is measured. Between two 4-point calibrations, the response function is shifted following the drift of the target gas signal. From 21 February 2020: With the introduction of a high stability new analyzer the frequency of the 4-point calibration is reduced to one per month, and no target measurement is performed. The negligible drift of the response function is followed by linear interpolation between the calibrations. |
|||||||
| The basic measurement period is two minutes, consisting of one-minute flushing and one-minute signal integration. Each one-minute average is based on 6-7 measurements. The multiport selector valve steps through the four monitoring elevation levels in eight minutes. Typically 7 data are recorded at each measurement elevation every hour. | |||||||

[Hourly] Hourly data are taken from the arithmetic mean of observed data for one hour after the technically bad data are rejected. [Daily] Daily data are calculated as the arithmetic mean of hourly data measured between 12 h and 16 h local standard time (early afternoon values having expanded spatial representativeness). [Monthly] Monthly data are calculated as the arithmetic mean of the daily (early afternoon) data if at least 10 daily data are available. |

HMS was the operator of the station and performed the measurements between 1994 and 31 Aug 2020. Since 1 Sept 2020 ATOMKI is the operator of the station and it performs the reported measurements. Since 1 September ATOMKI handles the whole historic data series. The meteorological data observed by HMS from 1994 to 2018 are available in Yearly fixed datasets until 2021. https://gaw.kishou.go.jp/search/gas_species/co2/2021 |
