| The quadratic fitting curve is determined every 2 hours by a set of 5 working standard gases of CO2-in-natural air mixtures in different concentrations. The mole fraction is determined by this fitting curve. | |
| The raw data from instrument is collected by the data acquisition system, and stored in the system as every 30 seconds raw data. CO2 measurements are checked every day from the headquarters through the network. All irregular measurements and information are recorded in a log book. Finally, the measurement data are checked and validated by the contributor at the headquarters. For the working standard gases and sample air, analyzer output voltages measured every second are averaged over 30 seconds. | |
|
[Hourly] Hourly data are taken from the arithmetic mean of observed data for one hour after the irregular and evident error data are rejected. For the details of background hourly data, please refer to https://www.data.jma.go.jp/gmd/env/ghg_obs/JMA_flag.html [Daily] Daily data are taken from the arithmetic mean of background hourly data. For the details of background hourly data, please refer to https://www.data.jma.go.jp/gmd/env/ghg_obs/JMA_flag.html [Monthly] Monthly data are taken from the arithmetic mean of background hourly data.
