| The quadratic fitting curve is determined every 8 hours by a set of 3 station working standard gases of CCl4, CH3CCl3-in-nitrogen 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 one hour raw data. CCl4 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. | |
|
[Hourly] Hourly raw data are based from observed data for one hour after the irregular and evident error data are rejected. [Daily] Daily data are taken from the arithmetic mean of selected hourly data. For the details of background daily data, please refer to https://www.data.jma.go.jp/gmd/env/ghg_obs/JMA_flag.html [Monthly] Monthly mean concentrations are calculated from background daily data. For the details of background daily data, please refer to https://www.data.jma.go.jp/gmd/env/ghg_obs/JMA_flag.html |
