| The linear regression line is determined every 8 hours by a gravimetric standard gas of HFCs-in-natural air mixtures. The mole fraction is determined by this regression line. | |
| The raw data from instrument is collected by the data acquisition system,and stored in the system as every one hour raw data. HFCs measurements are checked at the site by an operator every day. All irregular measurements and information are recorded in a log book. Measurement data are transmitted to the headquarters every month and are checked again there. 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.
