 Calibration is carried out after each 2-hours sample measurement, using four working standard gases, which are measured for 15 minutes sequentially. The calibration data are fitted with a quadratic function. The working standard gases are calibrated against primary standard gases (NIES 95) at NIES before and after their use.
NIES 95 Scale: the primary standard gases are CO2-in-air mixtures and were prepared gravimetrically with a precise balance.
 
 [Hourly]
 [Daily] Daily mean concentrations are calculated by averaging the hourly data obtained during the reported day.
 [Monthly] Monthly mean concentrations are calculated by averaging the daily data obtained during the reported month.
 9 : The daily mean calculated with lesser than twelve hourly data or the monthly mean calculated with lesser than twenty daily data.
 Temporarily suspended
 The height of the air intake is 51 meters above ground level (96 meters above mean sea-level). Three cold traps are used to dry the air samples. The temperatures of the first, second and third traps are 2 , -45 and -65 ℃, respectively. The NDIR outputs data every second, but 5-seconds averages are recorded by the computer.
