 WMO CO2 mole fraction scale.
Seven calibration cylinders from NOAA is used to provide CO2 value for working reference cylinder and define coefficients of non-linear LI-COR response.
Range of calibration gases is between 340.81 and 545.89 ppm. Reference gas is sampled every hour.
 Data is generated for 3 levels and the software computes the average concentration of the 3 levels.
 [Hourly] Hourly data are averaged from all three levels.
 [Daily]
 [Monthly] The average data from 2009 to 2010 were calculated by WDCGG
 The calibration of Loflo system was done every 4-6 weeks and was flag as C.
 Invalid: C
 Temporarily suspended
 Surrounded by undisturbed lowland tropical rain forest.
There are 3 intakes at 30m, 60m and 100m above ground level. The sample air is dried with nafion drier with a mop-up dryer of magnesium perchlorate to a dew point of below -65 C. Height of sampling is controlled by a valco valve (multi-intake selector).
