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. | |

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). |
