 During flask measurement the NDIR gas analyser is calibrated against three working standards (CO2-in-air) every 30-40 minutes. Working standard gases are calibrated yearly against the secondary standard.
 Uncertainties of the CO2 measurements are included. Key components of it are our ability to propagate the WMO XCO2 scale to working standards, the repeatability of the analyzers used for sample measurement, and the long-term reproducibility. The typical repeatability of the analyzers, based on repeated measurements of natural air from a high-pressure cylinder, is +/- 0.06 ppm for NDIR. Long-term reproducibility is estimated to be +/- 0.1 ppm based on repeated measurements of air from a high-pressure cylinder, or the long-term variability in the differences between measurements of test flasks on the flask-air analysis system and separate measurements of the test gas used to fill the test flasks. The scale propagation uncertainty is estimated to be 0.1 ppm, based on the reproducibility determined for scale propagation in MGO laboratory. The indicated uncertainty is confirmed by the results of RR#6 WMO intercomparison.

 [Monthly] Monthly data are the arithmetic mean of selected according to flag description event data.
 Flag description:
Retained:
+ . : Concentration difference in two simultaneously sampled flasks is less than established criteria (1 ppmv for CO2 and 6 ppb for CH4). The reported data are the mean of the two measured concentrations.
S . : Concentration difference in two simultaneously sampled flasks is more than established criteria. The reported data are the lower of the two measured concentrations.
M. : Only one concentration is available, second flask is off scale or broken.

Rejected:
.X : rejected as not representative of background conditions (>2 sigma from the smoothed concentration curve)
.Z : rejected manually as not representative of background condition.
.N : rejected due to error in sampling or analysis.

 Operational/Reporting
 Carbon dioxide (CO2) in ambient and standard air samples is detected using a non-dispersive infrared (NDIR) analyzer. The measurement of CO2 in air is made relative to standards whose CO2 mole fraction is determined with high precision and accuracy. Because detector response is non-linear in the range of atmospheric levels, at least 3 reference standards are used to calibrate detector response. Measurements are traceable to the WMO CO2 mole fraction scale by using standards from NOAA, AES, Stockholm University and from2010 directly WMO CCL standards.The samples are collected into two evacuated flasks simultaneously. Stainless steel flasks with electropolished inner walls of 1.5l volume are used.
Water vapor removal during NDIR analysis is made by an electric dry cooler with the temperature equal to -55°C
