 The air samples are taken by using Suma Steel passivated canisters, evacuated in the laboratory by means of a vacuum pump, then pressurized at the sampling site to 38-40 PSIG.
Twice a week /Mondays and Thursdays at 12 GMT, 10 minutes /Gas chromatograph with capillary column on the Chrompack CP 9000 with FID.
Scientific Aim : Obtain observational constraints on the global methane budget, including global burden, long-term trends, interannual variations in trend, seasonal cycles and spatial variations (e.g., latitude gradient). Use the observations to quantify sources and sinks.
