Parameter detail
Other Descriptions for Sampling and Analyses Air samples have been collected approximately weekly in glass flasks. Samples have been collected in one of two ways: 1) Filling a previously evacuated glass flask by opening a single stopcock; 2) Flushing 2 glass flasks in series with a pump and pressurizing to about 3 psig. All samples are analyzed for methane at the NOAA/CMDL laboratory in Boulder, Colorado. More detail is available in the published literature.
Scientific Aim Obtain observational constraints on the global methane budget, including global burden, long-term trend, interannual variations in trend, seasonal cycles, and spatial variations (e.g., latitude gradient). Use the observations to quantify methane sources and sinks.
