Web6 dec. 2024 · Is methane measurement adequate? At present, global monitoring is limited to the NOAA network and a small number of rigorously intercompared allied measurement programs. There are few long-term time series for mole fraction and even fewer high precision multi-sample monitoring stations for δ13 C CH4. Web5 apr. 2024 · The Global Monitoring Division of NOAA’s Earth System Research Laboratory has measured methane since 1983 at a globally distributed network of air sampling sites ( Dlugokencky et al., 1994 ). A global average is constructed by first smoothing the data for each site as a function of time, and then smoothed values for each site are plotted as a ...
