Summary: | Globally-averaged, monthly mean atmospheric nitrous oxide (N2O) concentrations determined from a globally distributed network of air sampling sites from 2001-Present. | |
Method: | The Global Monitoring Division of NOAA’s Earth System Research Laboratory has measured nitrous oxide since 1997 at a globally distributed network of air sampling sites. 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 fitted as a function of latitude at 48 equally-spaced time steps per year. Global means are calculated from the latitude fits at each time step. The 95% confidence interval is the uncertainty presented in the time series. | |
