hourly data

The figure above shows the hourly individual in situ measurements and the calculated monthly median. Error bars displayed on the monthly median data are a 1-σ measure of the instrument's precision and should not be confused with atmospheric variability.

monthly means figure

The global distribution of Nitrous Oxide measured by the in situ halocarbons program is displayed above and is compared to monthly medians measured at Mauna Loa, Hawaii.

global means figure

Hemispheric and global means estimated from the in situ halocarbons program.
