Chromatograph for Atmospheric Trace Species
CH3CCl3 Mixing Ratio
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.
The global distribution of CH3CCl3 measured by the in situ halocarbons program is displayed above and is compared to monthly medians measured at Mauna Loa, Hawaii. Shown below are hemispheric and global means estimated from the in situ halocarbons program.
