Figure 7.
Extreme monthly TCO values around the globe and their month of occurrence.
The maximum TCO value (ppbv) from any month is plotted for each 5°x5° grid cell (a) and the month in which the maximum value occurs is plotted in (b). Similarly, the minimum TCO value (ppbv) from any month is plotted for each 5°x5° grid cell (c) and the month in which the minimum value occurs is plotted in (d).
