Short summary
• Longer-term mercury measurement in the Southern Hemisphere is compared. • Mercury, in terms of monthly and annual medians and averages, is more evenly distributed than hitherto believed. • Consequently, trends observed at one or a few sites are likely to be representative of the whole hemisphere, and smaller trends can be detected in shorter time periods. • We report a change in the trend sign at Cape Point from decreasing mercury concentrations in 1996-2004 to increasing ones since 2007.
