Figure Lengend Snippet: Data coverage. Fraction of valid hourly measurements per month (in %) for ( a ) GEM and ( b ) RM active/continuous monitoring. That fraction is capped at 75% and 25% for GEM and RM, respectively, from Jan 2012 to Nov 2015 due to the operating principle of the Tekran® speciation unit. The yellow rectangles indicate when a new Tekran® 2537 A/B model Hg analyser was installed due to instrument failure. Panels ( c – e ) show current data availability for GEM passive/discrete, RM active/discrete, and wet deposition monitoring.

Figure Lengend Snippet: Reactive Mercury (RM) concentrations inferred from the Tekran® speciation unit (from 2012 to 2015; RM = RGM + PBM2.5) and from the use of polyether sulfone cation-exchange membranes (PES-CEMs; from Dec 2015 to Feb 2022). n indicates the number of data points/samples. Note that RM measurements are still ongoing using PES-CEMs but samples collected after Feb 2022 have not been analysed yet (see Fig. ). The violin plots show the kernel probability density and include a marker for the median (in red) and a box indicating the interquartile range (IQR). As in standard boxplots, the upper (lower) whisker extends from the box to the largest (smallest) value no further than 1.5 × IQR. Values below the detection limit were discarded.
