We present data on sulphur (5) deposition via rime and snow collected at 10 mountaintop sites in the Czech Republic (CR) during three consecutive winters (2009-2011). The mean concentrations in rime ranged between 3.35 mg L-1 [site Tetrevec (TET) in the north] and 0.78 mg L-1 [site Kamena Loucka (LOU) in the south]. The most 5-polluted site thus had 5 concentrations in rime that were approximately four times higher than the least 5-polluted site. Across the sites, 5 concentrations in rime were 5-10 times higher than in snow. TET, identified as the most 5-polluted site, received as much as 60% 5 from rime and only 40% 5 from snow. Our results indicated a substantial decline in 5 rime deposition since the 1990s, following the introduction of desulphurisation measures in the CR. The results of direct measurements of wintertime 5 deposition via rime are discussed in the context of annual occult deposition, including both rime and fog, obtained from a data-driven geostatistical model. According to our model, occult 5 deposition ranged between 0 and 1.5 g m(-2) year(-1) over 99.7% of the forested area of the CR, and generally increased with altitude. At nine sites, the winter-time deposition of 5 via rime corresponded to 5-13% of annual wet-only 5 deposition, while it reached 25% at the most 5-polluted TET site. In environmental studies, the 5 deposition pathway via rime should not be neglected, as it might substantially contribute to the total S deposition flux even in mountains of medium elevation.
