Figure Annual changes in concentrations of PM10, O3 and NO2 in the period 2001–2010
The data presented were derived from a consistent set of stations in all years. Statistically significant trends (level of significance 0.1) are calculated by applying the Mann-Kendall test. Increasing concentrations are indicated with red dots and decreasing concentrations with green dots, when statistically significant. The applied method is described in de Leeuw, 2012.

Figure Annual changes in concentrations of PM10, O3 and NO2 in the period 2001–2010
Statistically significant trends (level of significance 0.1) are calculated by applying the Mann-Kendall test. The trend slopes are indicated with coloured dots when statistically significant. Red dots indicate increasing concentrations. The applied method is described in de Leeuw, 2012

Figure Annual variation in the ozone AOT40 value (May-July), 1996-2006
A number of stations were excluded from the analyses because data coverage was too low and/or the stations were not operational during at least 8 years in the period 1996-2006.

Figure Annual variation in the ozone AOT40 value (May-July) in (μg/m³).h, 1996-2007
Average values over all rural stations which reported data over at least nine years in the period 1996-2007. The light blue line corresponds to the 5-year averaged value.
