“…Exposure maps in particular are useful for indication of areas with high O 3 phytotoxic potential for forests and were already used across the Czech forests earlier [ 26 ]. Spatial patterns of O 3 seasonal means are useful for estimation of O 3 deposition as published for the Czech coniferous and deciduous forests by [ 23 ] and for estimation of stomatal flux.…”

Ambient ozone (O3) is an important phytotoxic pollutant, and detailed knowledge of its spatial distribution is becoming increasingly important. The aim of the paper is to compare different spatial interpolation techniques and to recommend the best approach for producing a reliable map for O3 with respect to its phytotoxic potential. For evaluation we used real-time ambient O3 concentrations measured by UV absorbance from 24 Czech rural sites in the 2007 and 2008 vegetation seasons. We considered eleven approaches for spatial interpolation used for the development of maps for mean vegetation season O3 concentrations and the AOT40F exposure index for forests. The uncertainty of maps was assessed by cross-validation analysis. The root mean square error (RMSE) of the map was used as a criterion. Our results indicate that the optimal interpolation approach is linear regression of O3 data and altitude with subsequent interpolation of its residuals by ordinary kriging. The relative uncertainty of the map of O3 mean for the vegetation season is less than 10%, using the optimal method as for both explored years, and this is a very acceptable value. In the case of AOT40F, however, the relative uncertainty of the map is notably worse, reaching nearly 20% in both examined years.

“…Across the EU, mapping of background O 3 at a fine spatial scale (1 × 1 km) was carried out [ 20 ], as well as mapping of exposure index AOT40 at 2 × 2 km grid resolution [ 21 , 22 ]. Across the Czech Republic, the method of [ 15 ] was applied for ozone deposition mapping [ 23 ].…”
