"Using the ambient ozone data recorded within a regular monitoring network in the Czech Republic, the AOT40 values both for forests and crops/semi-natural vegetation for vegetation periods of 1994\u20132001 were calculated. The critical level exceedance fields for threshold values set as 10 ppm h for forests and 3 ppm h for crops and semi-natural vegetation have been derived using the ARC/INFO system and its module GRID. The IDW method is used for interpolation. Effect of altitude change on ozone concentration has been taken into account. Maps for two extreme years 1994 and 1997 (both as to meteorology and ozone concentrations measured) are presented in this paper." . . . "V" . "3"^^ . "3"^^ .
