New EEA AIR Indicator based on PODy – proposal of its part related to crops

Popis výsledku v původním jazyce

This report develops and proposes a new indicator based on Phytotoxic Ozone Dose (PODY) flux-based metric as a complementary information to the current EEA indicator AIR004, which is based on the O3 concentration-based metric AOT40. Similarly to the AIR004, the new PODY-based indicator should also show the O3 exposure of crops and forests separately. This report develops the first part of the new indicator, which is related to the flux-related O3 exposure of crops. The flux-related O3 exposure of forest trees is planned to be developed in 2026. Two options of the new indicator related to the crops are considered, i.e. the crop specific PODY indicator and a more generic metric based on the PODY used in the Integrated Assessment Modelling (i.e. PODYIAM), which can be applied for different crops. While the crop specific PODY metric provides more exact estimation of the O3 impacts on the corresponding crops, the PODYIAM is more suitable for estimating the O3 impacts on the wide variety of crops. For this reason, the metric POD3IAM for crops is recommended to be used in the PODY-based indicator for crops. In any case, the new AIR indicator based on PODY should complement the current AIR004 indicator, not substitute it.
