2次生成対応大気モデルADMER-PROの開発と検証

摘要

We developed and released an atmospheric dispersion model, ADMER-PRO, which was applicable for secondary gaseous pollutants, such as ozone of high public concern, which was easy for non-modeling experts such as public administrators to use. The ADMER-PRO has the following features; 1) it can estimate the concentrations of both primary pollutants including any individual hazardous VOC components and secondary gaseous pollutants, 2) the ADMER-PRO can estimate easily the concentrations of multiple chemical species because it contains the necessary data,such as an emission inventory for some chemical species, 3) it can estimate long-term (e.g., annual) mean concentrations often necessary for chemical risk assessments, and 4) it can work on Windows PCs with simple operations. We used the ADMER-PRO to estimate the annual mean concentrations of multiple chemical species over the Kanto and Kinki areas, and tested the predictive performance of the model by comparing the calculated results with observations. The results showed that the ADMER-PRO can approximately reproduce observations of both primary pollutants, such as NOx and individual hazardous VOC components, and secondary gaseous pollutants within a factor of two and the model has a comparatively good predictive performance. With the release of the ADMER-PRO, the chemical risk assessment and management considering both primary and secondary gaseous pollutants will be significantly enhanced.
