Özet

In this study, NH3 and NMVOC emissions from agricultural activities were updated and compared with EMEP inventory for a region known for agricultural activities in Turkey. An advanced air quality model, CMAQ, was used to determine the spatio-temporal distribution of NH3 and NMVOC, which have seasonal patterns. Model was performed for base (EMEP 2018 emissions) and scenario (updated 2019 emissions) cases and 2018 summer months with high-resolution grid size. Moreover, secondary particle formation over the domain was identified. This study is significant due to the agriculture emissions to be updated and re-gridded using high-resolution CORINE land use data and examined of pollutants which are climate dependent. EMEP agriculture emissions were 955.92 kt/annual and 486.60 kt/annual (Turkey totals), and 284.35 kt/annual and 227.54 kt/annual (Turkey emissions in the domain) for NH3 and NMVOCs, respectively; updated agriculture emissions were found as 579.58 kt/annual and 289.97 kt/annual (Turkey totals), and 195.01 kt/annual and 98.66 kt/annual (Turkey emissions in the domain) for NH3 and NMVOC. Not only the emissions were different in overall quantities, but also there were spatial differences in concentrations between cases. For NH3, the largest source of which is agriculture, monthly averaged concentration differences were found up to 60% in some areas of the domain due to the distribution of total emissions over agricultural areas unlike the EMEP spatial distribution methodology. VOC emissions were overestimated in EMEP inventory; thus, a difference had also become in concentrations between two cases. Highest concentrations were found in July for PM2.5, PM2.5(OC), PM2.5(SO4), and PM2.5(NH4).
