【 摘 要 】

Agriculture is the main source of atmospheric ammonia (NH₃). Methodologies are needed to quantify national NH₃ emissions. For European continental scale the EMEP emissions inventory with a 50 × 50 km² resolution is yearly available. However, current air quality models are often applied with higher spatial resolution, in order to obtain representative results, especially at urban and regional scales; therefore, a simple top-down approach based in the spatial interpolation of EMEP emissions is not sufficient.

The aim of this work is the development and application of a mixed top-down and bottom-up methodology for high resolution emissions inventory for the agriculture sector, based on EMEP and other public data sources (E-PRTR inventory, statistical data, etc.) for Western Spain and Portugal.

This new emission inventory was compared with EMEP and assessed using the WRF-CAMx air quality modelling system. Results highlighted the influence of the meteorology (high temperatures) and the magnitude of emissions on NH₃ air quality concentrations. The higher resolution emissions lead to the highest maximum NH₃ ground level concentrations, in specific locations.
