9. 9 Concluding remarks Analysis of EU policy with air quality scenarios 1970/2010: Crippa et al., ACPD 2015 EDGARv4.3 Consistent bottom-up global database Advantages: -international energy and agriculture statistics over time (1970-2010) -GHGs, gas and aerosol pollutants -EF following EMEP/Corinair guidelines -adequate proxies to grid emissions Disadvantages: - Less accuracy on local information (e.g. point sources for some countries) Input for GLOBAL MODELS (also using GHGs) HTAP_v2.2 Harmonised global MOSAIC of official estimates of air pollutant gridmaps Advantages: - detailed local emission estimates (national inventories) - higher spatial accuracy: correct location of point sources and use of regional proxy data Disadvantages: lower consistency -no harmonised proxy datasets -use of different EF, AD, region specific proxies -no conclusions on drivers Input for REGIONAL MODELS HTAP_v2.2 gridmaps of air pollutant emissions: Janssens-Maenhout et al., ACP 2015
