This dataset includes results obtained with the CAMx model at 5 km resolution over the Po-Valley (Italy). It consists of a series of simulations corresponding to different emission reduction scenarios for three sectors: agriculture, transport and industry. These three sectors agriculture, transport and industry are reduced independently from each other and/or in a combined way by 50 and 100%. All possible combinations of reductions are performed leading to seven different simulations Based on the same set of input data, an additional simulation has been performed with CAMx using the built-in tagging species module (PSAT). All simulations are performed with a resolution of 5 km for an entire meteorological year (2010). All pollutant species are available at daily (PM) or hourly (O3, NO2…) frequency. The dataset is provided with a graphical interface that allows visualizing the differences between tagging and brute force approaches or quantifying the non-linear interaction terms among sectors. The dataset and tool are available on request (mail to philippe.thunis@ec.europa.eu)
