Maritime sector contributions on NO2 surface concentrations in major ports of the Mediterranean Basin
article
The aim of this study is to estimate the contribution of the maritime sector on the air quality of major Medi terranean ports with the Long Term Ozone Simulation-European Operational Smog (LOTOS-EUROS) chemical transport model, using two source apportionment methods: the brute-force emission scenario methodology and the labelling approach. With the brute-force method NO2 shipping concentrations are estimated by the ratio of the difference between two model runs - with original and reduced emissions - and the equivalent emission reduction factor. In the labelling, emitted species are explicitly labelled per sector and tracked through all model processes. Simulations are performed for a one-year period, from May 2018 to May 2019 and the two methodologies are intercompared. The methods show strong agreement between NO2 shipping contributions (R > 0.95) and dif ferences of ~14%. A sensitivity analysis carried out using the brute-force method indicates that a linear regime between NOX emissions and NO2 concentrations holds, when adopting a low to moderate emission reduction
