Since the Covid19-lockdown in Greece (23 March 2020) counts now already more than 3 weeks, the continuous monitoring of air pollution in Athens has shown a decrease of 30-40% in the concentration of pollutants related to vehicular traffic in comparison with the period 1-22 March 2020, and at least 10-25% compared to the corresponding period in 2019 (see full Press Release here).
Measurements and analysis of the data continue systematically with the aim of monitoring the effects of the measures on the quality of the atmosphere. Data produced can be used in the long run for “smart city” decision making, towards improving their AQ through sustainable development solutions.
