Air quality remains poor this Saturday in Lyon

After strong winds during the day on Friday, which allowed air quality to improve somewhat, it remains degraded for Saturday, May 17 in Lyon. The Atmo website states that "the still strong north wind should once again contain the formation of ozone and the expected ATMO index therefore remains degraded."

Multi-pollutant pollution therefore remains quite present in the atmosphere, while ozone pollution will be more significant during the day and particularly between 1 p.m. and 4 p.m.
