the air quality is poor in Lyon this Monday, March 28
A sunny start to the week, but particularly poor air quality this Monday, March 28 in Lyon. The reason: a high level of fine particles from the northwest.
After a sunny weekend, the air quality is described as poor by the Atmo laboratory, air quality specialist in Auvergne-Rhône-Alpes. “With the resumption of activities, the situation will be fragile in the Lyon conurbation. The air quality should again be poor in connection with the concentrations of fine particles, even if the southerly wind could prevent too high a rise”he indicates.
And it is ozone that could be responsible for this strong deterioration, despite the arrival of a light wind from the south.
The return of the Sahara to Lyon?
In the rest of the week, the laboratory indicates a possible return of sand from the Sahara between Rhône and Saône. “Tuesday March 29, upstream of a rainy disturbance, a strong southerly wind should be accompanied by a rise in Saharan particles“.
No certainty for the moment assures the regional specialist. “The situation is […] quite uncertain at this time, and a real improvement does not seem possible until Wednesday. Air quality remained degraded to poor“Alert Atmo Auvergne-Rhône-Alpes. To be continued, but this may not be the time to wash your car.
