ABSTRACT
In the original article, there was a wording error on the way that the reduction percentages of air pollutant concentrations were expressed. It is not a reduction percentage but a percentage of increase that would have been observed in the absence of lockdown. A correction has been made to Discussion, “Summary of Findings,” first paragraph: We replaced the following sentences: “The mean reduction in PM10 concentrations was 8.3%, with values ranging from−1.8 to 39.8% depending on the municipality. For NO2 concentrations, the mean reduction was 29.0%, with values ranging from 3.5 to 187.8% depending on the municipality.” by: “The daily mean difference between the estimated PM10 level during lockdown and its reference (modeled concentrations without lockdown) was −8.3 μg.m−3. This difference was −2.1 μg.m−3 for NO2.”.In the original article, there was a mistake in Table 2 as published. The four columns entitled “Reduction percentage” were not defined. The corrected Table 2 appears below. The authors apologize for these errors and state that this doesnot change the scientific conclusions of the article in any way. The original article has been updated. Copyright © 2022 Adélaïde, Medina, Wagner, de Crouy-Chanel, Real, Colette, Couvidat, Bessagnet, Alter, Durou, Host, Hulin, Corso and Pascal.
