Meanwhile, CESBIO<\/abbr> researcher Simon Gascoin built a map that compares NO2<\/sub> concentrations over the last 30 days<\/a> with the same period in 2019.<\/p>\n

Data for these analyses generally come from the Copernicus Programme\u2019s Sentinel-5P satellite. The Copernicus Atmosphere Monitoring Service issued a warning last week about using the data improperly<\/a>.<\/p>\n

Concentrations of NO2<\/sub> in the atmosphere are highly variable in space and time: they typically vary by one order of magnitude within each day and quite substantially from one day to another because of the variations in emissions (for example the impacts of commuter traffic, weekdays and weekend days) as well as changes in the weather conditions. This is why, even if observations are available on a daily (currently available from satellites) or even hourly (ground-based observations) basis, it is necessary to acquire data for a substantial period of time in order to check that a statistically robust departure from normal conditions has emerged.<\/p><\/blockquote>\n

Cloud cover is a factor that needs to be taken into account as well.<\/p>\n
