Analysis of the NO2 tropospheric product from S5P TROPOMI for monitoring pollution at city scale
City and Environment Interactions(2020)
Abstract
Nitrogen dioxide (NO2) is a good indicator for air quality (AQ) in urban and industrialized areas. The instrument TROPOMI on the ESA S5P satellite provides high quality daily measures of the NO2 tropospheric column from space. The lockdowns that countries and cities have implemented to mitigate the spread of Covid-19 represent an unprecedented reduction of human activities that significantly impacted AQ and NO2 emissions in urban areas.
