Lockdowns Save People from Air Pollution: Evidence from Daily Global Tropospheric NO<sub>2</sub> Satellite Data

Motivated by the global fear of the Coronavirus-19 (COVID-19) pandemic, we investigated whether lockdowns save people from air pollution, notably from Nitrogen Dioxide (NO<sub>2</sub>). Using daily satellite data from the National Aeronautics and Space Administration (NASA), we first fou...
