Recent advances in satellite mapping of global air quality: evidences during COVID-19 pandemic.

ABSTRACT: There was a significant decline in air pollution in different parts of the world due to enforcement of lockdown by many countries to check the spread of the coronavirus (COVID-19) pandemic. In particular, commercial and industrial activities had been limited globally with restricted air and surface traffic movements in response to social distancing and isolation. Both satellite remote sensing and ground-based monitoring were used to measure the change in the air quality. There was momentous decline in the averaged concentrations of nitrogen dioxide (NO₂), carbon dioxide (CO₂), sulphur dioxide (SO₂), methane (CH₄) and aerosols. Many cities across India, China and several major cities in Europe observed strong reductions in nitrogen dioxide levels
