The Impact of COVID-19-Related Measures on the Solar Resource in Areas with High Levels of Air Pollution
Restrictions enacted to reduce the spreading of COVID-19 have re-sulted in notably clearer skies around the world.

Restrictions enacted to reduce the spreading of COVID-19 have re-sulted in notably clearer skies around the world. In this study, weconfirm that reduced levels of air pollution correlate with unusuallyhigh levels of clear-sky insolation in Delhi, India. Restrictions herewere announced on March 19th, with the nation going into lockdownon March 24th. Comparing insolation data before and after thesedates with insolation from previous years (2017 to 2019), weobservean8.3%G1.7% higher irradiance than usual in late Marchand a 5.9%G1.6% higher one in April, while we find no significantdifferences in values from previous years in February or early March.Using results from a previous study, we calculated the expected in-crease in insolation based on measured PM2.5 concentration levels.Measurements and calculations agree within confidence intervals,suggesting that reduced pollution levels are a major cause for theobserved increase in insolation. |
