The Dimming of Lights in India during the COVID-19 Pandemic

Payne Institute Earth Observation Group researchers Tilottama Ghosh, Christopher Elvidge, Feng-Chi Hsu, Mikhail Zhizhin, and Morgan Bazilian wrote how the monthly Suomi National Polar-orbiting (NPP) Visible Infrared Imaging Radiometer Suite (VIIRS) Day–Night Band (DNB) composite reveals the dimming of lights as an effect of the lockdown enforced by the government of India in response to the COVID-19 pandemic. The changes in lighting are examined by creating difference maps of a pre-pandemic pair and comparing it with two pandemic pairs.  October 10, 2020.
