The suddenly enforced COVID-19 pandemic lock-down has impacted the Earth’s environment, and several studies have reported a significant change in air pollution using remote sensing data. In this study, we highlight significant changes in the environment due to reduced human activities using MODIS, Senti-nel-5 and NASA-USDA/SMAP satellite data. Critical parameters such as nitrogen dioxide, land surface temperature, surface soil moisture and normalized difference vegetation index were compared (pre-pandemic and post-pandemic) for six highly impacted cities around the world. This study is crucial for envi-ronmental management to maintain sustainability of the Earth’s ecosystem.
