From: Co-distribution of Light At Night (LAN) and COVID-19 incidence in the United States
Co-distribution of light at night (LAN) and COVID-19 incidence in the US states of Connecticut, New York, Texas, and California. We used ArcGIS to generate the Kernel density maps of LAN intensity and COVID-19 case rate for these 4 states. There are significant positive correlations between LAN intensity and COVID-19 case rate in Connecticut and New York; no consistent correlation between LAN intensity and COVID-19 case rate in Texas and California. Data of LAN intensity were extracted from NASA Earth Observatory and COVID-19 case rates were obtained from local health departments
