Assessment of Ambient Multipollutant Exposure and Health Impacts Over India Using the Novel Satellite-Based Multi-Pollutant Index.

ABSTRACT: Ambient air pollutants are reported to have adverse health impacts, which could be better assessed by examining human exposure to multiple criteria pollutants or through a multi-pollutant Air Quality Index (AQI). As compared to AQIs developed using in situ measurements of pollutants across sparse monitoring stations, satellite-based products such as ambient PM_2.5 or NO₂ provide better spatiotemporal patterns. Here, we examine the long-term (2005-2019) air pollution exposure and health impacts over India with the novel Satellite-Based Multi-Pollutant Index (SMPI). The high spatial resolution (1 km × 1 km) SMPI over India reveals pollution exposure hotspots in most states and districts over the Indo-Gangetic Plain (IGP) and eastern states. The spatiotemporal patterns in
