Trends in air quality in the fastest growing cities in the world

Cities in the tropics are forecast to experience rapid population growth this century. We use the long record of satellite observations of multiple air pollutants to estimate recent trends in air quality, diagnose the main drivers of these trends, and estimate the impact on public health in these cities.
