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

Cities in the tropics are forecast to be amongst the most populated in the world by 2100. Here we use the long record of satellite observations to assess current trends in air quality to characterise the trajectory of air quality due to unprecedented growth in the absence of environmental policies.
