Description: Downloads and examines air quality data from three
        sources. The Central Pollution Control Board (CPCB) of India
        operates more than 600 monitoring stations. Open Air Quality
        (OAQ) <https://oaq.notf.in> collects data from low-cost sensor
        networks in India. The Atmospheric Composition Analysis Group
        at Washington University in St. Louis gives satellite estimates
        of fine particulate matter (PM2.5) for all areas of the Earth
        <https://www.satpm.org>. The package calculates the CPCB
        National Air Quality Index and the mean PM2.5 in an area.
