Compare real-time worldwide air quality levels with AirVisual's interactive air quality and pollution map. Learn from PM2.5 trends and our ranking of most polluted cities in the world.
The UK’s modern approach to air quality management has been strongly influenced by the European Union’s environmental regulations. The UK’s target limits for PM2.5, the most hazardous pollutant to human health, are aligned with the EU target which is an annual mean of <25 µg/m3– wit...
map. Additionally, with the advancement of remote-sensing observation in the last decades, techniques have been developed for using these observations as constraints onpollutant sources. Likewise, during summer and premonsoon months, the transboundary movement of airborne particulates originating in Middle...
Existing methods for fine-scale air quality assessment have significant gaps in their reliability. Purely data-driven methods lack any physically-based mechanisms to simulate the interactive process of air pollution, potentially leading to physically inc
Data on the meteorological factors should ideally correspond to locations from where the pollutant data is collected at specific monitoring stations, for the matching period (27 days) in the two years. There may also be interactive or combined impacts of these factors, with corresponding implications...

Using the interactive map of air quality monitors, the PM2.5monitor closest to the participant’s birth zip code that was active using the participants birth year was located. If multiple monitors were equivalently close to the center of the zip code, a monitor either east or west was prefer...
The map shows the strong variability of the AOD, with very low values over the Tibetan Plateau (<0.1) and high values (up to 0.7 and locally even >0.9) in the eastern part of China where 94% of the population lives [86]. The strong anthropogenic pressure in the highly industrialized ...
According to the above theoretical analysis, this paper draws the path map of the influence of air pollution control auditing on carbon emissions, and proposes Hypotheses 1, 2, and 3. Hypothesis 1. Air pollution control auditing can significantly reduce carbon emissions and carbon emission intensity...
