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 third choice is possibly the most theatrical because it can change the entire colour of the map to reflect the current state of the air. Currently, it is a brownish/yellow which indicates “Moderate” air quality. If the viewer finds the colour to be overpowering then by de-selecting ...

The Purple Air air-quality map on Friday Sept. 11, 2020, shows most of the west coast with hazardous levels of pollution from wildfire smoke. Screenshot As record-breaking fires wreak havoc on the Western United States, they're also releasing massive amounts of smoke and ash into the atmos...
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
On the other hand, the average altitudes reached by the thermal inversion in summer and winter are approximately 500 and 1500 m above sea level, respectively27,28. Figure 2 Map with the study area and the locations of the Lima air quality monitoring stations: ATE, Campo de Marte (CDM), ...
The time series of SO2, NO2 and AOD show the initial increase of the concentrations early in the 21st century, as well as the progressive effects of the measures by the Chinese government to improve the air quality over China. In addition, the AOD data can be used to obtain information ...
The observations are provided by the air quality sensors deployed throughout the environment. As such, the system takes the overall spatial patterns of the concentration field from the annual average map, which acts as a climatology (essentially a long-term mean), and adjusts this field based ...
