3 Truths of the IQAir index of air pollution in Tehran Should we monitor the air quality from the Swiss system or from the Tehran Municipality website?
With the beginning of the main air pollution season in Tehran, instead of focusing on the air quality index of the "Tehran Municipality", the eyes of the Tehranians are staring in two directions.
Milad Tower and IQAir.
Tehran's air quality has "declined markedly" since the end of last week, when a low-altitude layer of "smog" formed in the city's skies on Wednesday, and the concentration of pollution rose on Thursday and Friday.
The citizens of Tehran "in recent days" turned to two places for "momentary information" about the amount and intensity of air pollution.
The Milad Tower Index is a visual indicator for most Tehranians to "diagnose" air pollution. Since this structure can be seen from almost all parts of the city, as soon as "the concentration of air pollutant particles increases", the degree of transparency of its visibility also changes.
But many citizens refer to the IQAir index in Tehran's polluted months. The IQAir index is a global platform for immediate and daily publication of "air pollution" in at least 9,000 cities around the world, which was launched about 50 years ago by a private company in Switzerland.
There are 3 facts about the information that the IQAir index publishes about Tehran's air pollution on an hourly and daily basis, knowing them can increase the rate of "citizens' perception" of this index's data, more details on the Housing Market Observatory channel.
