01

What is CityAir?

CityAir is a real-time air quality monitoring service. CityAir can be used for various types of industrial, governmental and environmental monitoring, in research, or simply out of curiosity and to learn more about the environment.

02

Who develops CityAir?

The CityAir project was initiated by Tion, a Russian technology company. It is an independent project that is being developed in partnership with the Uniscan Research engineering company. Methodical support is provided by the Academlab analytical laboratory.

According to the WHO, more than 90% of the Earth’s population breathe dirty air every day. This directly impacts the health and life expectancy of people. At the same time, air quality monitoring systems cover only small areas of the planet. We created CityAir to change this situation.

03

What does the CityAir map show?

CityAir shows air pollution and weather data in the areas where monitoring stations are installed. With a substantial number of stations, modeling can be used to build a continuous map of air pollution.

The CityAir public map is so far an open experiment. All data published in the service are purely experimental. We keep monitoring the performance of our stations and refining our forecasting algorithms and interfaces. We have intentionally made the data publicly open already at this stage in order to check the usability of our interface and to collect feedback from the first users.

For corporate customers, we develop customized interfaces for data presentation.

04

What is the Air Quality Index?

The Air Quality Index (AQI) is a general indicator of air pollution based on the concentration data on a number of pollutants. CityAir calculates the AQI according to the most common international methodology.

05

Which indicators are used to measure the level of air pollution in the city?

The main indicators reflect the concentrations of different types of dust, mainly the particulate matter PM2.5 (particles with a diameter less than 2.5 μm) and PM10 (particles with a diameter less than 10 μm).

PM2.5 particles are the most hazardous to humans as they have a high penetrating ability due to their small diameter. They are generally not intercepted by any natural barriers and easily penetrate into the body. A continually high PM2.5 content in the air has a negative impact on health.

06

Where is CityAir currently used?

The public CityAir map displays data from several experimental stations in Novosibirsk, including Academgorodok, and in Moscow, including the territory of the Skolkovo innovation center. In the future, in addition to CityAir stations, data from existing mobile laboratories and (semi-)automated posts may be added to the map. We have also implemented a number of projects for our corporate customers.

07

When will a CityAir station be installed in my district/city?

We know that many people are concerned about the air quality in their districts and cities. Unfortunately, at the moment we do not have the capacity to roll out full-fledged air quality monitoring systems in cities but we are demonstrating the capabilities of our service and actively searching for potential partners, especially in those districts and cities where the problem is most acute.

08

Can I buy CityAir stations?

Yes. Our stations measure PM2.5 and PM10 content levels, atmospheric pressure, humidity and air temperature.

CityAir stations that also measure the content of certain gas pollutants in the air are currently under development. We will announce their specifications and the start of sales at a later date.

09

CityAir shows that the air is polluted in my district. Is it dangerous?

You should not rush to hasty conclusions. The right answer to this question requires long-term monitoring of air pollution as well as of health.

It should also be taken into account that we spend more than 90% of our time indoors. There are various efficient and affordable solutions for ventilation and air-purification in rooms, which can partially compensate for the negative impact of the environment in your district.

10

What is the main source of air pollution in a modern city?

Fuel combustion products (for example, exhaust gases produced by cars and fossil-fuel power plants) are the main pollution factors in modern cities.

Other sources of air pollution are construction sites, quarries, coal discharge ports, and waste incineration facilities.

There are also sources that are not human-induced (i.e. natural sources of air pollution), such as soil, sea salt, pollen, mold spores, etc.

11

Where else can I learn about air pollution
in Russia?

The Ministry of Natural Resources and Ecology issues environmental reports that include information about air quality in Russian cities. Annual reports on the air conditions across Russia are available from the Meteorological Office (Roshydromet).
