How does the AirVisual Air Quality Index Checker Work

Although this fact should not be so surprising, given a large number of motorized vehicles that crowded the streets of the capital every day and the lack of green open space, still citizenship seemed surprised by this fact.

Air quality data and a number of other cities are increasingly milling around in the timeline. Not only on Twitter, where this issue first came up, Facebook and Instagram users were also infected by spreading this screenshot.

AirVisual Data Sources

Then where and how is the air quality index calculated? On the official website of AirVisual, the weather data, quality data from the government and local location nodes and satellite data are data sources that are then processed with artificial intelligence technology.

Processes that involve artificial intelligence technology include data validation and modeling. Then the output of the process is the data available on the AirVisual application along with the API, real-time data modeling and AirVisual Node air quality monitoring devices.

On its official website, AirVisual mentions reported air quality data from several sources, including ground-based monitoring stations, which are generally government-owned monitoring stations or community-based Pro AirVisual air monitoring stations.

The stations measure and report the air quality captured by the physical sensors installed. This data source is then listed on the data that the AirVisual application and website reports.

In Indonesia, several stations that are the source of AirVisual data are located in Ubud, Pekanbaru, Palembang, Samarinda, and others. Especially, the stations are located at the United States Embassy, ​​Pejaten, BSD, Rawamangun, Mangga Dua and Pegadungan.

Air Quality Index System

The AirVisual air quality index translates to a measure of the concentration of pollutants that is sometimes confusing, into one easy to understand scale. Generally, 6 main pollutants, namely PM2.5, PM10, carbon monoxide, sulfur dioxide, nitrogen dioxide and ozone in the earth’s surface, are considered in calculating the index.

This index ranges from 0 to 500. The higher the index value, the higher the level of air pollution and the potential health effects. An index value greater than 300, for example, is considered dangerous, while an index value between 0 and 50 indicates good air quality.

There are several air quality index calculations. The calculation of the Chinese and American indices is most widely used and AirVisual applies the United States index calculation.

Both the calculation of the Chinese and US indices are calculated taking into account the six main pollutants mentioned above. The results of both are only different in the index score of 200 and below.

Because the American index system produces higher scores for indexes below 200, it is considered to be more stringent. Therefore the American index system is widely used.
