Get an AirVisual Outdoor and contribute to collecting millions of data points for the Bogor map to track local air pollution
At the top of the main city page for Bogor, the viewer will see the air pollution map. Clicking on this will encourage a new page to open which will be filled with all the available information about the air quality.
Once the new page opens, the first thing to notice will be the overall colour of the map. This is a direct reflection of the current air quality. The standard colours are used across the entire IQAir website and can range from pale green to dark maroon. As the colours get darker, the air quality worsens.
Whilst looking at the air pollution map for Bogor, there will be several coloured discs or circles distributed across the screen. These represent the sites of the ground-level air monitoring stations although they are not all under the control of the city. Each of these areas can be explored further by choosing the disc so that a new page will open specific to that locale.
At the centre of each of the discs is a number which is the United States Air Quality Index reading or US AQI for short. This figure is calculated by taking the measurements of six of the most prolific pollutants found in the city air. It is then used as a standard when comparing air quality in different locations across the world. The whole system is encouraged by the World Health Organisation (WHO).
Referring back to the main city page, it can be seen in the coloured banner across the top of it that in mid-March 2023, Bogor was enjoying a period of “Good” quality air with a US AQI reading of 19. The main pollutant was found to be PM2.5 with a recorded level of 4.5 µg/m³, which is slightly below the suggested target figure of 5 µg/m³ as recommended by the WHO. The coloured banner itself visually reveals the current air quality.
Immediately below the air quality map for Bogor is the number of contributors there are that supply the data about air quality and the number of sites they operate. Currently, there are two contributors that operate three stations. Two of them are under the control of the government department of the Indonesian Meteorology, Climatology, and Geophysics Council, whilst the other is run by an individual person.
There is much more information about air quality on the air pollution map for Bogor but the page needs to be viewed in full-screen mode so that all the information is visible. This is very easy to achieve by selecting the icon at the top of the page which will automatically open a new one at maximum size.
When the full screen is open, there will be four options appearing on the left-hand side which can each be turned on and off to see the effects they have on the map.
The first option reveals the sites of the ground-level monitoring stations which can each be explored further by selecting the appropriate disc which will open a new page with more information about that specific area.
The next option shows the possible positions of any wildfires there are that might be burning in the area. During March 2023, there were no icons on the map which meant there were no reported fires in the area. If fires are detected, then option four needs to be looked into because it shows the speed and direction of the prevailing winds and will indicate where the smoke might blow.
Option number three greatly affects the map because it changes the background colour to reflect the current state of the air. Some users may find this unusual and distracting on a map, in which case, it can be deactivated so the colours will return to a more neutral shade.
There are even more fascinating facts and figures about air quality on the right-hand side of the screen. Amongst other facts will be a table which shows the top seven most polluted cities across the globe. If this is of interest then the rest of the participating world cities can be found on a new page when the full-ranking option is selected.
Immediately below the contributor’s category is found a table that lists the most polluted area of the city according to the closest station. The current most polluted station is at Cibeureum which currently shows a US AQI reading of 45, which is classified as being “Good”.
Below that is a list of the most popular stations and the number of loyal followers they each have. The station at Cibeureum is the most popular now with almost 34,000 followers.
The source of the polluted air is not shown directly on the air pollution map for Bogor but climate change caused by the greenhouse effect is caused by several things, including transportation, industry and others. Following a recent study, it was found that over 5 per cent of all vehicles tested did not pass the desired emissions test. Using a private vehicle can indeed make the trip shorter, but the pollution it produces is also enormous. For this reason, in the future transportation must be environmentally friendly, starting from the fuel, reducing private vehicles by encouraging residents to want to ride bicycles and adding and increasing green spaces.
PM2.5 refers to atmospheric particulate matter or particulate matter. PM2.5 is a very small air pollutant, about 2.5 microns. The term PM (also called particle pollution) is a term for a mixture of solid and liquid particles found in the air. The form of these particles such as dust, dirt, soot and smoke. When viewed with the naked eye, PM 2.5 looks dark and hazy but it can be seen clearly when using an electron microscope. PM2.5 itself is made up of hundreds of different chemicals. It is formed in the atmosphere due to the reaction of chemicals such as sulphur dioxide and nitrogen oxides. This pollutant is formed from the exhaust of power plants, industry, and vehicles burning fossil fuels. PM is also emitted directly from fields, chimneys, and road construction using asphalt.
