Air pollution is one of the great environmental problems suffered by large cities around the world today, negatively affecting the quality of life and health of people.
We can see an example in the case of Beijing where, although in 2015 it has managed to reduce its levels of pollution, there are still pollution indices that exceed five times the average recommended by the World Health Organization (WHO).
In Spain, the levels of pollution are not as disproportionate as in China, but they are not adequate either, as revealed by a study by Ecologistas en Acción. According to the document, 84% of Spaniards live in areas that exceed the WHO limits for tropospheric ozone pollution, which is especially concentrated in large cities.
So that we can be aware of the air quality around the world, Google, through the Google Earth Outreach program, has reached an agreement with Aclima, a company dedicated to the development of health technology, through which they have Integrated sensors in Street View cars in order to collect the data necessary to make a global pollution map.
In the first pilot test, which took place in Denver (USA), 150 million air quality data was collected by three cars from Google Street View in a period of just over a month.
The integrated sensors were prepared to measure chemicals that are dangerous to our body, such as nitrogen dioxide, nitric oxide, ozone, carbon monoxide, carbon dioxide, methane, black carbon, particles and volatile organic compounds (VOCs). . With this information they made a map like the one you can see below.
Google's goal is to be able to make a map of these characteristics in all cities of the world, and to achieve this they intend to acquire more environmental sensors to increase their data sources.
