Learn how community groups in Bengaluru are working with Clarity monitor fine particulate matter and improve pollutant levels. Working with Clarity to implement better air quality monitoring infrastructure has truly spurred a revolution in the way Bangalore thinks and acts on air pollution issues.
Hailing from Greece, Sotirios Papathanasiou is an air quality expert. His blog, See The Air, focuses on air quality monitoring, pollution analysis, and activism pushing cities around the world to concentrate on clean air.
Mean Absolute Error (MAE) is calculated to determine the absolute difference between the measurements of a device under analysis and the measurements of a reference instrument. It is the average of the absolute value of the deviations between measurements of the two devices. In other words, it shows how different measurements from the two devices are in value.
The Pearson squared correlation coefficient (R²) is calculated to determine how measurements from a device under analysis correlate with measurements of a reference instrument, or in other words, how well the device under analysis measures changes in pollutant concentration compared to the reference instrument.
We now have smart homes and smart cars, so it’s no surprise that our cities are becoming smarter every day. One problem plaguing many big cities is air pollution, and one company is using technology to help remedy the problem.
