Noida AQI works by measuring the air quality in the region, taking into account various pollutants such as particulate matter, nitrogen dioxide, ozone, and others. The AQI is typically categorized into different levels, ranging from good to severe, based on the concentration of these pollutants. However, the specific details of how Noida AQI works are not provided in the given evidence. The article mentions that the AQI is getting worse, but it does not explain the technical aspects of how it is measured or calculated.
The article does mention that road widening work in Greater Noida is spewing dust, which can contribute to poor air quality. However, it does not provide any information on how the AQI is affected by this specific factor. The article’s focus is on the impact of road widening work on air quality, rather than explaining the technical workings of the AQI system.
It is worth noting that the article does not provide any detailed information on the AQI system, its measurement methods, or its categorization levels. Therefore, any attempt to explain how Noida AQI works would be speculative and not grounded in the provided evidence.
