AQI Noida works by monitoring and reporting the air quality in the Noida region. The system tracks various pollutants such as particulate matter, nitrogen dioxide, ozone, and sulfur dioxide to provide an accurate reading of the air quality index (AQI). However, the evidence provided does not go into the technical details of how AQI Noida operates. It only mentions that the air quality index is getting worse in Greater Noida due to road widening work that is spewing dust.
The Times of India article does not provide information on the specific technology or methods used by AQI Noida to monitor and report air quality. It only reports on the current air quality situation in Greater Noida and its impact on the residents. Therefore, the exact process of how AQI Noida works remains unclear based on the provided evidence.
