Kolkata becomes the third Indian city to adopt an Air Quality Early Warning System (AQEWS)

Kolkata became the third Indian city to adopt the Air Quality Early Warning System (AQEWS) to combat rising air pollution.
The system, developed by the Indian Institute of Tropical Meteorology (IITM) in Pune, aims to address rising air pollution levels in urban areas.
AQEWS in Kolkata uses an advanced sensor network to provide real-time monitoring of the Air Quality Index (AQI).
AQI is a standardized measure of the level of air pollution, with a value ranging from 0 to 500.
The system focuses on PM2.5 (particles with a diameter of 2.5 micrometers or smaller) levels, which is a major contributor to health problems due to its ability to enter the lungs.
