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.
An Overview of the News
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.
Air pollution status in Kolkata:
Kolkata is facing severe air pollution, which is mainly driven by pollutants like PM2.5.
Recent AQEWS measurements show that the AQI is 74, which is expected to rise above 170 by 30 August.
These forecasts highlight the urgency of tackling air pollution and emphasize the role of early warning systems.
Data Integration and Accuracy:
AQEWS integrates data from the National Air Quality Network and satellite sources to generate accurate air pollution forecasts.
The accuracy of the system was proved during the experimental phase that started in September 2022.
The inclusion of data from 420 air quality monitoring stations across India ensures a comprehensive approach to the assessment of air quality.
