After Delhi-NCR which recorded ozone exceedance on almost all days of this summer, Mumbai with 75 days of exceedance was the second-most impacted metro.
The summer of 2022 -- one of the hottest in history -- has witnessed widespread ozone exceedance, making the air of Delhi-NCR more toxic, according to an analysis conducted by the Centre for Science and Environment (CSE).
The think tank's assessment is based on the publicly available granular real time data (15-minute averages) from the Central Pollution Control Board of India's(CPCB) official online portal Central Control Room for Air Quality Management.
In Delhi-National Capital Region(NCR), the researchers captured data from 58 official stations.
The analysis tracked exceedances at each station. Breach of the standard by even one station is considered exceedance by the city. Days with multiple stations exceeding the standard indicates the severity of the spatial spread and number of people exposed.
