Delhi Diwali Pollution Potentially 49% Higher Due to Missing Data

Delhi's Diwali night pollution readings were likely distorted due to missing PM2.5 data from monitoring stations. Research by the Centre for Research on Energy and Clean Air suggests pollution levels could have been up to 49% higher. The Central Pollution Control Board cited calibration issues, while Delhi Pollution Control Committee readings were inconsistent. This highlights a significant data gap in assessing air quality during critical periods.
