All IMD Air Quality Monitoring Stations In Delhi Offline: Think Tank

The IMD said the AQMs are functional but data is not being relayed to the central server due to a technical issue.

None of the eight air quality monitoring stations (AQMs) of the India Meteorological Department (IMD) in Delhi has relayed data to the central server in the last two months, the Centre for Science and Environment said on Friday. The IMD said the AQMs are functional but data is not being relayed to the central server due to a technical issue. "Even though Delhi's monitoring network grew to 40 stations by the end of 2020, the number of active stations has reduced to 32 as all the IMD stations have gone offline," the CSE said. The IMD's station at Burari crossing has been offline since December last year, while the Ayanagar, CRRI Mathura Road, IGI Airport, Lodhi Road, North Campus DU, and the PUSA stations went offline on March 10, it said.
