NCR’s air data crisis: Haryana AQI systems non-functional, state relies on Delhi’s info to monitor its own air; Gurgaon flies blind

Haryana's air quality monitoring has been severely compromised since April, with all 29 state pollution control board stations offline due to a lapsed maintenance contract. This leaves the region pollution-blind, relying solely on two India Meteorological Department stations for data. The lack of comprehensive monitoring undermines efforts to mitigate air pollution during peak periods.
