The Supreme Court orders probe into Delhi's AQI monitors amid data manipulation claims. Prima facie video evidence and reports alleged that sprinklers and other measures were used near monitoring stations to suppress particulate readings. The Court has directed the Delhi government, CAQM and CPCB to file affidavits on equipment, calibration, station operability and any instances of tampering. The integrity of AQI data is central to effective activation of the Graded Response Action Plan (GRAP). If monitors are shown to be faulty or manipulated, courts may order upgrades, audits, public disclosure and accountability measures.
