Concerns are mounting over the accuracy of Delhi's air quality monitoring as ground checks reveal questionable practices.

Delhi's air quality dramatically improved, dropping from a three-year October high to 'moderate' levels. This significant shift, without rain, has experts puzzled. The government credits extensive enforcement teams, anti-smog guns, and road sweeping. While meteorological factors like lower humidity and wind shifts played a role, the full reasons for this sudden improvement remain under investigation.

Delhi's ambitious cloud seeding project, costing over 3 crore rupees, has failed to produce significant rainfall. Three trials were conducted with little to no rain, leaving experts questioning the initiative's value. Scientists point to the dry winter air as a major obstacle. Experts emphasize that such costly, temporary measures distract from addressing the root causes of pollution.
