Full Form of AQY
What is AQY?
Air Quality Year (AQY) is a metric used to represent the average air quality over a calendar year, typically derived from daily Air Quality Index (AQI) data. In India, the Central Pollution Control Board (CPCB) and state pollution boards compute AQY to assess long-term pollution trends across cities and regions. This annual indicator helps policymakers evaluate the effectiveness of air pollution control measures, such as the National Clean Air Programme (NCAP). AQY is commonly cited in environmental reports, academic studies, and government white papers. For students preparing for competitive exams like UPSC, understanding AQY is relevant in the context of environmental geography and sustainable development. The metric allows comparison between years and helps track progress toward national air quality targets.
