City Air Quality Index

The City Air Quality Index (CAQI) is a system that measures and reports the quality of the air in urban areas. It uses various pollutants, like particulate matter and nitrogen dioxide, to provide a score that indicates how clean or polluted the air is. This score helps people understand whether the air is safe to breathe, particularly for sensitive groups like children and the elderly. A higher score suggests worse air quality, prompting individuals to take precautions, like wearing masks or limiting outdoor activities. The CAQI aims to raise awareness about air pollution and its impacts on health.
