Meteorological factors like temperature, humidity, and rainfall affect air quality in cities. A study in Dhaka, Bangladesh looked at how these factors relate to air pollutants like sulfur dioxide and particulate matter. They found that sulfur dioxide levels are rising, while others are falling. Most pollutants decrease when it's hotter and less humid, but their levels vary with the seasons. Models can predict particulate matter levels well, but struggle with gases. This research helps improve air pollution forecasts in changing weather conditions.
