SmogRank is an air-quality information platform that tracks and compares PM2. 5 pollution across cities worldwide. Its live ranking covers 2,934 measured cities in 82 countries, ordering them from the most polluted to the cleanest and showing how readings compare with the World Health Organization’s 24-hour guideline.
Visitors can explore current conditions through a live map and rankings, compare two cities, and review pollution history through rolling 24-hour, 7-day, and 30-day views, as well as yearly, monthly, weekly, and daily boards. City listings include PM2. 5 measurements, US Air Quality Index values, changes in rank, and indicators of how many times readings exceed the WHO guideline.
SmogRank also explains its data markers and air-quality scales, distinguishing readings supported by multiple sites, a reference monitor, or low-cost sensors. The site notes when monitoring data is unavailable, making clear that missing cities should not be interpreted as having clean air. By bringing rankings, historical records, comparisons, and measurement context together, SmogRank helps users examine pollution patterns across locations and time periods
