city_air | PM2.5 now in a city: the latest hourly value, its 24-hour, 7-day, 30-day and year-to-date averages with its rank among all measured cities, the US EPA category, how it compares with the WHO guideline, and the "why it ranks here" notes (patterns in its own history and nearby fire, smoke and volcano evidence, named as likely causes, never confirmed), and the local hours its air was usually worst and params: city* |
