Tools (4)

• find_city

  Search SmogRank's cities by name, or find the nearest ones to a point. Returns each city's path for the other tools, whether it is measured by ground monitors (ranked) or only estimated from a model, and its page.

• 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). Cities without a monitor get a model estimate, labelled as one. No forecasts.

• city_history

  A measured city's daily mean PM2.5 (its local calendar days, µg/m³) and its daily rank, between two dates (up to 400 days; default the last 30), with monthly means.

• rankings

  The ranking of measured cities by average PM2.5, worst first: a rolling window (24h, 7d, 30d, year to date) or a past period (a day 2026-09-30, a week 2026-W40, a month 2026-09, a year 2025). Optionally one country.
