City air quality forecast
Forecast a city's daily air quality a few days ahead, including season and festival effects.
The brief
Cities need warning before bad air days so schools and hospitals can prepare. Forecast daily AQI a few days ahead with seasonal, weather and festival effects, and test it against a simple baseline. Good looks like: forecasts that beat persistence, back-testing over a year, and accuracy on the worst days reported.
What you will build
- Prepare daily AQI series for a city
- Add season, weather and festival features
- Compare persistence, Prophet and gradient-boosted forecasts
- Back-test over a year
- Report accuracy on the worst days
