Interesting question. One of the most important parts of building a successful machine learning model is the quality and quantity of the data. You can gather a clever set of features such as longitude, latitude, day of year, season, time of day, wind speed, temperature, etc. But in the end you will be using historical data - which is very limited. At the same time, the earth system is extremely complex and responds abruptly to changes within the system which are highly non-linear. Therefore I would be very cautious when applying ML to any kind of forecasting that has to do with air quality.

Due to more than 10-15 input parameters being present , overfitting would be an issue . Care must be taken in distinguishing overfitting with good prediction .
