Particulate matter (PM) is one of the most dangerous air pollutants. PM is measured as PM2.5 and PM10, where 2.5 and 10 are the maximum diameters of the particles. PM2.5 is much more expensive to measure compared with PM10. Hence, it is important to estimate the PM2.5 concentration for the areas where the measurements do not exist. Statistical methods are vital in prediction air pollution data. We will briefly introduce the PM data collected at four sites of Auckland by the National Institute of Water and Atmospheric Research (NIWA), then illustrate the prediction of PM2.5 concentration by using the matching pursuit algorithm (MPA). Novel stopping rules for MPA, based on information theoretic criteria, will also be discussed (Li et al. 2018).
