PurpleAir publications bibliography

Here is a list of publications related to PurpleAir projects. In addition to the U.S., especially California, there are several reports from Africa, Asia, Europe and Latin America. There are some innovative methods for determining calibration factors and improving human exposure estimates using land use regression and data mining techniques. There is a special emphasis, in terms of article numbers, on wildfire exposures and levels in underserved communities (environmental justice areas)
