This dataset is the estimated long-term (1981-2016) concentrations of ambient fine particulate matter across North America, which combines information from chemical transport modeling, satellite remote sensing, and ground-based monitoring. The estimates included information from updated historical emissions inventories and meteorological data, fine resolution satellite-based estimates of PM2.5, and ground-based measurements of PM2.5, PM10, and total suspended particles (TSP) measurements.

Dataset has been deposited in the Zenodo Digital Repository (DOI: 10.5281/zenodo.2616769). You can also get access to the data at this FTP site [Link]
The dataset is annual data in HDF5 format. The PM25 variable is 100 times the value we should use. So you need to read them and divided them by 100 in your code. We also have monthly data only for 1989-2016 [Link]
