* When authors make use of data they should cite both the data set and the scientific publication, if available. Such a practice gives credit to data set producers and advances principles of transparency and reproducibility. Please visit the data citations page for details. Users who would like to choose to format the citation(s) for this dataset using a myriad of alternate styles can copy the DOI number and paste it into Crosscite's website.
† For EndNote users, please check the Research Note field for issues with importing authors that are organizations when using the ENW file format.
Each file contains floating point values estimating PM 2.5 concentrations. The raster grids have a grid cell resolution of 0.01 degrees and cover the global land surface from 70 degrees north to 55 degrees south. Individual files in the table below are zipped GeoTIFF files approximately 90-100MB in size.
