The files for this data set are available as global rasters in GeoTIFF, ASCII (text), and netCDF format. The ASCII and GeoTIFF data are available at the native 30 arc-second resolution and four lower resolutions: 2.5 arc-minute, 15 arc-minute, 30 arc-minute, and 1 degree. NetCDF files are available at all resolutions except 30 arc-second. The data are stored in WGS84, geographic coordinate system (latitude/longitude).
Each downloadable is a compressed zip file containing either the global GeoTIFF or ASCII for the year and resolution of the estimate, or the netCDF containing all years of the estimate at a selected resolution, as well as data quality layers and ancillary files. A separate documentation zip file contains PDF documentation, a Microsoft Excel file (.xlsx) with country-level information and sources, and a text file (.txt) with a log of changes to the data set by version.
The netCDF file format is only available for the All Years Combined category and is not available at 30 arc-second resolution.
