The spatial data are provided in GRID (zipped ArcInfo workspaces) and compressed GeoTIFF formats. The grids are stored in geographic coordinates with the following parameters:
Units: Decimal Degrees
The grids have a resolution of one-quarter degree (0.25 decimal degrees), or approximately 28 km on a side at the equator.
