HANPP as a Percentage of Net Primary Productivity, v1 (1995)

Data Formats

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:

Projection:    Geographic
Spheroid:   WGS84
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.
