CERES Surface Type Data

The surface type microsets found on the Data Access page were created from original CERES data by the ASDC. Each data entry represents a one degree latitude by one degree longitude grid box on the surface of the earth (the data point is the upper-left corner of the grid box). The data is representative of biome types observed during 2000. These data are not intended for the study of land use changes over time, but offer a snapshot of the Earth’s surface.

Eighteen surface/biome type categories used by CERES are:

1. Evergreen Needleleaf Forest
2. Evergreen Broadleaf Forest
3. Deciduous Needleleaf Forest
4. Deciduous Broadleaf Forest
5. Mixed Forest
6. Closed Shrublands
7. Open Shrublands
8. Woody Savannas
9. Savannas
10. Grasslands
11. Permanent Wetlands
12. Croplands
13. Urban and Built-up
14. Cropland Mosaics
15. Snow and Ice (permanent)
16. Bare Soil and Rocks
17. Water Bodies
18. Tundra

Surface/biome types 1 – 17 correspond to those defined by the International Geosphere-Biosphere Programme (IGBP). An additional surface/biome type was defined for CERES. Surface/biome type 18, Tundra, occurs when a location has an IGBP surface/biome type of 16 (bare soil and rocks) and the Olson vegetation map identifies the same location as Tundra.
