Entry ID:
MEAR_30
Summary
Abstract:
The dataset is a subset of the aridity zone map created by CRU/UEA, UNEP/GRID for the World Atlas of Desertification. Aridity zones were derived from an Aridity Index (AI) which is calculated as the ratio of precipitation to potential Evapotranspiration. Zones included in this dataset are: hyper arid, arid, semiarid, and dry sub humid.
Purpose: The dataset has been developed to define the Millennium Ecosystem Assessment (MA) dry land system boundary.
