* Ecomap 2007
Domains (global) : groups of related climates differentiated based on precipitation and temperature (4 worldwide: polar domain, the humid temperate domain, the dry domain, and the humid tropical domain).
Divisions (continental) : represent the climates within domains and are differentiated based on precipitation levels and patterns as well as temperature.
Provinces (regional) : Divisions are subidivided into Provinces which are differentiated based on vegetation or other natural land covers.
Sections: subdivisions of provinces based on terrain features. Also identified are mountainous areas that exhibit different ecological zones based on elevation.
Subsections: further delination of sections
