Ontologies for Earth system science

Controlled vocabularies are convenient for associating measured parameters with standard names. Ontologies expand the capabilities of controlled vocabularies by providing more descriptive semantic power. For example, ontologies enable descriptions such as: 1) for “surface” temperature, express the actual height above the ground; 2) for “Deviation from the average”, describe the actual climatology the average is based upon; 3) for web services, provide service descriptions and limitations.
