thematicClassification

code value with no quantitative meaning, used to represent a physical quantity

physicalMeasurement

auxillaryInformation

data, usually a physical measurement, used to support the calculation of the primary physicalMeasurement coverages in the dataset (e.g. grid of aerosol optical thickness used in the calculation of a sea surface temperature product).

qualityInformation

data used to characterize the quality of the physicalMeasurement coverages in the dataset. Typically included in a gmi:QE_CoverageResult.

referenceInformation

reference information used to support the calculation or use of the physicalMeasurement coverages in the dataset (e.g. grids of latitude/longitude used to geolocate the physical measurements).

modelResult

coordinate

data used to provide coordinate axis values
