Properties

Optional maxValue

maxValue?: number

The maximum value of a range of measured values.

Optional minValue

minValue?: number

unitCode

unitCode: string

A unit of measure, in the format "unit" or "namespace:unit".

Units with the namespace "wmo" or "wmoUnit" are defined in the World Meteorological Organization Codes Registry and should be canonically resolvable to http://codes.wmo.int/common/unit/{unit}.

Units with the namespace "nwsUnit" are currently custom and do not align to any standard.

Units with no namespace or the namespace "uc" are compliant with the Unified Code for Units of Measure syntax. This also aligns with recent versions of the Geographic Markup Language (GML) standard, the IWXXM standard, and OGC Observations and Measurements v2.0 (ISO/DIS 19156).

Namespaced units are considered deprecated. NWS will be aligning the API to use the same standards as GML/IWXXM in the future.
