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 defined at https://unitsofmeasure.org/. 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. We will be aligning API to use the same standards as GML/IWXXM in the future. - `qualityControl` 'Z' | 'C' | 'S' | 'V' | 'X' | 'Q' | 'G' | 'B' | 'T': For values in observation records, the quality control flag from the MADIS system.
