Definition note 2

reference temperature for a conventional or calculated quantity value

Referenztemperatur für einen konventionellen oder berechneten Wert.

Per Konvention gilt für Temperaturangaben mit diesem refType die ITS-90-Skala. Temperaturen, für die eine andere Skala (z.B. IPTS-68, PLTS-2000) gilt, müssen mit einem zusätzlichen refType temperature_ (siehe dortige Definitionen) versehen werden.

The ITS-90 scale applies to temperature data with this refType by convention. Temperatures for which a different scale (e.g. IPTS-68, PLTS-2000) is applicable must have an additional refType temperature_ (see definitions there).

Usage of this refType on dcc:metaData is deprecated - refType should rather be used on a dcc:quantity element inside a dcc:metaData element with refType basic_referenceConditions

Die Verwendung dieses refType an dcc:metaData ist veraltet - refType sollte bevorzugt an einem dcc:quantity-Element innerhalb eines dcc:metaData-Elements mit refType basic_referenceConditions verwendet werden.
