Use of ObservedLayer

[joergklausen]

Summary and Purpose

Support for elements from the code table ObservedLayer is proposed. If approved, the specification of the WMDR XSD shall be updated accordingly. Parsers claiming compliance need to be extended.

Proposal

Use the O&M OM_Observation element 'parameter:NamedValue' to specify the ObservedLayer, as illustrated below.

<om:parameter>
   <om:NamedValue>
      <om:name xlink:href="http://codes.wmo.int/wmdr/ObservedLayer" />
      <om:value xlink:href="http://codes.wmo.int/wmdr/ObservedLayer/freeTroposphere" />
   </om:NamedValue>
</om:parameter>

Reason

For some remote-sensing observations, but also in-situ observations, the observed layer is an important attribute describing the observation. To facilitate this, a corresponding code list has been introduced (see ObservedLayer). The WMDR specification does not currently support this and will need to be updated after approval. Subsequently, parsers claiming compliance with the WMDR XSD will also need to be extended.

Expected Impact of Change

HIGH: update of WMDR XSD specification and subsequently of any parser claiming compliance (e.g., OSCAR/Surface).
