WMO BUFR is a well established standard for reporting stationary weather station data.  It is very efficient set of codes as it was designed to meet very low bandwidth.  It is used operationally around the globe for reporting mandated by WMO.

BUFR may well suit requirements here, unless there is a need for web based ontology or if the weather observation is associated with a moving platform.  In which case the BUFR codes are a useful stating place may not meet those requirements.

Im not suggesting WXXM directly fits the requirements either; it quite possibly is too much.  But it does have its basis in an Web friendly ontology for observations and measurements and it does provide weather for moving objects.

I believe this standard is used for virtually all modern deployments of roadside weather stations in the US and in many other countries. While the data is not presented as an “ontology”, it is defined as an SNMP MIB within the standard and inferring the ontology is a fairly straight forward process from there.

Assuming we use OWL as the formal language, I would suggest the Ontology Definition MetaModel (ODM) provides a reasonable graphical equivalence, but I find a few of its notations rather cumbersome and unnecessarily space consuming. I am happy to consider alternatives, but I think one of our first priorities should be to decide on how we will convey the model and we should strive to be as consistent as possible.

IMHO, it is unreasonable to assume that any one standards development organization (SDO) will really own this ontology, it should be considered a public resource. From that perspective, I propose that it be permanently hosted on a public Github site and we establish rules on how we (i.e., multiple SDOs) formalize and approve content  into the “approved” branch. If the effort is to become successful, we have to have buy-in from a large community and the only way that will happen is if they all believe they have a sense of ownership and input into the final product.

Development of roadway weather observations would do well to use those mature standards as they have been deployed around the globe in sensor webs.   Unfortunately, I am not aware of an existing ontology for roadway weather observations.

The aviation Weather Information Exchange Models standards could be an input to a road surface moving vehicle weather event that included Observations and Measurements.
