We are happy to introduce a new version of the metObs API, which provides free and open access to DMI’s meteorological observation data. The new version is aligned with the services for oceanographic observation data and lightning data, and follows the OGC API - Features standard. The release consists of: - MetObs v2 API
- MetObs v2 Bulk Download Service
- Technical documentation
Main differences between metObs v1 and v2 are: - metObs v2 is similar to the other DMI open data services - uses same data schema as oceanObs v2 and lightningdata v2.
- metObs v2 API follows OGC API Feature standard
- time formats are RFC3339
- result set has 'next' link to next page in results
- metObs v2 results are not sorted unless requested via sortorder
- metObs v2 supports queries based on bounding box - see bbox parameter in the Request and Response Examples
- metObs v2 does not support sorting in ascending order (this has to be done by client)
- Observations return GeoJSON with the geometry property set for applicalble data (this makes it possible to immediately see from where the observation came without querying the station list)
- in metObs v2 the datetime parameter includes both the ‘to’ and the ‘from’ endpoints, where in metObs v1 the ‘from’ parameter was included and the ‘to’ parameter was not
- metObs v2 does not return 204 on empty results. Empty results are 200 OK, but with empty feature list and numberReturned = 0.
- metObs v2 stations list contains station history – see more on the Station specific Request & Response examples page
- metObs v2 parameter list endpoint has been removed - see list here
A 6-month transition period is planned, where both metObs v1 and v2 services will be active. MetObs v1 will be retired on August 31st 2021. |
