The service provides the latest SIGMET reports in IWXXM for Norwegian FIRs in compliance with ICAO Annex 3. Retrieval is available via (1) an OGC API - Environmental Data Retrieval (EDR) endpoint and (2) subscription over AMQP 1.0 where the IWXXM payload and message headers conform to the EUROCONTROL SWIM Technical Infrastructure Yellow Profile (Messaging).

Filtering Capabilities (EDR)Filtering is exposed through OGC API - EDR query parameters and collections, including spatial, temporal, and parameter subsetting of IWXXM-derived attributes.
-
Filtering Capabilities (AMQP)Topic-based filtering is available through the brokerâs topic hierarchy. AMQP 1.0 filters (e.g., ICAO location identifier) can be applied via standard message headers as defined by the message schema.

The service provider ensures that the data offered within this service is created by MET Norway, a REGULATED_METEOROLOGICAL_SERVICE_PROVIDER.
SIGMET (Significant Meteorological Information)
A digital aeronautical meteorological warning for en-route aircraft concerning specified significant weather phenomena, encoded and exchanged using IWXXM.

Transport SecurityAMQP uses amqps:// over TLS. SASL EXTERNAL (client certificate) may be required. Provider aims to use server certificates in the EACP chain once available. Client certificate policy for consumers is under consideration.
-
Topic StructureMessages are published under weather.aviation.{taf,sigmet}. This covers all messages in the Norwegian FIRs ENOB and ENOR.

Flow Control and LimitsDefault link credit and connection limits are to be confirmed; values will be documented in narrative connection documentation when available.
-
Typical Request/Reply BehaviourThe request is sent from the consumer to the EDR service, which processes the request and returns the SIGMET IWXXM payload. The service follows OGC API - EDR behaviour.
-
Typical Data Distribution BehaviourThe service sends data to consumers when available and matching their connection parameters using AMQP 1.0 per SWIM TI Yellow Profile Messaging.
