The service provides the latest METAR, TAF, and SIGMET reports in IWXXM for Irish aerodromes in compliance with ICAO Annex 3 and PANS-MET, Document 10157. The retrieval of information will be done on a regular basis (subscription) via AMQP 1.0 whereby the message contains the whole IWXXM dataset. The other option to collect the data is via Request/Reply using OGC EDR API, where the IWXXM data is provided in replies, in a ZIP archive.

This service satisfies these by offering meteorological information as regulated by Commission Implementing Regulation (EU) 2017/373 of 1 March 2017 and ICAO Annex 3. The scope of the meteorological information satisfies the EU Implementing Regulation 2021/116 - Common Project One.
Information Exchange Requirements
IER 1 - The information currently included in the METAR reports as defined in Commission Implementing Regulation (EU) 2017/373, ICAO Annex 3 Amdt 82 and PANS-MET.
Capabilities
The service provides high quality, up-to-date, trusted, regulated meteorological information in digital form for use by service consumers within the aviation domain.
Distribute Data
The service distributes the data according to the stored subscriptions and topics.
Information has been shared; the service consumer gets the requested data.
Request Data
The consumer is able to request the data using OGC EDR.
Information has been shared; the service consumer gets the requested data.
Subscribe to Data
The user is able to subscribe to data via AMQP by connecting to the predefined topics.
Subscription has been established, consumer will receive data matching the subscription.
-
Time Behaviour
METAR and SIGMET: Under normal operations 90% of messages will be delivered within 10 minutes after the issuing time.
-
CapacitySubscriptions are managed with consideration of the capacity of the technical infrastructure. Each connection is rate and connection limited to avoid overload of the system.
-
Availability98% System Uptime
-
RecoverabilityOn switchover of the hot-standby HA cluster the status of the database and queues is preserved
-
IntegrityIntegrity is protected by using TLS layer for all the service interface bindings. However the Message Security based on S/MIME 4.0 proposed in SWIM TI Yellow Profile 2.0 is not yet implemented.
-
ConfidentialityData delivery is only available for registered users, who need to present their username and password for access to the services using HTTP Authorization header with Basic scheme for HTTP based connections, and using SASL plain for AMQP connections. Users connecting to the public interfaces must present a valid EACP client certificate, which must be further whitelisted in the service based on the details of the Distinuished Name portions of the client certificate such as Common Name, Organisation, Email.
-
General Terms and Conditions of Business
TBD
-
Information RetainmentMeteorological information is retained for a period of at least 30 days from the date of issue. This relates to the information itself and not the request time of the user.
-
SubscriptionTo subscribe, customers need to contact [email protected] and request access to the service.
-
AuthenticationThe service ensures client authentication in accordance with SWIM Technical Infrastructure (TI) Yellow Profile 2.0 requirement SWIM-TIYP-0042 by implementing username and password authentication using HTTP Authorization headers with Basic scheme for HTTPS based interfaces, and using SASL PLAIN for AMQP. Users connecting to the public interfaces must present a valid EACP client certificate, which must be further whitelisted in the service based on the details of the Distinuished Name portions of the client certificate such as Common Name, Organisation, Email. The service ensures server authentication in accordance with SWIM-TIYP-0042.
-
AuthorisationThe service ensures that satisfactory authorisation is put in place according to EUROCONTROL Specification for SWIM Technical Infrastructure (TI) Yellow Profile requirement SWIM-TIYP-0070.
-
ConfidentialityThe service ensures point-to-point confidentiality in accordance with EUROCONTROL Specification for SWIM Technical Infrastructure (TI) Yellow Profile 2.0 through the use of Transport Layer Security (TLS) 1.3. The communication is encrypted by TLS with a certificate issued by the EACP.
-
IntegrityThe service ensures point-to-point integrity in accordance with EUROCONTROL Specification for SWIM Technical Infrastructure (TI) Yellow Profile through the use of Transport Layer Security (TLS) 1.3.

Filtering Capabilities OGC EDRThe EDR implementation builds on MET3SG community MET SWIM OGC EDR GUIDANCE. Additionally it supports OGC EDR filtering machanisms: cube query using a bbox parameter, area query with a polygon specified in coords parameter, radius query.
-
Filtering Capabilities AMQPSimple filtering is achieved using the topic structure of the broker, which determines the type of data recieved. AMQP SQL-like syntax for filters applied to AMQP application properties can be also used by the service consumer to further filter the data received.
-
The service provider ensures that the data offered within this service is created by MET Eireann, a REGULATED_METEOROLOGICAL_SERVICE_PROVIDER.

Typical Request/Reply Behaviour
The typical behavior is following:
- Client sends request to the OGC EDR interface
- The service replies with the appropriate HTTP response
- If the request for specific IWXXM data is made, the service returns a zip archive with one or more files containing IWXXM messages.
-
Typical Data Distribution BehaviourThe service sends the data to subscribers when they are available and match their subscription using the AMQP protocol.
-
Typical Data Subscription BehaviourTo subscribe to data, the consumer needs to contact the Service Provider and request the credentials. After registration, the consumer is provided the endpoints of both EDR and AMQP interfaces
-
<p>For AMQP subscriptions, regular heartbeat messages are sent to weather.aviation.metar topic at approximately 60-second intervals. Arrival of the heartbeat message indicates that the main subsystems of the service are running.</p>
