Point of Contact
Situational awareness

Support situational awareness of flight crew members, operators, and other aviation entities based on up-to-date weather conditions (As required by ICAO Annex 3 chapter 9.1 and Regulation 373/2017), including information about radioactive clouds.

Meteorological information exchange

Exchange of meteorological information in aviation context, satisfying the EU Implementing Regulation 2021/116 - Common Project One, Regulation 373/2017, ICAO Annex 3 and PANS-MET.

Usage policy

Any service consumer must operate within the aviation domain. Sharing obtained information with users outside the aviation domain, without explicit authorization from the service provider is not allowed.

Real-time information

Only the latest/currently valid MET reports are available using the WS_LIGHT interface. For the AMQP interface, new reports are continuously published when available. Historical data is not retrievable.

Load restrictions

Service consumers are not allowed to impose undue loads on computer and network resources, for example, by polling at a higher frequency than the data is normally provided.

AVAILABILITY

99.95 % outside the planned outages Schedule of planned outages

ICAO location

Data is filtered by ICAO location (aerodrome/FIR). In WS_LIGHT as a query parameter, in AMQP by queue name.

MET data retrieved from existing compliant MET systems provided by the Danish Authorities.
Encryption

All communication is encrypted using TLS 1.2 or above

Normal Conditions

The service provides an AMQP 1.0 and a WS_LIGHT based Service. The service message exchange patterns are (for REST Based WS_LIGHT Services) - SYNCHRONOUS_REQUEST_REPLY, and PUBLISH_SUBSCRIBE_WITH_PUSH_MECHANISM for AMQP services.

AMQP interface

Will publish and provide MET reports to relevant message queues as they become available.

WS_LIGHT interface

Will respond to MET report requests (provider). Errors will be returned with appropriate HTTP Status Codes and XML-formatted ProblemDetails message body.

MET Data Subscription

Describes how to subscribe and unsubscribe to information for the AMQP Service Distribution interface

MET Data Distribution

AMQP Interface to continuously retrieve MET reports based on subscriptions

AMQP Broker
