Introduction

The Meteorological SWIM Services constitute a family of information services for:

satisfying the information exchange requirements of the EU Implementing Regulation 2021/116 - Common Project One (CP1) and the SESAR Deployment Programme by end 2025; and
the future exchange of enhanced meteorological information.

This collaborative space contains:

an entry for each information service including:
- a service definition; and
- supporting material to promote a better understanding of the service definition where needed.
"transversal" supporting material (e.g., the Meteorological SWIM Services Ecosystem) to promote a better understanding of the services as a whole.

Each service definition follows the same Service definition template . This allows them to be compared with other service definitions.

Services and their capability

The implementation of these information services provides the following capabilities:

the IWXXM METAR-SPECI Subscription and Request Service allows a service consumer to subscribe to and access to METAR/SPECIs in IWXXM format;
the IWXXM TAF Subscription and Request Service allows a service consumer to subscribe to and access to TAFs in IWXXM format;
the IWXXM SIGMET Subscription and Request Service allows a service consumer to subscribe to and access SIGMETs in IWXXM format;
the Quantitative Volcanic Ash Information Subscription and Request Service allows a service consumer to subscribe to and access relevant information related to volcanic ash.

In addition, the implementation of these enhanced information services provides the following capabilities:

the Meteorological Aerodrome Forecast Subscription and Request Service allows a service consumer to subscribe to and access relevant forecast aerodrome meteorological information;
the Meteorological Aerodrome Observation Subscription and Request Service allows a service consumer to subscribe to and access relevant observed aerodrome meteorological information.

The services design is based on some key principles.

the service definitions are standalone and independent of each other - no relationships have been defined between them;
the service definitions do not affect how the meteorological information service provider receives inputs or structures its information store.

In addition, the following assumptions are made:

the work taking place at ICAO level is to be reflected, including the discussion on the move from product-centric services to data-centric services;
the service definitions build on previous work undertaken in SESAR. They aim to reflect an agreed base that can be implemented in the 2025 time frame and also build towards enhanced services in the future.
