Aviation Services Division

Servicing aviation needs under International Civil Aviation Organisation (ICAO) regulations is one of the most important tasks of Met Éireann. A substantial part of our resources is dedicated to this task, with a corresponding proportion of our budget being recouped on a cost recovery basis through route charges.

Met Éireann’s Aviation Services Division (ASD) core function is to provide or arrange for the provision of operational aviation related weather information.

These meteorological services are governed by ICAO standards and, also, European Single European Skies Regulations.


The primary consumers of ASD services include the Airlines, Air Traffic Control, and Airport Authorities, Search and Rescue services and general aviation.

Under ICAO obligations the ASD must also ensure the maintenance of a ‘meteorological watch’ over Irish airspace to warn of phenomena that are hazardous to aviation.  This involves observations at airports and aerodromes by experienced observing staff. The following image shows the airspace that Met Éireann maintains weather watch for; the Irish Flight Information Region (FIR).

Aviation Products

Aviation forecasters will periodically issue a number of forecast products:

Terminal Aerodrome Forecast (TAF)

This contains weather information for airfields in a concise code format and it includes the wind, prevailing visibility, significant weather, cloud and expected significant changes in the weather

Meteorological Terminal Aviation Routine Weather Report (METAR)

This includes data for the temperature, dew point, wind, precipitation, cloud information, visibility and pressure

Significant Weather Chart (SIG WX)

These graphical products which are created by the Aviation forecaster illustrate the areas of main meteorological concern. The map gives a snapshot of fronts and areas of weather. The chart relates to all weather below 10,000 feet and is divided up into areas. It displays details of visibility, weather, cloud, icing and turbulence

Significant Meteorological Information (SIGMET)

A SIGMET is a weather advisory that contains meteorological information concerning the safety of all aircraft. The advisory can cover events such as thunderstorms, severe turbulence, severe ice, severe mountain waves, and volcanic ash for example.

Daily specialised forecasts for Irish Airports

Met Éireann also provides detailed daily forecasts for some of the airports in Ireland. These specialised forecasts provide more detail as well as a longer time frame for the possibility of icing, snow etc

Aviation Services

In addition to the regulated services, ASD also provides/arranges for the provision of bespoke products to further assist the aviation community in its operations and decision making processes. The ASD is accredited to an ISO Quality Management System standard.

Aviators can avail of aviation briefings from Met Éireann’s Aviation Forecasters by dialling 1570 234 234. Calls cost a maximum of €2.40/minute. The rate charged will depend upon the phone service provider, but it cannot exceed €2.40/minute.

Met Éireann via the ASD provides a free web-based Met Self Briefing (MSB) service for the provision of aviation data (Meteorological Terminal Aviation Routine Weather Report METARS and Terminal Aerodrome Forecasts TAFS etc) to pilots and aviation customers (https://briefing.met.ie/).

Meteorological Services for the Defence Forces and meteorological training are provided at Casement Aerodrome.

Met Éireann is in the process of upgrading its aviation observing systems through a project called the Aviation Modernisation and Automation Project (“AMAP”). The project will modernise Met Éireann’s aviation surface observation network, and with the exception of Dublin, automate aviation surface observations. This goal is primarily driven by the requirement to provide safe and effective observations which meet all EU and International Civil Aviation Organisation (ICAO) standards.
