The objectives

The main objective of the EUMETNET-AMDAR (Aircraft Meteorological Data Relay) Operational Service is to fulfil the requirements of the EUCOS Operational Programme for measurements of high quality upper air meteorological variables from aircraft.




The requirements

To provide:

  • Ascent/descent profiles measurements of wind and temperature at a minimum of 129 airports within the defined EUCOS Area;
  • 3-hourly profile measurements from at least 37 selected airports within Europe (between 0600 and 2400 UTC)
  • En-route and profile observations from data sparse areas having an impact on short range forecasts in Europe, to be adjusted as necessary according to the results of the EUCOS design studies (routes from Europe to North Africa, South America and Canada, over Siberia and the Arctic).
  • Observation data from outside the EUCOS area as a contribution (min 11%) to the WMO World Weather Watch Programme
  • Capability for the procurement of additional aircraft data to meet specific requirements of the Members.


The programme will optimise the data collection process to maximise cost efficiency and address the need for humidity measurements as a high priority.

The tasks

The Programme will :

  • Deliver a service that ensures the operational performance targets are met within budget.
  • Monitor and evaluate quality of the observations such that suitably quality controlled data are delivered to the GTS.
  • Work with participating airlines and manage the relationship with them, conducting regular meetings with participating airlines and other service providers as needed.
  • Carry out the Extended Humidity Trial working closely with and in support of the E-AMDAR Humidity Business Case Drafting Group.
  • Maintain the E-AMDAR infrastructure and develop it as needed to fulfil the E-AMDAR requirements.
  • Work together with the WMO Aircraft-based Observing (ABO) Programme and aircraft manufacturers (e.g. Airbus) for the benefit of the service and in order to get humidity sensors and suitable software equipped on new aircraft
  • Use every opportunity to promote E-AMDAR by describing to the aviation industry the existing and potential benefits they have (and can have) of airline observations, including humidity, for improved weather products

The organisation

The current phase of E-AMDAR will last from 2013-2017. The Coordinating Member is the Met Office and the Programme Manager is Mr Steve Stringer. The Technical Co-ordinator is Mr Stewart Taylor.
