Expert Team on Meteorological Services To ATM (MSTA) and Meteorological Information Exchange (ET-M&M)
Objectives

Identification and proposal of candidate MET Services To ATM (MSTA) grounded on an innovative and high-level scientific basis, in response to user needs and in coordination with the ICAO Meteorological Aeronautical Requirements and Information Exchange Project Team (MARIE-PT).

Proposal(s) for MSTA put forward to conjoint WMO/ICAO Meeting in 2014, supported by ICAO and the different user communities.

Provision of MSTA related MET Information Exchange needs to the CBS Task Team on Aviation XML.

Background

With increasing air traffic in several regions leading to severe issues of aerodrome and route capacity limits, different regions are developing different tailored meteorological product to support Air Traffic Management (ATM) to fill the perceived gap between the legacy products required by Annex 3 and ATM requirements on MET. In particular, the problem of significant convection impacting approach areas, corner points and fixes, which is already bringing significant impact to ATM operations, is not currently addressed by any regulated ICAO products.

To avoid further costly parallel development of similar products, with a high risk of confusion between similar products using different ways of textual or graphical presentation to users, the 13th Session of the WMO Commission of Aeronautical Meteorology (CAeM) held in Geneva in November 2006 decided to form a dedicated Expert Team on New Terminal Forecast (ET/NTF) with the task to develop, harmonize, and promote a prototype of a forecast for the wider terminal area intended mainly for ATM/ATC and operations staff.

Subsequently at the 14th Session of CAeM held in Hong Kong, China in February 2010 a new Expert Team on Meteorological Services for the Terminal Area (ET/MSTA) and a Task Team on MSTA User Needs (TT/MSTA-UN) were established to build on the work previously undertaken by the ET/NTF.

During the CAeM Management Group meeting in October 2011, in response to the establishment of the ICAO MARIE-PT, it was decided to merge the ET-MSTA & TT/MSTA-UN into one team and to expand the scope of the work to be performed to all MET Services to ATM and to also include MET Information Exchange related activities, encompassing the work of the Focal Point on OPMET Data Exchange. Consequently it was agreed to change the name of the Expert Team into Expert Team on Meteorological Services to ATM & Met Information Exchange (ET/M&M). With the guarantee that users requirements be channelled through the ICAO MARIE-PT, the need for a "formal" co-chair of TT/MSTA-UN from IATA is now reduced, but close contact with this IATA representative being an invited expert in the group would serve as a "quick response" resource for the team when it came to interpretation of user requirements, development of validation methods etc.

Terms of Reference

  • To strengthen working relationships with the user community, esp. with representatives from user groups, via the ICAO MARIE-PT;

  • To analyse the user needs from an innovative and high-level scientific perspective and perform a gap analysis with current MET capabilities;

  • To collate examples of best practice of MET services to ATM from Members and to demonstrate them in the ICAO MARIE-PT;

  • Set up verification and validation measures, in line to ATM performance requirements delivered by the ICAO MARIE-PT

  • To elaborate and coordinate the development of proposals of new MET services to ATM, with scientific basis and supported by well communicated verification and validation, in response to requests from the ICAO MARIE-PT;

  • To investigate the role of the human forecaster in view of new MET services to ATM;

  • To propose draft MSTA proposals supported by ICAO and the user community, with a view to their adoption at the next WMO/ICAO conjoint meeting in 2014 and their eventual inclusion in relevant ICAO guidance material(s):

  • To assist the ICAO MARIE-PT in their deliverables;

  • To follow-up all Aviation XML (e.g. WXXM) related activities

  • To bring the CAeM needs, for example the MSTA related MET Information Exchange needs, into the work of the CBS Task Team on Aviation XML;
