 The Newsletter No. 7 for an Happy Anniversary !

The 7th edition of the combined Newsletter of the HIRLAM and ALADIN consortia was published on September 1st, 2016. Besides some articles around the presentations/posters at the last Wk/ASM (April 4-8, 2016, Lisbon), a special focus is given on recent Doctors, on some articles recently published.
As the ALADIN adventure concretely began on September 1991, we take the opportunity of this anniversary to think back and share some ALADIN stories.

 Soon to come

The concept of the ALADIN project was proposed by Météo-France in 1990, with the aim of building a mutually beneficial collaboration with the National Meteorological Services of Central and Eastern Europe. This collaboration was to be in the field of Numerical Weather Prediction (NWP), which provides the basis for the forecasting tools of modern meteorology. The easy to translate acronym (Aire Limitée Adaptation dynamique Développement InterNational) clearly indicates the major axes of this project at its beginnings.

25 years later, as defined in the 5th Memorandum of Understanding,

The goal of the ALADIN Collaboration is to improve the value of the meteorological, hydrological and environmental warning and forecast services delivered by all Members to their users, through the operational implementation of a NWP system capable of resolving horizontal scales from the meso-beta to the meso-gamma scale and improving the prediction of severe weather phenomena such as heavy precipitation, intensive convection and strong winds.

This objective will be fulfilled through continuation and expansion of the activities of the ALADIN Consortium in the field of High Resolution Short Range Weather Forecast, including:

  • Maintenance of an ALADIN System (...);
  • Joint research and development activities, on the basis of the common Strategic Plan and related Work Plans, with the aim of maintaining the ALADIN System at scientific and technical state of the art level within the NWP community;
  • Sharing scientific results, numerical codes, operational environments, related expertise and know-how, as necessary for all ALADIN Consortium members to conduct operational and research activities with the same tools.

About one hundred scientists, from sixteen countries, each with its own specificity in resources and knowledge base, are permanently contributing to the progress of ALADIN NWP system. They are working together on a modern code of the atmosphere that definitely deserves its proper place between the European state-of-the-art NWP models: 80 Full-Time Equivalent persons in the last years of the project’s life. This code is now operated every day in fifteen Euro-Mediterranean countries, on a huge variety of computing platforms ranging from a PC Cluster under Linux to Vector Computers.

ALADIN consortium had a number of unique successes in the past : for instance, the plugging of an existing physics parameterization in the existing code, leading to the AROME model; ALADIN is at the forefront of the gray-zone problematics with the ALARO physics; ALADIN dynamical core is remarkably stable; ...

ALADIN also allowed to build a high-level scientific team, distributed in sixteen countries that managed to reach the level of the best research centres, as witnessed by the PhD theses and publications in international journals. The General Assembly of Partners, the workshops, the meetings, the newsletters regularly offer opportunity of various exchanges within the ALADIN community.

ALADIN is preparing for the serious evolutions expected within the NWP landscape in the coming five to ten years. There is the ever-lasting question where to draw the line between resolved vs. parameterized processes. There is the question of the efficiency and the scalability of ALADIN dynamical core. There are the external drivers, such as the demands of the end users, and the evolution of the high-performance computing machines. Additionally a serious reorganization of the code is now at hand, in particular within the OOPS project. Besides that, the international meteorological context is steadily changing, specifically with the merger of the ALADIN and the HIRLAM consortia.

History of the governance : 1991-2016
Article published on 21 July 2008
by Patricia by

The organisation of the ALADIN project changes according to the evolution of the project (see also the history of the project).

 1991 - 1995 : gestation

  • From September 1991 until end of 1995, the work on ALADIN centered around visits to Toulouse of scientists of all partners, their ALADIN-related work at home being mostly conditioned by the tasks they had been performing in Toulouse. The number of hours of work shared in Toulouse with colleagues of all origins allowed a homogeneous and united team to be formed.
  • The main difficulty of the set-up was the financing of the travel and visits. Generally speaking, travel was provided by the partners and the grants for the stays were funded by Météo-France or by French ministries or raised in competitive applications by either all partners or by Météo-France and one partner for bilateral support or directly financed by partners.

 1996 - 2001 : decentralization and formalization through the 1st MoU

  • With the transition to multiple operational status thanks to a "standard open" code, the situation changed. The manpower involved in the development of ALADIN has kept increasing and covers now not only centralized actions of research and source code maintenance in Toulouse but also deported work in NMS, related to the implementation of local versions of ALADIN, the exploitation of the model outputs, the verification of forecasts and local research developments.
  • The necessary formalization of the project before its decentralization was completed by the signing of a first Memorandum of Understanding by all partners. It layed down he principles observed by ALADIN since the beginning, the choice of software, conditions of its use by the partners and of membership of, admission to, and withdrawal from the ALADIN "club".
  • The 10-years ALADIN anniversary was celebrated in Paris on May 31st, 2001 and a booklet was printed.

 2001 - 2005 : 2nd MoU with enlarged definition of the ALADIN partnership, guidelines for the commercial use, creation of a Technical Cooperation Standing Committee

  • A second ALADIN Memorandum of Understanding was signed on May 31st 2001 with mainly:
    • an enlarged definition of the ALADIN partnership, with three levels of "rights versus duties" : Full Member, Associated Member, User;
    • more precise guidelines for the commercial use of ALADIN products;
    • stricter rules for the registration of the manpower dedicated to ALADIN;
    • creation of a Technical Cooperation Standing Committee (TCSC) of for members (Météo-France, a LACE representative, a SELAM representative, a representative of the other partners), in charge of the routine project coordination. This TCSC was replaced by a 6 permanent members working group "Science and Strategy Committee" during the Assembly in Casablanca (2002) : the purpose of this old SSI was to supervise priorities and co-operation with other SRNWP groups, to follow AROME project and to report to the Assembly on progress of the scientific plan.

 end of 2005 : the 3rd MoU defines the new organisation

  • the governance and the management are adapted: General Assembly (with its Chairperson and Vice-Chairperson), Program Manager, Policy Advisory Committee, ALADIN Local Teams Managers, Program Team, Committee for Scientific and System/maintenance Issues, System/maintenance and Scientific Coordinators, Support Team
  • the MoU defines more precisely the relationships between governing bodies with a proposed way of circulating information, request and decision between GA, PAC, PM and Directors on one hand, in consistency with HIRLAM and with ECMWF

 end of 2010 : the 4th MoU defines the organisation for 2011-2015

  • The evolution of the content from MoU3 is mainly a better balancing within the management entities (LTMs more active in planning and reporting, CSSI more involved in applications) and the harmonisation with HIRLAM, including the possibility to temporarily and jointly active “task-forces”.

 beginning of 2016 : the 5th MoU defines the current organisation

The differences from the 4th MoU concern :

  • the introduction of the notion of Canonical Model Configurations (i.e. AROME or ALARO)
  • the new half-time ALADIN funded position for a Code Architect
  • the increase of the flat-rate ceiling to take into account the CA funded position
  • some changes in the article 11 about "Ownership, avalability and use of ALADIN products". the ALADIN-HIRLAM cooperation agreement was removed from the MoU text and remains as a stand alone document that is to be renewed and signed with HIRLAM consortium.
