 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.

Graphics of the participation in the ALADIN project, figures as on 30 June 2015

Statistics about the manpower involved in ALADIN are regularly produced thanks to the ALADIN work accounting realized by the LTM (ALADIN correspondents) following the rules defined in the MoU.

The statistics below were prepared at the end of MoU4, for the 20th General Assembly and the MoU5 signature.

 Breakdown of the manpower at the end of June 2015 and during Mo4

All Partners significantly contributed to the manpower, even if the accumulated data since 1991 may give a distorted view for the last countries to join ALADIN.

 Manpower changes during time

The accumulated manpower investment since the start of ALADIN in 1991 is equivalent to 51.4 FTE (about 89 FTE during MoU4 years), with more work being done by "key" persons, working mostly full-time on ALADIN

 Mobility

82% of the total manpower invested in ALADIN since 1991 was realized by permanent staffs in their NMSs, the mobility showing a long-term decrease (with more increased possibilities for virtual mobility, through tele- web- or video- conferencing).
Whereas historically strong exchanges within LACE contries or on a bilateral basis between some flat-rate Partners and Meteo-France exist, the flat-rate mechanism does facilitate the scientific visits involving flat-rate Partners

 Manpower evolution of Partners or Components of the consortia

Since 1991, the manpower was done at 36% by LACE, 35% by Meteo-France and 29% by the flat-rate Partners, with differences in this breakdown according to the MoUs periods. The investment by each Partner is also changing depending on the evolution of the local staffs dedicated to ALADIN

 Type of work at the end of June 2015

Since July 2001, the ALADIN effort is split in 3 categories (direct work, maintenance of local applications, development of interfaces to other applications). The type of work is also characterized (training, tuition, networking,maintenance, validation, development, operational). Since January 2007, the manpower is also split in "in-kind" or "not in-kind" work. Since January 2012, the manpower invested has been scrutinized through additional criteria (code design and parallelization).
