The list of major RC LACE events

* part of the text has been taken from "ALADIN history" document.

1990 : Meteorologist from Central Europe gathered at Vienna with the initiative to join the force toward the high resolution numerical modelling centre for Central Europe, Europe has just started to break the walls between East and West Europe. Within one-year time six meteorological services from Austria, Croatia, Czech Republic, Hungary, Slovakia and Slovenia established LACE initiative (Limited Area modelling for Central Europe), a core that should ensure the environment for the education, development and operative use of LAM in Central Europe.
November 1990: Meteo-France offers the NMSs of Bulgaria, the Czech Republic, Hungary, Poland, Romania and Slovakia jointly to develop and maintain a Limited Area version of the ARPEGE model with a view to a mutually beneficial collaboration in Numerical Weather Prediction (NWP) and meso-scale modelling.
Spring 1991: As one of the first decisions, LACE has evaluated the proposal that come from NWP group of Meteo-France and has proclaimed the interest to introduce LAM ALADIN as the model for the future operative application.
November 1994: The official cooperation between LACE and Meteo-France was signed.

Start of common LACE operations

Spring 1996: RC LACE Management group was established with the task to build the first operational ALADIN/LACE application and ensure the daily dissemination of NWP products to LACE members.
March-August 1996: In a form of cascade, the four applications start their cycle of pre-operational to operational status : ALADIN-MAROC and ALADIN-FRANCE (in March), ALADIN-LACE in Toulouse (in July), ALADIN-ROMANIA (in August).
July 1996: ALADIN/LACE has stated operative runs for +48h integration time at Meteo-France. ALADIN products for Central Europe domain has been disseminated via IBM Global Network link to ZAMG, Wienna, where data have been retransmitted to other LACE members (Bratislava, Budapest, Ljubljana, Prague, Zagreb)
February 1997: A quasi-operational status is given to ALADIN/SLOVENIA model.
February-March 1998: The workstation version ALADIN/HUNGARY is put into quasi-operational regime.

Start of Regional Center LACE

March 1998: First RC LACE MoU has been signed between: Austria, Czech Republic, Croatia, Hungary, Slovakia and Slovenia that defined the LACE Regional Center for operational LAM at CHMI,Prague and Telecommunication and Archiving center at ZAMG, Vienna.
June 1998: ALADIN-LACE quits Toulouse and starts its new life at LACE Regional Center, CHMI, Prague at NEC SX4/3A machine.
June 1998: ALADIN-FRANCE moves to the Fujitsu VPP and became fully operational.
September 1998: ALADIN /LACE operative product has increase resolution, from 14.75 to 12.17 km horizontally and from 27 to 31 levels in the vertical.
Last quarter of 1998: The workstation versions of ALADIN/AUSTRIA, and ALADIN/SLOVAKIA were put in pre-operational mode.
Summer 1999: First set-up of ALADIN/ 3D Var has been tested.
Autumn 1999: RC LACE became the back-up center for Global model ARPEGE products.
September-November 1999: LACE operative model is one of the official models at Meso-scale Alpine Programme Intensive Operative period (MAP IOP).
May 2000: ALATNET training network project started. Partners from France, Belgium and tree LACE members: Czech Republic, Hungary and Slovenia have hosted ALADIN research and training actions in period 2000-2004.
September 2000: First RC LACE MoU has been extended till 31st December 2002
October 2000: ALADIN-CROATIA reaches a pre-operational status.
June 2001: ALADIN/LACE initial conditions are computed using the blending technique instead of a pure dynamical adaptation method. Blending 6-hour assimilation cycle is operational at RC LACE Prague, and under tests at RMI Brussels and MF, Toulouse.
Autumn 2002: New official ALADIN-NH code has been developed by team work from Toulouse, Prague and Bratislava. ALADIN-NH is based on ICI scheme with new choices of prognostic variables. ALADIN-NH has been tested as the dynamic core for meso-gama model AROME.
October 2002: Second RC LACE MoU has been signed (duration till the end 2005). Members are oriented to own operational ALADIN applications, Project dedicated to Regional Co-operation LACE (RC LACE).

Start of decentralized organization


1 January, 2003: Start of new organisation of LACE with decentralised operations and increased level of scientific coordination (based on three working groups: dynamics and coupling, physics and data assimilation).
11-12 April, 2003: ALADIN-2 is born during scientific and political meeting organised in Prague.
May, 2003: Meteo-France is disseminating LACE LBC data via RETIM2000 satellite broadcasting, fully operational at the end of 2003.
January 2004: LACE enlarged the partnership with Meteo-France and officially joined the ALADIN-2 Project (meso-scale NWP research project, aim to develop the chain of NWP models from 10 to 2.5 km mesh size) as the first group from ALADIN community.
29-30 October, 2004: Discussions on the roadmap of the ALADIN-2 and AROME projects during the ALADIN Assembly in Split. Historical resolution for answering to the HIRLAM approach on the possible code collaboration between ALADIN and HIRLAM projects.
Winter 2004: ALADIN common verification server pre-operative status. Client-server application for synoptic scale verification has been tested at ARSO, Ljubljana.
May 2005: First operative ALADIN/ 3D Var has been launched at HMS, Budapest.Assimilation cycle is based on SYNOP, TEMP, ATOVS/AMSU-A satellite data observations.
October 2005: Second RC LACE MoU has been updated (duration till the end 2007). Members enlarged the activities and established the working groups for: Physic, Dynamic and Coupling, Data Assimilation and Predictability.
October 2005: Members of ALADIN Partners decided to sign new ALADIN MoU.
December 2005: ALADIN and HIRLAM signed the cooperation agreement. LACE Steering Committee has opened the meetings for the ALADIN and HIRLAM observers.
