(updated on December 16, 2020) Within ALADIN and HIRLAM Consortia, the 3 CMCs (ALARO, AROME, HARMONIE-AROME) and the ALADIN configuration run operationally on a wide range of computers, from single workstations to vectorial computers in shared or distributed memory, and on a cluster of workstations under Linux. 53 operational configurations in short The table in the joint document summarizes the main data of the 53 main configurations operational in ALADIN/HIRLAM.

HARP Verification Toolbox

Patricia — 2015-05-11T18:11:31Z

HARP originally stands for the Hirlam-Aladin R Package for verification (although R package is extensively used in the HARP, the tool package is not limited to the R language and utilities). The main goal of the HARP development is to provide the HIRLAM-ALADIN community with suitable tools for probabilistic and mesoscale forecast verification, the latter with focus on spatial aspects. The plan for developing this joint package dates back to the ALADIN Workshop & HIRLAM All Staff (…) - Software and applications

Plots of experimental AROME 1.3 km

Patricia — 2013-01-11T14:45:00Z

Some experimental AROME configurations were daily run at 1.3 km and 2.5km. This experimentation has been stopped and will be replaced by runs of AROME High-Resolution with assimilation. More details when these runs are available. About the former 1.3km and 2.5km experimental runs : They are initialized and coupled with operational AROME-France (2.5 km). Two different vertical discretization are being tested : L90BB (a simple extrapolation of the operational 60 levels discretization (…) - Software and applications

On March 27, 2012 (5860 days since its first pre-operational run; 5100 days since its first operational run), ALADIN-France completed its last operational run. Since that day, the ALADIN reference version at Meteo-France is the ALADIN-RÃ©union model, one of the 4 Overseas ALADIN models operational at MÃ©tÃ©o-France. Some general features of this last version of ALADIN-France : It was based on ALADIN cycle CY36T1 and was run on Meteo-France Nec-SX9 computer. The centre of the domain (…) - Software and applications

Phasing

Patricia — 2008-04-11T18:33:00Z

This important operation is completed twice a year to "phase" the ALADIN code with its "mother" code ARPEGE (see history of cycles and phasing team and some statistics on phasing effort). The ALADIN code is following the ARPEGE one in its permanent evolution (see history of ALADIN cycles). This is due mainly to the technical evolution of calculating machines (CDC, CRAY 2, CRAY C90, FUJITSU, NEC...) which imposes a new adaptation of the code to the new machine properties. The evolution of (…) - Software codes

The ALADIN System

Patricia — 2002-09-11T18:17:00Z

ALADIN was entirely built on the notion of compatibility with its Â« mother Â» system, IFS/ARPEGE. The latter, a joint development between the European Centre for Medium-Range Weather Forecasts ([ECMWF->http://www.ecmwf.int) and MÃ©tÃ©o-France , was only meant to consider global Numerical Weather Prediction applications ; hence the idea, for ALADIN, to complement the IFS/ARPEGE project with a limited area model (LAM) version, while keeping the differences between the two softwares as small (…) - Software codes

The ALADIN configurations Nine are currently fully validated (the number is likely to increase in the near future, given the momentum of the project) : e923 : the creation of the Â« geographical Â» conditions for any given geometry of the LAM, anywhere on the globe ; e927/ee927 : the creation of initial and/or lateral boundary conditions starting from an ARPEGE or an ALADIN file ; e701 : the optimal interpolation analysis module nick-named CANARI ; e001 : the model integration itself (…) - Software codes
