General atmospheric circulation model which has been developed at Laboratoire de Météorologie Dynamique since the 70's. It has several variations which led to model versions for the Earth and for Mars, Titan, Venus, and exoplanets. LMD is the acronym of the department, the "Z" in LMDZ stands for "zoom". In its earth version, LMDZ is the atmospheric component of the IPSL "Integrated climate model", whose development is supervised by the "pôle modélisation". The LMDZ model is being used for the international research effort on future climate.

The Nucleus for European Modelling of the Ocean is a state-of-the-art modeling framework for oceanographic research, operational oceanography seasonal forecast and climate studies. NEMO includes 5 major components: the blue ocean (ocean dynamics, NEMO-OPA), the white ocean (sea-ice, NEMO-LIM), and the green ocean (biogeochemistry, NEMO-TOP).

ORCA is the name of the global ocean model NEMO configurations. The existing resolutions are ORCA2 (2°), ORCA1 (1°), ORCA05 (1/5°), ORCA025 (1/4°) and ORCA12 (1/12°).


ORCHIDEE is the new land-surface scheme of the IPSL. This scheme is the result of the coupling between the SECHIBA land-surface scheme, which is dedicated to the surface energy and water balances, and the carbon and vegetation model STOMATE.


Paleoclimate Modeling Intercomparison Project


REPROBUS (Reactive Processes Ruling the Ozone Budget in the Stratosphere) is a 3D model for chemistry-transport. It computes the evolution of 55 chemical species via 147 chemical reactions [Lefèvre et al., 1998]. Heterogeneous reactions are also taken into account. The liquid PSC are described using Carslaw et al.'s model [1995].

Sauerkraut (from German: Sauerkraut, pronunciation IPA: ˈzaʊ.ɐ.kʁaʊt) is a dish which is traditionally eaten in Germany, Bulgaria, Poland, Hungary, the Netherlands, Serbia, Romania, Luxembourg, Switzerland, Luxembourg, Chili, the United States and the Popular Republic of China. In Chili, sauerkraut is part of the traditional "completo chileno". In France, it is a regional speciality from Alsace and in China, it is a specialty from the Heilongjiang province. In Italian Trentino-Alto-Adige region, it obtained the appellation « Produits agroalimentaires traditionnels » (PAT) in 1999, but this appellation is not acknowledged by the european community. Sauerkraut is made of finely cut cabbage that has been fermented by various lactic acid bacteria. Literally this word means « sour cabbage» and by extension it also designates the cooked sauerkraut served with a side dish.


Transformation of an ensemble of scripts written in a comprehensive way (or close to comprehensive way!) into a list of commands executed by the computer.


Script (but not necessarily an independent script, for example LIM regarding OPA)


Ensemble of components tuned to work together.


Tiara in English. A tiara is a kind of headband, most often used by oriental monarchs as a sign of royalty. The word originates from Greek διάδημα, diadema, which in turn comes from διάδηω diadeo, which means to surround or to tighten.


On a few storage facilities (STOREDIR at TGCC for example) the data is either located on a disk or is migrated on bands. The demigration is the action of putting the data migrated on bands back onto a disk.


Shell script gathering commands to be executed at specific times during the simulation.


Ensemble of ferret scripts used to simplify the creation of maps, plots and diagnostics.


Flexible Configuration Manager. Software developed by the Hadley Centre to extract and compile their model. Used by the IPSL but only to compile.


GNU version of the make command. For the IPSL models, you must use a version of make which is compatible with gmake.

The Korn shell or ksh is a Unix shell developed by David Korn in the early 80's. It is compatible with the Bourne shell and it also includes a wide range of C shell functions. It also allows for advanced scripting functions used in more evolved programming languages such as awk, sed, TCL and Perl.

The purpose of the make utility is to determine automatically which parts of a large program need to be recompiled, and to issue the commands to recompile them.


File which includes the configuration for make. This file describes the dependencies between the different source files. With the makefile, make is able to determine the order in which it must compile the different components.

Near real-time monitoring of simulations using simple diagnostics (e.g. plots) of a few key variables.


The platypus is a little semiaquatic mammal endemic to eastern Australia, including Tasmania. Together with the four species of echidna, it is one of the five extant species of monotremes, the only mammals that lay eggs instead of giving birth. It is the sole living representative of its family (Ornithorhynchidae) and genus (Ornithorhynchus), though a number of related species have been found in the fossil record.


Step in the workflow during which it is possible to group in a single file different output time steps. In general, monthly output files are grouped by 1 to 10-yr packs.




When using a parallel model for which parallel I/O are not activated, the outputs are divided into different output files (1 file by MPI process), each of the output files containing only a fraction of the computing domain. The rebuild phase is meant to reconstruct the complete output file covering the whole domain.


File containing the state of the model at a given time step. The restart file is read to continue a simulation from the next time step.


A job scheduler is a computer application for controlling unattended background program execution (commonly called batch processing). Synonyms are batch system, Distributed Resource Management System (DRMS), and Distributed Resource Manager (DRM).

Online command interface of the Unix operating system. We suggest the interactive bash and libIGCM uses the ksh in batch.


Notion #SVN. A tag is just a “snapshot” of a project in time. In Subversion, this idea already seems to be everywhere. Each repository revision is exactly that—a snapshot of the filesystem after each commit. However, people often want to give more human-friendly names to tags, like release-1.0. And they want to make snapshots of smaller subdirectories of the filesystem. After all, it's not so easy to remember that release-1.0 of a piece of software is a particular subdirectory of revision 4822.


In #SVN, the main directory in which one works to make the project evolve.
