HIGH DIELECTRONIC SATELLITE LINES IN SOLAR FLARE SPECTRA

Les raies de résonance des ions fortement ionisés des séries isoélectroniques de l'hydrogène et de l'hélium et les raies satellites associées sont utilisées pour déterminer la température électronique et l'évolution du plasma lors des éruptions solaires. Des calculs du rapport d'intensité des raies satellites 1s2nl-1s2pnl à la raie de résonance 1s2-1s2p ont été effectués pour les raies du Fe XXIV pour n = 2, 3, 4. Les résultats obtenus ont permis l'identification de nombreuses raies du seul spectre à haute résolution d'éruption solaire obtenu jusqu'ici par satellite et donnent une meilleure estimation de l'intensité de la raie de résonance en déterminant les contributions dues aux raies satellites correspondant à n ≥ 3.Resonance lines of highly ionized H and He-like ions and their associated satellite lines are used to determine the electron temperature and the transient state of the plasma in solar flares. The intensity ratio of the satellite lines 1s2nl-1s2pnl to the resonance line 1s2-1s2p has been calculated for the n = 2, 3 and 4 shells of Fe XXIV. The results have enabled the identification of many lines in the only available high resolution solar flare iron spectrum and give a good estimate of the spectral intensity in the resonance line by evaluating the contribution due to the blending of the satellites with n ≥ 3

Developing a Common Information Model for climate models and data

International audienceThe Metafor project, funded under the EU Framework Programme 7, proposes a Common Information Model (CIM) to describe in a standard way climate data and the models and modelling environments that produced this data. To establish the CIM, Metafor first considered the metadata models developed by other groups engaged in similar efforts in Europe and worlwide, such as the US Earth System Curator, explored fragmentation and gaps as well as duplication of information present in these metadata models, and reviewed current problems in identifying, accessing or using climate data present in existing repositories. Based on this analysis and on different use cases, the first version of the CIM is composed of 5 packages. The "data" package is used to describe the data objects that can be collected and stored in any number of ways; the "activity" package details the simulations and experiments and related requirements that were performed with numerical (possibly coupled) models described with the "software" packages. Both data and models can be associated with numerical grids represented by the "grid" package and finally the "shared" package gathers concepts shared among the other packages. The CIM is defined and implemented in the Unified Modelling Language (UML) and application schema have been generated in XML schema. Aiming at a wide adoption of the CIM, Metafor will optimize the way climate data infrastructures are used to store knowledge, thereby adding value to primary research data and information, and providing an essential asset for the numerous stakeholders actively engaged in climate change issues (policy, research, impacts, mitigation, private sector)

The PRISM software framework and the OASIS coupler

The increasing complexity of Earth system models (ESMs) and computing facilities puts a heavy technical burden on the research teams active in climate modelling. PRISM provides the Earth System Modelling community with a forum to promote sharing of development, maintenance and support of standards and software tools used to assemble, run, and analyse ESMs based on state-of-the-art component models (ocean, atmosphere, land surface, etc..) developed in the different climate research centres in Europe and elsewhere. PRISM is organised as a distributed network of experts who contribute to five "PRISM Areas of Expertise" (PAE): 1) Code coupling and I/O, 2) Integration and modelling environments, 3) Data processing, visualisation and management, 4) Meta-data, and 5) Computing. For example, the PAE “Code coupling and I/O” develops and supports the OASIS coupler, a software allowing synchronized exchanges of coupling information between numerical codes representing different components of the climate system. OASIS successfully demonstrates shared software, capitalising about 25 person-years of mutual developments and fulfilling the coupling needs of about 15 climate research groups around the world
