Sparse Days Meeting 2010

Sparse Days Meeting 2010 at CERFACS
June 15th-17th,  2010

 

The Sparse Days this year will be combined with the final meeting of the ANR Solstice Programme. The main themes for this project were: direct methods, hybrid methods, partitioning and ordering, and web access to codes and matrices (GRID-TLSE). Thus we will make these the very non-restrictive theme for our 2010 Sparse Days meeting. The meeting will start on the morning of Tuesday June 15th and finish around midday on Thursday June 17th; the exact schedule will depend on the papers accepted for presentation.

New regional climate projections for metropolitan France

superadmin |  11 February 2021

Cerfacs collaborated with Météo France and the Institut Pierre-Simon-Laplace (IPSL) to produce the DRIAS climate dataset, which presents a wide range of possible climate changes for metropolitan France for three periods of the 21st century (2021-2050, 2041-2070 and 2071-2100) and three greenhouse gas emission scenarios.

New research group “Theory and Climate”

Mélanie ROCHOUX |  1 February 2021

CECI is involved in the development of a new research group (GDR for “Groupement De Recherche”) entitled “Theory and Climate”. This GDR aims at bringing together the entire community of theorists (mathematicians, physicists, computer scientists, data scientists, etc.) working on climate sciences, with the goal of developing and sharing innovative concepts and tools relevant for a better understanding of climate dynamics. This GDR is interdisciplinary and involves several CNRS research institutes as well as most of French organizations working in these fields. CECI plans to contribute to issues related to climate dynamics and applied mathematics such as data assimilation and machine learning. Moreover, there are strong links between this GDR and the LEFE-INSU actions, in which CECI researchers are active (LEFE-IMAGO and LEFE-MANU actions). More information here:Read more
