Softwares for data assimilation

FIREFLY

Ensemble Kalman Filter, implemented on a front propagation simulator and sequentially assimilating front positions observed for correct input parameters (surface winds, vegetal fuel) and state (position of the front) model.

DAMP

The DAMP platform (Data Assimilation with MASCARET) is dedicated to flood forecasting. It is based on solving equations river hydraulics (St. Venant equations) within the one-dimensional code MASCARET (developed by EDF and CEREMA). The implementation is done through dynamic coupling software OpenPALM that allows communication between the code and the calculation algorithm of the Kalman Filter assimilation by optimally managing  computing resources. Sequential assimilation of observed data in-situ water height corrects the errors on the friction coefficients,  hydrological and hydraulic inflow (height and flow rate) and thus improve the quality of short and medium forecast words (from several hours to 24 hours depending on the dynamics of watersheds). To date, DAMP is operationaly used at SPC at SAMA (Seine Marne Upstream Upstream) and is being implemented at a wider use SCHAPI to other basins.

Medal of the Academy of Air and Space: 3 CERFACS researchers awarded !

Brigitte Yzel |  11 July 2022

The Air and Space Academy awarded Carlos Pérez Arroyo, Gabriel Staffelbach and Jérôme Dombard with the Vermeil medal 2022, to honor the excellence of their work in the realization of the FULLEST project, the first high-fidelity simulation of an aircraft engine. Thanks to PRACE for awarding the access to the Joliot-Curie supercomputer (GENCI hosted at CEA/TGCC) and to DGAC for the funding of the ATOM project (No 2018-39) led by SAFRAN Tech. FULLEST also benefited from developments done in European projects:  EXCELLERAT (H2020 823691) and EPEEC (H2020 801051).  Read more
