Observation du nuage du volcan islandais Eyjafjöll par les chercheurs d’ICARE Observation of Iceland’s Eyjafjallajökull Volcano ash plume by ICARE research scientists April 2010

Observation à l’IPSL / Observation at IPSL L’éruption du volcan islandais qui a cloué au sol l’aviation européenne a été observée par les moyens d’observations sol et aéroportés disponibles à l’Institut Pierre-Simon Laplace. Les chercheurs du LATMOS (CNRS/UPMC/UVSQ), du LMD (CNRS/UPMC/ENS/Ecole polytechnique) et du SIRTA ont analysé les observations récentes pour apporter des informations combinées sur l’évolution du panache de cendres consécutif à l’éruption, afin d’étudier sa distribution spatiale (à l’aide d’observation satellites) et de surveiller à quelle altitude les particules se déplacent (à l’aide de mesures sol et par satellite).
Ground-based and airborne instruments at the Institut Pierre-Simon Laplace provided observations of the eruption of the Iceland volcano, which grounded airplanes in Europe. Research scientists from LATMOS (CNRS/UPMC/UVSQ), LMD (CNRS/UPMC/ENS/Ecole polytechnique) and SIRTA laboratories have analyzed recent observations to document the ash plume development after the eruption. They study its spatial distribution (using satellite observations) and monitor the transport altitude of the particles (using ground-based and satellite observations).
