Colloque "Solar Metrology, Needs and Methods"

Le CNES et le LATMOS ont organisé un colloque "Solar Metrology, Needs and Methods" (Métrologie solaire, besoins et méthodes) qui s'est tenu du 7 au 9 octobre 2014 à Paris.

Le but de ce colloque était de faire se rencontrer les scientifiques travaillant en physique, métrologie et modélisation du soleil pour confronter les observations disponibles des paramètres solaires (irradiance totale et spectrale, diamètre et forme du soleil, héliosismologie, ...) des missions spatiales existantes (PICARD, SOHO, SDO) aux besoins des modèles solaires.
