Le parc instrumental de la plateforme mobile PEGASUS est dédié à la caractérisation de la composition atmosphérique (aérosols et gaz trace), et en particulier à l’étude des propriétés des aérosols atmosphériques qui en conditionnent les effets direct et indirect sur le bilan de rayonnement. PEGASUS est ainsi équipée d’instruments qui lui sont propres et qui sont systématiquement mis en œuvre lors d’une campagne (instrumentation de base), ainsi que de l’instrumentation de l’équipe MEREIA et plus généralement du LISA qui sont mis à disposition selon l’objectif scientifique de la campagne (instrumentation optionnelle).
