The #HALO Status Colloquium 2025 at the #Paulinum in #Leipzig started today with the welcome by Eva Inés Obergfell (Rector of @unileipzig), a summary by coordinator Manfred Wendisch and talks by Andreas Engel & Joachim Curtius (both: @goetheuni) about HALO missions #ASCCI in #Arctic & #CAFEPacific in #Australia. And impressive numbers: up to 500 flight hours & 32 publications per year! Until Friday, they will discuss current results and prepare next missions, such as #HALOSouth. @dfg_public
