THESEO is supported by the European Commission - DG XII - Environment and Climate Programme
THESEO is an ambitious field programme of wide-ranging activities throughout the northern hemisphere with measurements being made by instruments on balloons, aircraft and the ground. Its primary goal is to improve our understanding of the processes underlying the observed mid-latitude trends. THESEO is supported through EC's Environnement and Climate Programme (12 projects in total) and by many national funding agencies.
