The workshop opened with a series of scene-setting talks that spanned a wide range of topics: from fundamental questions on cloud formation to challenges in modeling and satellite observation. The session on contrail avoidance as a potential climate mitigation strategy  sparked particularly lively discussion. With growing interest from the aviation industry in rerouting flights to avoid persistent contrails, participants debated whether current scientific understanding of cirrus clouds and their modeling is sufficient to support such measures. The consensus: not quite yet.

Of course, the workshop wasn’t all clouds and data. Evening gatherings and informal coffee break chats offered just as much inspiration and connection. Given the continued enthusiasm and engagement, we’re likely to be back with another edition in 2026!
