This presentation highlights the collaborative efforts between the German Meteorological Service (DWD) and the Karlsruhe Institute of Technology (KIT) in the field of satellite-based cloud research. We begin with a brief overview of the generation and utilization of satellite products at DWD (specifically within the satellite based climate monitoring (KU43) unit) and KIT, showcasing recent advancements and key developments at both institutions.

A particular focus is on the satellite-based analysis of fog and low clouds. KIT has developed innovative methods for detecting and characterizing these phenomena over Europe and Namibia, which are currently being implemented by DWD within the operational CLAAS-4 satellite data processing framework. The presentation concludes with insights gained from these products, shedding light on fog dynamics and their implications for weather forecasting and climate monitoring.
