Innovative, green, floating radiosondes to track small-scale fluctuations along isopycnic surfaces in and around warm clouds

Clouds are an important source of uncertainty in climate modelling and weather prediction models. Warm clouds have a cloud top that doesn’t contain any ice forms and are found to be responsible for 31% of the world’s rainfall. Hence, innovative, green, ultralight radiosondes are being conceived within the context of the H2020 MSCA ITN ClOud-MicroPhysics-turbuLEnce-Telemetry (COMPLETE) network, which aims to characterise the cloud boundary, and develop the current understanding of cloud physics and related turbulent dynamics. The radiosondes conceived within this network will contribute to the current understanding of microphysical processes in clouds in a range of a few 100m.
