| Popis: | A new way of tracking air fluctuations inside warm clouds has been proposed as part of the Horizon 2020 Innovative Training Network ClOud-MicroPhysics-turbuLEnce- TElemetry project. Part of the project aims to design a new kind of ultralight radio probe capable of floating in clouds. This paper describes a method of balloon radiosonde trajectory reconstruction for warm clouds investigation. Each balloon radiosonde contains a set of four accelerometers in which one of the accelerometers is located at the center of gravity of the system. The rotation rates of the balloon radiosonde can be calculated via the output differences between the centered accelerometer and the other three. By applying the rotation matrices and the integration, the position of the balloon radiosondes over time can be determined. Low-pass filters are also applied to the output of accelerometers in order to reduce the impact of noise. |
