The clouds' contribute to environmental system is enormous; clouds can produce solid and liquid water though a series of physical phenomena that take place at different spacial scales. The presence or absence of clouds is essential for many weather aspects. The understanding of both the chemistry and physics of clouds can lead to a wider knowledge of the chemistry and physics of real-world phenomena. Clouds' processes take place at different spacial scales, the phenomena that occur at the micro scale are non generally visible to human eye. Humans see the macroscopic scales, the net consequence of the light, coming from the sun, scattered by the presence of water drops and small ice crystals inside clouds. In particular warm clouds can contain thousands of different sizes of droplets, but every raindrop that fall to the ground is the result of million clouds' droplets that has gathered together. The uncertainties related to the processes that involve the formation, the structure and the life of clouds are still nowadays subject of studies and researches. The COMPLETE project, a Horizon2020 program, has the aim to widen current knowledge about those processes and phenomena inside clouds that involve non linear and turbulent flows. The experimental part of this project aims to follow the motion of particles inside clouds in a Lagrangian way thanks to the use of mini probes that can measure proprieties as temperature, pressure, humidity, velocity and trajectory and then send these data to a ground receiver. Those probes are able to fluctuate thanks to biodegradable balloons that float along whit the main stream. In this thesis will be illustrated the current state of knowledge about these arguments and then will be presented the structure and architecture of the probe developed so far with some data measured during tests.
