Abstract
The mini ultralight smart balloon is a strategic new kind of expendable low cost, small (max 30 cm),light (about 20 g), environmental friendly (Mater-Bi.) radio probe embedding a microprocessor,IMU, GPS and sensors for the measurement inside clouds of velocity, acceleration, pressure,temperature, humidity and aerosol concentration fluctuations. To be released with the help of UAVs(Unmanned Aerial Vehicles), our probes are designed to passively float inside clouds and are about20 and 100 times lighter than NCAR (National Centre for Atmospheric Research, US) drop-sondes(i.e. non-floating sondes) and NOAA (National Oceanic and Atmospheric Administration, US) smartballoons, respectively.Our radio-sonde is mini in size: thus, it can sense air - water vapor – water droplets –aerosolsphysical-chemical fluctuations down to a few centimeters for the wavelength and up to frequenciesof a few hertz. It is green: the balloon is biodegradable (Mater Bi, Novamont). It is expendable: weforesee a final cost of the order of 40 euros. It is easily manageable: it can be positioned in-situ bydrones and then released to freely float inside clouds or other atmospheric environments.Atmospheric radio-sondes currently in use are not able to passively float inside clouds. Thoseconceived for lapse rate sounding rise through the atmosphere while being convectively transportedby the local wind shear, if present. The drop-sonde fall under gravity across the Planetary BoundaryLayers. They are released by aircrafts and reach the Earth surface in a few minutes. NOAA LASB arelarge balloon (11-feet) sondes which are wind transported for a time lapse up to a few weeks andhundreds to thousand kilometres (for many degrees both in latitude and longitude). They areconceived to track large scale atmospheric Lagrangian motions inside the low Troposphere. Theadjective smart refers to the capability to adjust the altitude but not to the biodegradability of theballoon material. NOAA smart balloon send data via a transponder to a C130 research aircraft flyingin the vicinity of the balloon. They thus require aircraft support all along their flight trajectories.
Cloud-MicroPhysics-Turbulence-Telemetry: An inter-multidisciplinary training network for enhancing the understanding and modeling of atmospheric clouds, (2016-2020) - Responsabile Scientifico
UE-funded research - H2020 - Excellent Science - Marie Curie
Abstract
Clouds are the largest source of uncertainty in weather prediction, climate science, and remain a weak link in modelingatmospheric circulation. This is rooted in the fact that clouds depend on the physical and chemical processes over a hugerange of scales, from the collisions of micron-sized droplets and particles to the airflow dynamics on the scales of thousandsof meters. Since ambiguities related to representation of clouds in climate models prevail, explorative observations are stillneeded. The challenge is on the one hand to establish connections across this range of scales, from aerosol and particlemicrophysics to macro-scale turbulent dynamics in clouds, and on the other to combine knowledge and training across vastlydifferent scientific and engineering disciplines. The aim of COMPLETE is to develop an inter/multidisciplinary trainingnetwork that will prepare high-potential early stage researchers (ESRs) with both scientific and industrially-oriented skills thatwill advance our understanding in these multi-scale complex natural phenomena. COMPLETE will vastly improve Europe’sposition as a global leader in technology, science and innovation to address climate change challenges.
