The aim of the work is to design and develop light (less then 20 gr), expendable radioprobes to study complex micro-physical and chemical processes inside warm clouds. This includes the tracking of turbulent, both saturated and unsaturated, air parcels. With this new kind of radiosonde, we thus aim to obtain Lagrangian statistics of the intense turbulence inside warm clouds and of the lower intensity turbulence typical of the air surrounding them. The radiosonde is made of the radioprobe (the electronic board) attached to a biodegradable balloon filled with a mixture of helium and air. The system is able to float inside/into clouds for a time span of the order of a few hours and measure fluctuations of air temperature, pressure, humidity position, velocity and acceleration along with its own trajectory which... Preliminary in-field experiments were carried out with a single and multiple radiosondes in different environments. Sensor readings are validated by comparison with reference values provided by INRIM traceable instrumentation and/or ARPA (Piemonte) and OAvdA nearby meteorological stations. The last two experiments, INRIM, September 29, 2021 and OAVdA, February 10, 2022, addressed the possibility to implement a distance neighbor graph algorithm (Richardson LF - 1926) conceived for turbulent dispersion analysis in the atmosphere and which, actually, has not been yet realized in the context of in-field atmospheric observations.

用于环境观测的多参数微型无线电探空仪的验证和可追溯性

这项工作的目的是设计和开发轻型(小于 20 克)一次性放射性探测器,以研究暖云内复杂的微观物理和化学过程。这包括跟踪饱和和非饱和的湍流空气包裹。因此,使用这种新型无线电探空仪,我们的目标是获得暖云内部强烈湍流和周围空气典型的低强度湍流的拉格朗日统计数据。无线电探空仪由连接到充满氦气和空气混合物的可生物降解气球的无线电探头(电子板)制成。该系统能够在几个小时的时间跨度内漂浮/进入云层,并测量空气温度、压力、湿度位置、速度和加速度的波动以及它自己的轨迹…… 在不同环境中使用单个和多个无线电探空仪进行了初步的现场实验。传感器读数通过与 INRIM 可追溯仪器和/或 ARPA(皮埃蒙特)和 OAvdA 附近气象站提供的参考值进行比较来验证。最后两个实验,2021 年 9 月 29 日的 INRIM 和 2022 年 2 月 10 日的 OAVdA,解决了实施距离邻域图算法(Richardson LF - 1926)的可能性,该算法是为大气中的湍流扩散分析而构想的,实际上,它还没有在现场大气观测的背景下尚未实现。传感器读数通过与 INRIM 可追溯仪器和/或 ARPA(皮埃蒙特)和 OAvdA 附近气象站提供的参考值进行比较来验证。最后两个实验,2021 年 9 月 29 日的 INRIM 和 2022 年 2 月 10 日的 OAVdA,解决了实施距离邻域图算法(Richardson LF - 1926)的可能性,该算法是为大气中的湍流扩散分析而构想的,实际上,它还没有在现场大气观测的背景下尚未实现。传感器读数通过与 INRIM 可追溯仪器和/或 ARPA(皮埃蒙特)和 OAvdA 附近气象站提供的参考值进行比较来验证。最后两个实验,2021 年 9 月 29 日的 INRIM 和 2022 年 2 月 10 日的 OAVdA,解决了实施距离邻域图算法(Richardson LF - 1926)的可能性,该算法是为大气中的湍流扩散分析而构想的,实际上,它还没有在现场大气观测的背景下尚未实现。
