The study will use measurements from the 3 SWA sensors to undertake studies of the nature of the solar wind particle populations, their thermodynamic properties and variability. At first, the project will carry out case studies, determining the polytropic behavior of plasma species from the analysis of in-situ observations. Through the polytropic index we will characterize the dynamic mechanisms in specific solar wind structures. Moreover, statistical studies of the Solar Wind thermodynamic properties (polytropic behavior and its correlation with other plasma parameters) over the covered heliocentric distance will be supported from the available data. Those studies will reveal the evolution of the solar wind plasma within the inner heliosphere. The results will be compared with observations by various other missions (e..g, Wind, Helios, Parker Solar Probe).

该研究将使用3个SWA传感器的测量值对太阳风颗粒种群的性质，其热力学特性和可变性进行研究。首先，该项目将进行案例研究，从而确定血浆物种对原位观测的多蚀行为。通过多粒子指数，我们将表征特定太阳风结构中的动态机制。此外，从可用的数据中支持太阳风热力学特性（多蚀行为及其与其他等离子体参数的相关性）的统计研究。这些研究将揭示内层内太阳风血浆的演变。结果将与其他各种任务的观察结果进行比较（例如，风，Helios，Parker太阳探针）。
