Abstract: The solar wind is a nearly collisionless plasma that exhibits turbulent dynamics at several heliospheric distances. Although the turbulent nature of the solar wind has been studied for decades using in-situ and remote-sensing measurements from a fleet of spacecraft missions, it is still unclear whether there is a simple and direct connection between the turbulence properties measured in a plasma parcel and its source region in the Solar surface. Moreover, it is still uncertain whether the source region or the radial evolution is the more relevant parameter to define the state and type of turbulence of a plasma parcel at a given heliospheric distance, or if it is a more complex combination of both. To tackle these questions, we focus on two types of source regions, namely Coronal Holes and Active Regions. Using data from the European Space Agency mission Solar Orbiter we build a catalogue of possible connection events between the source regions and plasma parcels. We combine the well-established connectivity tool (IRAP) and set data thresholds on composition and plasma measurements from the Heavy Ion Sensor and Proton Alpha Sensor of the Solar Wind Analyser suit on board Solar Orbiter. With this catalogue, we explore and characterise differences in the energy containing scale and energy cascade rates for the two types of source regions as a function of heliospheric distance.
