Description: Main Objective: The target of this study is the observation of small-scale structures with a full coverage by photospheric, chromospheric and coronal instruments. Scientific Justification: The key idea of this proposal is to improve the understanding of small-scale structures, which cause upflows in the solar corona. They are seen as small blue-shifts in Hinode/EIS data and show only small brightenings or faint eruptions in imaging data. The additional use of the ground-based GREGOR telescope will provide full coverage of those coronal features down till the photosphere. This could help to detect potential underlying mechanisms and their behaviour through different depths for individual events. The relevance of small features increased strongly after the discovery of campfires in Solar Orbiter EUI data and small fluctuations in the solar wind detected by Parker Solar Probe. This study will help to prepare for prospective combined observing missions with Solar Orbiter.
