Two ESA services for solar wind high speed stream forecasting, ESWF (see Figure 1) and STEREO+CH, are provided by the Expert Service Group on Heliospheric Weather (swe.uni-graz.at). Currently, the solar wind speed at 1AU is calculated by using an empirical relation between solar wind speed and coronal hole area (Vrsnak, Temmer, Veronig, 2007). Compression and rarefaction effects, coronal hole locations, etc. change that speed profile. Studies show clear relations between the rise/fall of the in-situ measurement solar wind high speed streams and the width of a coronal hole (see Garton et al., 2018). The Master student will develop codes to implement such information to the ESA service and to improve the forecasted solar wind speed profiles.
The project position duration is 12 months starting November 1, 2020. The financial support (stipend) covers 500€ per month.

The global aim of this BSc. or MSc. project is to help develop and consolidate orbital tomography and provide a basis whereby it could be even more generally applied. The BSc. or MSc. student will work with laboratory and/or synchrotron based UHV systems on collaborative projects with the theory group of Peter Puschnig (KFU) and Forschung Zentrum Jülich (GER) through the FWF-funded project concerned with the same topic. Specific projects, molecules and experimental techniques will be decided upon discussion with the candidate.
