Solar wind speed map derived from Metis observations on June 21, 2020, with the coronal model assumptions of the T_e radial profile from Gibson et al. (1999), T_k = 1.0 MK, K_i = 1, and A_He = 10%. The lines overlaid on the image identify the angular sectors we defined to study the radial speed trends for different coronal structures. The regions between the red lines are associated with polar coronal holes, and those between the black lines correspond to equatorial regions.
