SWICS abundances normalized to their photospheric values in (a) fast and (b) slow wind as a function of time, aggregated in 250-day intervals. The right axes plots the normalized 13-month smoothed sunspot number. The SWE abundances normalized to its photospheric values are plotted for reference. The vertical dotted lines indicate solar minimum 24. The vertical dash-dotted line indicates the helium shutoff (Alterman et al. 2021).
