Time series of the data used in this study. This data set is composed of (a) solar wind magnetic field, B, as input for the method HVG, (b) solar wind proton bulk speed, v_p, and (c) sunspot number, S_n, as variables for comparison. The first two data sets were obtained from NASA CDAweb by Wind Mission, while the last data set was obtained from World Data Center SILSO by the Royal Observatory of Belgium. The data shown correspond to measurements taken from 1 Jan. 1995 to 31 Dec. 2019, covering solar cycles 23 and 24. B, v_p, S_n time resolutions are 1 h, 92 s, and 1 day, respectively.
