Ulysses SWICS Solar Wind Moments of Main Heavy Ions 3.5 Hour Data

Published by NASA Space Physics Data Facility (SPDF) Data Services | National Aeronautics and Space Administration | Catalog Last Checked: June 23, 2026 at 09:06 PM | Dataset Last Updated: June 22, 2026
This ASCII data set consists of a table of 3.5-hour averages of velocities (km/s), temperatures (deg.-K), and density ratios (relative to oxygen 6+) of solar wind ion composition measurements by the Ulysses SWICS experiment for alphas, carbon 6+, oxygen 6+ (density ratio = unity), neon 8+, magnesium 10+, silicon 9+, sulfur 10+, and iron 11+. Data accumulation times for the averages ensure that percentage errors are less than twenty percent for the density ratios. Each ASCII data file contains one month of data. The experiment and data processing are further described in G. Gloeckler, et al., The Solar Wind Ion Composition Spectrometer, Astron. Astrophys., 92(2), 267-289, 1992.
