ZCB 2026-09-25T11:01:21 Added publication info in order to create DOI. TLK This set of IMP 6 LANL 1-hr solar wind plasma parameter data includes temperature anisotropy and alpha/proton ratio. This hourly resolution data set was created at NSSDC in the year 2003 by averaging 2-min resolution solar wind data provided over the years by LANL. Magnetosheath data were excluded from the 2-min data by LANL. This data set supersedes hourly solar wind data provided by LANL over the years.
