This data collection consists of archived Space Weather Follow On Lagrange 1 (SOL-1) Level 1a data from the Solar Wind Plasma Sensor (SWiPS). The archival process includes daily files. The SWiPS instrument generates 1 file per day per level in the netCDF-4 format. These data are produced by the SWiPS instrument aboard the SOL-1 spacecraft. SWiPS monitors the solar wind for abrupt changes, which can result from interplanetary shocks, coronal mass ejections, corotating interaction regions or high speed solar wind, because these can cause geomagnetic storms that are harmful to life and technology. SOL-1 will launch in 2025. Other products available are auxiliary files (frm-rt-l0_sol1, frm-st-l0_sol1, pkt-l0_sol1, orb-pr_sol1, sc-att_sol1); SWiPS files (swips-l0b_sol1, swips-l1b_sol1, swips-l2_sol1, and swips-l3_sol1); and, National Centers for Environmental Data (NCEI) Retrospective Science products (sci_swips-l1a_sol1, sci_swips-l1b_sol1, and sci_swips-l2_sol1).
