This data collection consists of archived Space Weather Follow On Lagrange 1 (SOL-1) Level 1a data from the SupraThermal Ion Sensor (STIS). The archival process includes daily files. The STIS instrument generates 1 file per day per level in the netCDF-4 format. These data are produced by the STIS instrument aboard the SOL-1 spacecraft. The SupraThermal Ion Sensor (STIS) is a solid-state spectrometer device that measures suprathermal ions and electrons across a broad range of energies. STIS provides real-time, continuous observations to ensure early warning of various space weather impacts. 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); STIS files (stis-l0b_sol1, stis-l1b_sol1, stis-l2_sol1, and stis-l3_sol1); and, National Centers for Environmental Data (NCEI) Retrospective Science products (sci_stis-l1a_sol1, sci_stis-l1b_sol1, sci_stis-l2_sol1, and sci_stis-l3-avg1m-nt-bc_sol1).
