Space weather Observations at L1 to Advance Readiness – 1 (SOLAR-1) Level 3 1-Minute Average Retrospective data from the SupraThermal Ion Sensor (STIS)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: June 09, 2026 at 07:35 PM | Dataset Last Updated: May 28, 2026 at 12:00 AM
This data collection consists of archived Space weather Observations at L1 to Advance Readiness – 1 (SOLAR-1) Level 3 1-Minute Average Retrospective SupraThermal Ion Sensor (STIS) data. 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 SOLAR-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. SOLAR-1 launched on September 24, 2025. Other products available are auxiliary files (orb-pr_solar1, sc-att_solar1); Space Weather Prediction Center (SWPC) Real-Time STIS products (stis-l0b-solar1, stis-l1a_solar1, stis-l1b_solar1, stis-l2_solar1, and stis-l3_solar1); and, National Centers for Environmental Data (NCEI) Retrospective Science STIS products (sci_stis-l1a_solar1, sci_stis-l1b_solar1, and sci_stis-l2_solar1).
