The NSSDC Coordinated Heliospheric Observations Web, COHOWeb, hourly and daily Solar-Terrestrial Relations Observatory-A, STEREO-B, data were made by using high resolution data from from CDAWeb. The STEREO-A COHO file include data derived from the STEREO-A In-Situ Measurements of Particles and CME Transients, IMPACT, Fluxgate Magnetometer data, Thermal Plasma Moments: Solar Wind Proton and Ion Densities, Speeds, Velocity Vector Flow Angles, and Temperatures from the STEREO-A Plasma and Supra-Thermal Ion Composition, PLASTIC, Instrument, and Energetic Particle Fluxes from the STEREO-A IMPACT Solar Energetic Particle, SEP, Instrument Suite including the Low Energy Telescope, LET, High Energy Telescope, HET, and Suprathermal Ion Telescope, SIT. COHOWeb's magnetic field hourly averages were created at GSFC/SPDF by averaging over the six 10-min averages falling within each hour. Hourly plasma parameter data were obtained from UNH via http://fiji.sr.unh.edu/1dmax_ascii/.

Hourly Averaged Definitive Multispacecraft Interplanetary ParametersData. The Heliographic Inertial, HGI, Coordinates are Sun-Centered and inertially fixed with respect to an X-Axis directed along the Intersection Line of the Ecliptic and Solar Equatorial Planes. The Solar Equatorial Plane is inclined at 7.25° from the Ecliptic. This Direction was towards Ecliptic Longitude of 74.367° on 1 January 1900 at 1200 UT but because of Precession of the Celestial Equator, this Longitude increases by 1.4° per Century. The Z-Axis is directed Perpendicular and Northward from the Solar Equator, and the Y-Axis completes the Right-Handed Set. This System differs from usual Heliographic Coordinates, e.g. Carrington Longitudes, which are fixed in the Frame of the Rotating Sun. The RTN System is fixed at a Spacecraft or a Planet. The R-Axis is directed radially away from the Sun, the T-Axis is the Cross Product of the Solar Rotation Axis and the R-Axis, and the N-Axis is the Cross Product of the R-Axis and T-Axis. At 0° Heliographic Latitude when the Spacecraft is in the Solar Equatorial Plane, the N-Axis and Solar Rotation Axis are Parallel. Latitude and Longitude Angles of Solar Wind Plasma Flow are generally measured from the Radius Vector away from the Sun. In all cases, Latitude Angles are Positive for North-Going Flow. The Flow Longitude Angles have been treated differently for the Near-Earth Data, i.e. the OMNI, and for the Deep Space Data. The Flow is Positive for the Near-Earth Data when coming from the Right Side of the Sun as viewed from the Earth, i.e. flowing toward +Y from -X GSE or Opposite to the Direction of Planetary Motion. On the other hand, the Flow Longitudes for the Deep Space Spacecraft use the opposite Sign Convection, i.e. Positive for Flow in the +T Direction in the RTN System.

The data include 30-second proton speed, density, most probable thermal speed, and arrival direction, as well as predicted alpha-particle speed. Also included are the SOHO spacecraft predicted positon in GSE coordinates, Heliocentric Range, Heliographic Latitude and Longitude, and Earth Carrington Rotation Number.

This data collection consists of archived Space Weather Follow On (SWFO) Level 0a data from the Compact Coronagraph-1 (CCOR1) on Geostationary Operational Environmental Satellite 19 (GOES-19). The archival process includes daily files. The CCOR-1 instrument generates 96 files per day per level in one tar file that contains FITS. These data are produced by the CCOR-1 instrument aboard the GOES-19 spacecraft. The instrument observes broadband optical light that is scattered of coronal electrons and heliospheric dust. GOES-19 launched in late April 2024. Other products available are auxiliary files (pkt-l0_g19, orb-pr_g19, and sc-att_g19); CCOR1 files (ccor1-l0b_g19, ccor1-l1a_g19, ccor1-l1b_g19, ccor1-l2_g19, and ccor1-l3_g19); and, National Centers for Environmental Data (NCEI) Retrospective Science products (sci_ccor1-l1a_g19, sci_ccor1-l1b_g19, sci_ccor1-l2_g19, and sci_ccor1-l3_g19).

Data quality notice: The SAGE III/ISS team recommends against using data from events 2024030913SS, 2024030915SS, and 2024030917SS. These events were affected by line-of-sight blockage from a docked spacecraft which undermined the data quality. Typically, such events are withheld by a quality assurance process. g3bt_53 is the Stratospheric Aerosol and Gas Experiment III (SAGE III) on the International Space Station (ISS) (SAGE III/ISS) Level 1B Solar Event Transmission Data (HDF5) V053 data product. It contains pixel group transmission profiles for a single solar event. Launched on February 19, 2017 on a SpaceX Falcon 9 from Kennedy Space Center, the Stratospheric Aerosol and Gas Experiment III on the International Space Station (SAGE III/ISS), the second instrument from the SAGE III project, is externally mounted on the International Space Station (ISS). This ISS-based instrument uses a technique known as occultation, which involves looking at the light from the Sun or Moon as it passes through Earth’s atmosphere at the edge, or limb, of the planet to provide long-term monitoring of ozone vertical profiles of the stratosphere and mesosphere. The data provided by SAGE III/ISS includes other key components of atmospheric composition and their long-term variability, focusing on the study of aerosols, nitrogen dioxide, nitrogen trioxide, and water vapor. SAGE data has historically been used by the World Meteorological Organization to inform their periodic assessments of ozone depletion. These new observations from the International Space Station will continue the SAGE team's contributions to ongoing scientific understanding of the Earth's atmosphere.

The data include 5-minute proton speed, density, most probable thermal speed, and arrival direction, as well as predicted alpha-particle speed.
