Preliminary and definitive status are distinct. UTC dates denote scientific intervals, not historical publication times. SILSO SN excluded: CC BY-NC 4.0.

Historical dates may be approximate, uncertain, or BCE. Database records are scientific documentation, not current emergency warnings.

The GVP catalogue is a documented scientific database that changes as evidence is reviewed. It is not an official emergency-warning service.

Attribution: Smithsonian / USGS Weekly Volcanic Activity Report.

Weekly reports are selective, preliminary, subject to change, and not a comprehensive list of all eruptions or activity. This platform is not an official emergency-warning service.

Attribution: Ephemerides computed by NASA/JPL Horizons.

Ranges are apparent geocentric scientific ephemerides and are not a navigation product. Values may change when JPL updates ephemeris models or Earth-orientation predictions.

Native spacecraft epochs, not propagated Earth arrival times. Revisable archive; historical release and CDF version not reported by this HAPI response. Consult ACE instrument teams before publication.

Attribution: Space-weather event interpretations courtesy of NASA CCMC DONKI.

DONKI is a research and operational-support knowledge base. Associations are not proof of causality. This platform is not an official emergency-warning service.

Attribution: Natural-event metadata provided by NASA EONET.

NASA EONET is a curated near-real-time metadata source. EONET locations and extents are supplemental and may be approximate. They are not authoritative emergency boundaries. Follow relevant public authorities.

Solar-wind timestamps are bow-shock arrival intervals, not native L1 observations. OMNI is revisable; source IDs, propagation QA and exact raw evidence are retained. Historical release times are not supplied.

Attribution: Meteorological data provided by NASA POWER.

POWER values are gridded analysis-ready meteorological data, not local observations or operational warnings. This deployment stores configurable sample points, not every native grid cell.

Attribution: NASA/SPDF; Wind MFI and SWE instrument teams

Native spacecraft epochs and positions, not propagated Earth arrival times. SWE quality mode bits follow the updated NASA guide, not stale HAPI descriptions. Revisable archive; historical release time not supplied.

Attribution: NOAA/NWS Space Weather Prediction Center DSCOVR data, archived by NOAA/NESDIS National Centers for Environmental Information.

SPOT inventory entries describe remote daily gzip occurrences. Publication requires a locally verified canonical NetCDF object; only the explicit seven-variable profile is normalized and every native variable remains inventoried.

Attribution: NOAA/NESDIS National Centers for Environmental Information GOES data.

Catalogue entries identify remote NetCDF assets. They are not normalized measurements and do not imply that the object bytes are locally realized. Science-quality and operational products remain distinct.

Files are revised by NCEI; recent years can be incomplete and prior years can receive corrections. Preserve creation date and raw file identity.

Post-storm best-track analysis is not a forecast. Completeness and accuracy vary by basin and historical era; missing values remain explicit.

Attribution: NOAA/NESDIS SOLAR-1 instrument teams; NOAA SWPC and NCEI.

Native SOLAR-1 times are not Earth-arrival times. RTSW is operational quality and covers a rolling 24 hours. CCOR-2 references do not imply local image bytes or verified remote SHA-256/version IDs. No historical publication times are invented.

Verification-oriented data can be incomplete or revised; tornadoes were likely underreported before 1953, hail criteria changed in 2010, and monetary-loss values are highly suspect.

Current, estimated, and forecast products retain their NOAA labels. This platform is not an official emergency-warning service; consult NOAA SWPC and relevant authorities.

Preliminary operational reports may be revised; not final research data. Native four-digit region labels are not globally unique. Part II is expected return, not a current observation. Not SILSO sunspot number. No NOAA endorsement; derived tables are not official government products.

USGS information is preliminary and subject to revision. This platform is not an official emergency-warning service; follow relevant public authorities.

Attribution: U.S. Geological Survey, 2020, doi:10.5066/P9BCVRCK; retain native feature cooperators.

Static interpreted surface traces, not deterministic earthquake prediction or fault probability. Native classes and review dates retained; HTTP Last-Modified is not a geological observation date.
