PRISM provides weather datasets such as daily precipitation, temperature, drought indicators, and solar irradiance.
GOES Space Environment Monitor
NOAA's GOES 1–15 instruments measured particles, magnetic fields, and solar irradiance and captured images of the Sun.

About GOES Space Environment Monitor
The GOES 1–15 Space Weather Instruments page from NOAA NCEI provides historical space weather measurements from the Space Environment Monitor suite on SMS and GOES 1–15 satellites. It includes particle measurements, magnetic field readings, solar irradiance data, and images of the Sun recorded since July 1974.
The page organizes data by satellite with launch, first-data, last-data, and available-instrument listings, along with documentation and ephemeris sections. Use is affected by temporary NCEI cloud-migration access delays, gaps in irradiance and imaging data around the equinoxes, and possible data anomalies that require corroboration with other sources.
