A collection of in situ solar irradiance observations and sun diagrams made at various locations, including the United States, Western Pacific ocean, Antarctica, and Swan Island, Honduras. Charts include long-roll autographic charts, circular charts, and 'boomerang' charts, with most stations discontinuing autographic chart use in the mid-1980s. The organization listed is NOAA_NCEI.
Use Cases
- Analyze historical solar irradiance trends based on in situ observations
