A new version of the science-quality irradiance data for the GOES-R Extreme Ultraviolet Sensors (EUVS) is now available. This release (Level 2: Version 1.0.7, Level 1b: Version 1.0.5)  includes  the first release of the GOES-19 science-quality EUVS data and has revised calibrations for EUVS-A and -B.  Also, improved spike removal has been implemented for Mg II (EUVS-C) and the responsivity files for EUVS-A have been updated online. We expect to provide another new EUVS version with further improvements in the coming months.

GOES data, plots, documentation, and sample Python code are available at https://www.ncei.noaa.gov/products/goes-r-extreme-ultraviolet-xray-irradiance.  Please contact [email protected] for questions about these measurements or data access.
