The Geostationary Operational Environmental Satellite (GOES)-R Extreme Ultraviolet and X-Ray Irradiance Sensors (EXIS) suite consists of two main instruments, the Extreme Ultraviolet Sensor (EUVS) and the X-Ray Sensor (XRS). EUVS products include high-cadence and time-averaged measurements of irradiance for seven extreme ultraviolet (EUV) solar lines, the magnesium II core-to-wing ratio (Mg II index), and modeled EUV spectra. XRS products include high-cadence and averaged measurements of soft X-ray solar irradiances for two wavelength bands, flare events, and flare locations.
Product Details
NCEI provides access to operational and science-quality Level 1b (L1b) data, Level 2 (L2) data, documentation, and plots. Users should consult the documentation before using the data. In most cases, the science-quality L2 data are the best option. Example Python codes are provided to give example syntax to read, use, and download these data products. The data files are in NetCDF format.
