Enhancing Solar Observations from GOES-R: Derived Products from the Extreme Ultraviolet and X-Ray Irradiance Sensors (EXIS) and Solar Ultraviolet Imager (SUVI)

The Geostationary Operational Environmental Satellite (GOES) R-Series feature two solar-pointing instruments, the Extreme Ultraviolet and X-Ray Irradiance Sensors (EXIS) and the Solar Ultraviolet Imager (SUVI). NOAA's National Centers for Environmental Information (NCEI) is responsible for creating the derived EXIS and SUVI products that forecasters will use to interpret solar events. NOAA is scheduled to begin using these products operationally within the next year, at which point it will also make the data publicly available. This presentation highlights how the derived EXIS and SUVI products improve upon older GOES observations. For EXIS, new products include one-second X-ray fluxes, flare location, solar flare detection, extreme ultraviolet (EUV) line irradiances, the Mg II index, and a modeled EUV spectrum. SUVI improvements include running difference images, which visually highlight changes on the solar disk, and automated high-cadence solar maps that classify regions by activity type.
