Extreme Ultraviolet and X-ray Irradiance Sensors Image Gallery

The GOES-R Series Extreme Ultraviolet and X-ray Irradiance Sensors (EXIS) instrument is critical in aiding NOAA's efforts to understand and monitor solar irradiance in the upper atmosphere, that is, the power and effect of the sun’s electromagnetic radiation per unit of area. EXIS detects solar flares that could interrupt communications and reduce navigational accuracy, affecting satellites, high-altitude airlines, and power grids on Earth.
