The Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado Boulder has an immediate opening for a Solar Physics Research Scientist in solar working with NOAA’s National Centers for Environmental Information’s (NCEI). The position focuses on work related to the solar irradiance monitors on the Geostationary Operational Environmental Satellites Series-R (GOES-R). The GOES-R spacecraft each contain a suite of space weather sensors, including the Extreme Ultraviolet and X-ray Irradiance Sensors (EXIS). The EXIS instrument measures both the X-ray solar irradiance which provides the historical solar flare classifications with the X-ray Sensor (XRS), and the extreme ultraviolet irradiance with the Extreme Ultraviolet Sensor (EUVS). As a part of the NCEI solar irradiance team, the selected candidate will work to improve the in-flight calibration and validation of XRS and EUVS data, develop data tools and products for X-ray and ultraviolet time series datasets hosted at NCEI, and apply XRS and EUVS data to scientific research, all in support of NOAA’s space weather forecasting operations and the scientific community. CIRES Research Associates may pursue external funding for complementary scientific or operational activities, although external funding is not necessary.
