Research Interests

Jimmy is a Solar Physics Research Scientist at CIRES-NOAA/NCEI. In this role, he studies solar irradiance monitors on the Geostationary Operational Environmental Satellite Series-R (GOES-R). The GOES-R spacecraft contains a suite of space weather sensors, including the Extreme Ultraviolet and X-ray Irradiance Sensor (EXIS). The EXIS instrument measures both the X-ray solar irradiance, which measures solar flares, 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, he also improves the in-flight calibration and validation of XRS and EUVS data, develops data tools and products for X-ray and ultraviolet time series datasets hosted at NCEI, and applies XRS and EUVS data to scientific research, all in support of NOAA’s space weather forecasting operations and the scientific community.
