Abstract : Accurate solar extreme ultraviolet (EUV) spectral irradiance data are needed for research in solar, ionospheric/thermospheric, and planetary physics, as well as for space weather forecasts and spacecraft operations and tracking. Because of instrument performance degradation, in orbit radiometric recalibration methods and capability are a fundamental prerequisite for such measurements. In this laboratory research program, we studied methods for in-orbit radiometric intercomparisons and calibration, and collaborated in the radiometric calibration of the Ultraviolet Coronagraph Spectrometer (UVCS) now observing the solar corona from the ESA/NASA SOHO mission.
