Seminar Abstract:

On January 25, 2003, NASA’s Solar Radiation and Climate Experiment (SORCE) spacecraft was launched into space on a Pegasus XL launch vehicle that carried four instruments: the Total Irradiance Monitor (TIM), Solar Stellar Irradiance Comparison Experiment (SOLSTICE), Spectral Irradiance Monitor (SIM), and Extreme Ultraviolet Photometer System (XPS). The primary objective for SORCE is to measure important solar input to Earth’s radiation budget and to relate how solar variability influences our atmosphere and climate. SORCE has now contributed to fifteen years of precise measurements for the important sun-climate records of the Total Solar Irradiance (TSI) and Spectral Solar Irradiance (SSI). This presentation will provide an overview of the SORCE mission, some science highlights, and the phoenix-rebirth story for the SORCE operations.
