Seminar Abstract:

LASP has a long history of measuring the Sun’s radiant energy from high-altitude balloons, sounding rockets, and from satellite platforms in order to understand its influences on Earth’s environment. In the very near term, LASP will measure the Sun’s energy output from a new frontier – the International Space Station – with the launch of the Total and Spectral Solar Irradiance Sensor (TSIS) at the end of November 2017. LASP’s expertise in precision measurements of the Sun has also enabled technological advances for measuring reflected solar radiation, that portion of the Sun’s energy that escapes back to space after interactions with Earth’s atmosphere and surface elements. By using the Sun as a direct calibration source, the Reflected Solar (RS) spectrometer currently being built by LASP engineers for NASA’s CLARREO Pathfinder mission will reduce the uncertainties in measured solar reflectance by approximately an order of magnitude compared to current sensors. The high-accuracy RS measurements will be used to improve the quality of other NASA sensors and for the attribution, testing, and validation of climate change predictions.

Come learn how LASP is contributing to space measurements of Earth’s energy balance with the TSIS and CLARREO Pathfinder missions. Along the way, see fun videos of the TSIS platform during testing as it is prepared for launch.
