NASA ESTO's strategic investments in space-based radiometer technology and flight validation

NASA's Earth Science Technology Office (ESTO) performs strategic investments in instrument subsystems, information systems, and most recently the use of Cube Sat platforms to advance the technology readiness level (TRL) of relevant Earth Science Decadal Survey technologies to reduce and retire risk before infusion into flight missions. In this talk we describe the ESTO philosophy to strategic investment focusing on radiometer technology development and testing including new work involving spaceborne flight validation of radiometer technologies using CubeSats.
