The group is cited for the development and deployment of innovative chip-scale sensors for the continuous measurement of the infrared to ultraviolet solar radiation that drives the Earth's climate system. The sensors have been successfully deployed on two CubeSat miniature satellites presently in orbit, demonstrating that accurate long-term solar measurements are possible at a cost one-tenth that of traditional technologies, but with a similar level of accuracy. These sensors will perform space-based measurements of the Earth's energy balance, a critical climate variable, for coming decades.
