SPEXone: Dutch Instrument Arrives for PACE Mission

Aerosols are small solid or liquid particles suspended in the air that affect climate change directly throuhg interaction with solar radiation. Aerosols affect climate indirectly by changing the micro-and macro- physical properties of clouds. Scientists who study climate change rely on detailed data to properly characterize the the amount of radiative forcing that aerosols cause. SPEXone is a new instrument designed to pursue that data with superb accuracy. It's a polarimeter, intended to measure the intensity, Degree of Linear Polarization (DoLP) and Angle of Linear Polarization (AoLP) of sunlight reflected back from Earth's atmosphere, land surface, and ocean. Built by engineers at The Netherlands Institute for Space Research (SRON) and Airbus Defence and Space Netherlands (Airbus DS NL), SPEXone will fly on the PACE spacecraft as one of that mission's suite of sensors.
