SPEX project gets wings: first measurements SPEX airborne published

SRON researchers have published their first results of SPEX airborne--a spectrocalorimeter to measure aerosols. The polarization measurements onboard NASA's research aircraft ER2 prove to be accurate beyond expectations, with an average maximum deviation of 0.5% from reference data. Publication in Applied Optics.

This is an important result because the space version of the spectrocalorimeter--SPEXone--will have to perform flawlessly in 2022 on space mission PACE from NASA. The SPEX concept is also a contender to be part of the future European CO2 space mission.
