Remote sensing spectroscopy is a powerful technique for the measurement of atmospheric species and aerosols that affect air quality and ozone chemistry in Earth's atmosphere. At JPL's Table Mountain Facility, we operate state-of-the-art spectrometers for passive atmospheric composition measurements by measuring direct and scattered light from the Sun and Moon. Techniques such as high-resolution spectroscopy and spectropolarimetry enable the measurement of important trace molecules that affect air quality such as O3, OH, NO2, NO3, BrO, IO, SO2, HCHO as well as species that affect climate change such as water vapor, CO2, CH4 and aerosols. The data are analyzed in collaboration with atmospheric modeling groups to improve our understanding of changes in atmospheric chemistry and transport, and to validate the measurements of satellite remote sensing instruments.
