Description
The Atmospheric Chemistry Experiment (ACE) is comprised of a Fourier transform spectrometer (ACE-FTS) operating in the infrared with broad spectral coverage (750 – 4400 cm-1) and high resolution (0.02 cm-1), a UV-Visible-NIR spectrophotometer (ACE-MAESTRO, Measurement of Aerosol Extinction in the Stratosphere and Troposphere Retrieved by Occultation) with wavelength coverage 280 – 1030 nm and resolution 1 – 2 nm, and a pair of imagers measuring at 525 and 1020 nm, respectively. Collecting solar occultation measurements since February 2004, ACE provides over 19 years’ worth of atmospheric profiles for pressure, temperature, and the volume mixing ratios of more than 30 molecules, as well as volume mixing ratio profiles for more than 20 subsidiary isotopologues. A mission overview will be provided, along with a description of the latest ACE-FTS processing version (version 5.0) and details of recent aerosol studies using ACE-FTS measurements.
