The Spectral Aerosol Extinction (SpEx) is a ground-based in situ spectrometer that measures ambient aerosol extinction. It is a modified aerosol extinction differential optical absorption spectrometer (AE-DOAS) with faster data acquisition and increased sensitivity. It measures aerosol extinction in the 300 to 700 nm wavelength range at a spectral resolution of about 0.7 nm. SpEx provides intensity spectra every 125 seconds and aerosol extinction every 250 seconds.
