Short summary

We describe a new instrument developed to observe ambient atmospheric aerosol extinction spectra from 300 to 700nm. Laboratory tests were performed to demonstrate that the instrument compares well with theoretical calculations over that spectral range, as well as with commercially available instrumentation measuring aerosol extinction at three visible wavelengths. The unique spectral data will be used to explore linkages between ambient aerosol optical properties, chemistry, and microphysics.
