AB: The ACE Fourier Transform Interferometer was launched on SCISAT on August 12, 2003 to make solar occultation measurements. This high spectral resolution (0.02 cm$^{-1}$) instrument has broad spectral coverage (750-4100 cm$^{-1}$). In the work presented here, we will discuss the potential of ACE measurements for characterizing stratospheric sulfate aerosol (SSA) and polar stratospheric clouds. Previously reported studies showed that the high spectral resolution solar occultation measurements of ATMOS, which have limited spectral coverage, can be used to characterize SSA composition under high and moderate loadings. It has also been shown that MkIV airplane-based measurements, with a spectral range similar to ACE, have use in characterizing aerosol size. The work presented here is a sensitivity study of ACE measurements to characterize aerosol size and composition under current aerosol loading conditions and higher aerosol loadings.
