                      spectra of supercooled H2SO4/ H2O and HNO3/ H2O solution
                      droplets were recorded in the large coolable aerosol chamber
                      AIDA (Aerosol Interactions and Dynamics in the Atmosphere)
                      of Forschungszentrum Karlsruhe for a range of aerosol
                      compositions and at temperatures extending down to 192 K.
                      The measured spectra were quantitatively analysed in terms
                      of aerosol composition and mass concentration by using Mie
                      theory in combination with published refractive index data
                      as input parameters. Simultaneously, total sulphuric acid
                      and nitric acid mass concentrations from filter analysis and
                      total water concentrations measured with the Lyman-alpha
                      hygrometer of Forschungszentrum Julich were used to
                      calculate the aerosol composition at thermodynamic
                      equilibrium inside the aerosol chamber. By comparing these
                      measured aerosol parameters with those retrieved from the
                      analysis of the FTIR spectra, the accuracy of the literature
                      data sets of refractive indices could be assessed. In
                      summary, four data sets were tested in the H2SO4/ H2O system
                      as well as two data sets in the HNO3/ H2O system, partly
                      revealing significant discrepancies in the retrieved aerosol
                      properties. Potential explanations for these differences are
                      discussed in this paper.},
