      abstract     = {We have analyzed mid-infrared limb-emission measurements of
                      polar stratospheric clouds ( PSCs) by the Michelson
                      Interferometer for Passive Atmospheric Sounding ( MIPAS)
                      during the Antarctic winter 2003 with respect to PSC
                      composition. Coincident Lidar observations from McMurdo were
                      used for comparison with PSC types 1a, 1b and 2. Application
                      of new refractive index data of beta-NAT have allowed to
                      accurately simulate the prominent spectral band at 820
                      cm(-1) observed by MIPAS at the location where the Lidar
                      instrument observed type 1a PSCs. Broadband spectral fits
                      covering the range from 780 to 960 cm(-1) and from 1220 to
                      1490 cm(-1) showed best agreement with the MIPAS
                      measurements when spectroscopic data of NAT were used to
                      simulate the MIPAS spectra. MIPAS measurements collocated
                      with Lidar observations of Type 1b and Type 2 PSCs could
                      only be reproduced by assuming a composition of supercooled
                      ternary H2SO4/HNO3/H2O solution ( STS) and of ice,
                      respectively. Particle radius and number density profiles
                      derived from MIPAS were generally consistent with the Lidar
                      observations. Only in the case of ice clouds, PSC volumes
                      are partly underestimated by MIPAS due to large cloud
                      optical thickness in the limb-direction. A comparison of
                      MIPAS cloud composition and Lidar PSC-type determination
                      based on all available MIPAS-Lidar coincident measurements
                      revealed good agreement between PSC-types 1a, 1b and 2, and
                      NAT, STS and ice, respectively. We could not find
                      spectroscopic evidence for the presence of nitric acid
                      dihydrate ( NAD) from MIPAS observations of PSCs over
                      Antarctica in 2003.},
