DESCRIPTION:The Michelson Interferometer for Passive Atmospheric Sounding 
 (MIPAS) instrument onboard the ESA Envisat satellite operated from July 20
 02 to April 2012. The infra-red limb emission measurements compile a uniqu
 e dataset of day and night measurements of polar stratospheric clouds up t
 o the poles. From the spectral measurements in the 4.15-14.6 microns range
  it is possible to select a number of atmospheric window regions and spect
 ral signatures to classify PSC cloud types like nitric acid hydrates\, sul
 furic ternary solution droplets\, and ice particles. The cloud detection s
 ensitivity is similar to space borne lidars\, but MIPAS adds complementary
  information due to its different measurement technique (limb instead of n
 adir) and wavelength region. An overview of previous MIPAS analyses for no
 rthern and southern polar winters as well as more recent results of a new 
 classification approach will be presented.\n
