ABSTRACT
Liquid aerosol particles and ice crystals in subvisible cirrus clouds in the tropopause region are investigated in terms of microphysical, chemical, and optical properties. These particle properties are examined by means of a thermodynamic equilibrium model and are related to satellite extinction measurements.
