      abstract     = {The homogeneous freezing of supercooled H2SO4/H2O solution
                      droplets was investigated in the aerosol chamber AIDA
                      (Aerosol Interactions and Dynamics in the Atmosphere) of
                      Forschungszentrum Karlsruhe. 24 freezing experiments were
                      performed at temperatures between 189 and 235 K with aerosol
                      particles in the diameter range 0.05 to 1 mum. Individual
                      experiments started at homogeneous temperatures and ice
                      saturation ratios between 0.9 and 0.95. Cloud cooling rates
                      up to -2.8 K min(-1) were simulated dynamically in the
                      chamber by expansion cooling using a mechanical pump.
                      Depending on the cooling rate and starting temperature,
                      freezing threshold relative humidities were exceeded after
                      expansion time periods between about 1 and 10 min. The onset
                      of ice formation was measured with three independent methods
                      showing good agreement among each other. Ice saturation
                      ratios measured at the onset of ice formation increased from
                      about 1.4 at 231 K to about 1.75 at 189 K. The experimental
                      data set including thermodynamic parameters as well as
                      physical and chemical aerosol analysis provides a good basis
                      for microphysical model applications.},
