Ice nucleation experimental and modelling research (Murray and Dobbie) Institute for Climate and Atmospheric Science (ICAS) Ice nucleation experimental and modelling research (Murray and Dobbie) AIDA Chamber, Karlsruhe Cloud Processing Chambers, Leeds Hom and het nucleation studies. Glassy aerosol act like het ice nuclei: They nucleate ice at 120% RHI compared to 160% in non-glass state. Murray et al., Nature Geoscience, 2010

Modelling work (Dobbie) Institute for Climate and Atmospheric Science (ICAS) Modelling work (Dobbie) Glassy particles incorporated into cirrus modelling studies (APSC). Results: - mean ice size a factor of 2 larger - Ice num an order of magnitude lower - May explain the high in-cloud ice super-saturations Leeds cirrus modelling APSC (1D high resolution detail microphysics model – e.g. glassy study) LEM (1/2/3D cloud scale modelling – e.g. GCSS WG cirrus, ASCOS) UM (updating UM for contrail cirrus for COSIC) Optical property calculations using observed ice habits Radiative properties (Fu-Liou & E-S models) Various studies coupling modelling, experimental, and field campaigns
