Laboratory studies of ice formation pathways from ammonium sulfate particles
ice formation pathways ammonium sulfate particles
2009/3/13
Cirrus clouds are composed of ice particles and their formation pathways have been studied extensively in the laboratory. The ability of ammonium sulfate particles to act as nuclei for cirrus clouds h...
Chemical characteristics of ice residual nuclei in anvil cirrus clouds: evidence for homogeneous and heterogeneous ice formation
ice residual nuclei anvil cirrus clouds homogeneous and heterogeneous ice formation
2009/2/16
A counterflow virtual impactor was used to collect residual particles larger than about 0.1 μm diameter from anvil cirrus clouds generated over Florida in the southern United States. A wide variety of...
The role of organic aerosols in homogeneous ice formation
organic aerosols homogeneous ice formation
2009/2/7
Recent field observations suggest that the fraction of organic-containing aerosol particles in ice cloud particles is diminished when compared to the background aerosol prior to freezing. In this work...
