Heterogeneous ice nucleation on solid ammonium sulfate and glutaric acid particles was studied using optical microscopy and Raman spectroscopy. Optical microscopy was used to detect selective nucleati...
Ice nucleation and cloud microphysical properties in tropical tropopause layer cirrus
Ice nucleation cloud microphysical properties tropical tropopause layer cirrus
2010/2/21
In past modeling studies, it has generally been assumed that the predominant mechanism for nucleation of ice in the uppermost troposphere is homogeneous freezing of aqueous aerosols. However, recent i...
