Solution coating around ice particles of incipient cirrus clouds.

Kuhs et al. (1) report on the nanometer-scale roughness on the surface of laboratory vapordeposited cubic ice, Ic, and state that such roughness on the surface of cirrus Ic ice particles can influence the surface reactivity, radiative properties, and water vapor uptake coefficient of incipient cirrus clouds. This assumes that the ice surface of cirrus particles is exposed to air. However, this ...

Laboratory measurements of HDO/H2O isotopic fractionation during ice deposition in simulated cirrus clouds.

The stable isotopologues of water have been used in atmospheric and climate studies for over 50 years, because their strong temperature-dependent preferential condensation makes them useful diagnostics of the hydrological cycle. However, the degree of preferential condensation between vapor and ice has never been directly measured at temperatures below 233 K (-40 °C), conditions necessary to fo...
