【 摘 要 】

Microphysical modeling of cloud formation and growth relies on fundamental measurements of the properties of condensable gases which form cloud particles. NASA's Ames Chemistry Laboratory has the capability to measure vapor pressures and heterogeneous nucleation conditions for a variety of gases found in the atmospheres of solar system bodies. Highlights from work for Earth, Mars, and Titan demonstrate the range of conditions and atmospheres studied to date.
