AST-0431503/Cornell: GiovanelliThis Small Grant for Exploratory Research will support preliminary work on establishing the world's largest far infrared/submillimeter telescope. The work will encompass the verification of computational fluid dynamic simulations that suggest that layering of water vapor in the atmosphere is strongly dependent on local topography. Atmospheric water vapor content and layering, in turn, are factors in determining the quality of an observing site, which is a major consideration for astronomical instrumentation.

这项探索性研究的小额拨款将支持建立世界上最大的远红外/亚毫米望远镜的初步工作。这项工作将包括对计算流体动力学模拟的验证，该模拟表明大气中水蒸气的分层强烈依赖于当地地形。大气水蒸气含量和分层反过来又是决定观测地点质量的因素，这是天文仪器的主要考虑因素。
