Climate Studies at the South Pole

该项目是一个综合研究的光学和物理 无冰雪表面的特性。 它有四个组成部分 这涉及到全球气候变化 被印在记录在南极冰层中的代用数据中。 表面粗糙度（雪层取向）对 反射太阳光的角分布，以及光谱 将测量热红外辐射的分布， 为解释地球提供了必要的知识 辐射收支实验（埃尔贝）卫星数据。 机制 大气气溶胶在雪表面的干沉积将 可以通过观察可渗透的上部积雪中的空气流动来测量， 和白霜样本，并将检查其同位素 混合物. 前者将允许评估 积雪和冰层中的气溶胶浓度 代表大气中的同期浓度，而 后者将产生同位素比的比较研究， 环境空气温度。

This project is an integrated study of the optical and physical properties of the antarctic snow surface. It has four components which concern the processes by which global climatic variability is imprinted into the proxy data recorded in the antarctic ice. The effect of surface roughness (sastrugi orientation) on the angular distribution of reflected sunlight, and the spectral distribution of thermal infrared radiation will be measured to provide the knowledge necessary for the interpretation of Earth Radiation Budget Experiment (ERBE) satellite data. The mechanism of dry deposition of atmospheric aerosols in the snow surface will be measured by observing the air flow in the permeable upper firn, and samples of hoarfrost and will be examined for their isotopic composition. The former will allow the evaluation of the extent to which the concentration of aerosols in the firn and ice represent contemporaneous concentrations in the atmosphere, while the latter will yield a comparative study of isotopic ratios to the ambient air temperatures.
