摘要：

越来越多的观测证据表明, 昆仑站所在的冰穹A地区在光学、红外和太赫兹等波段都有着地面最佳的天文观测条件。它具有优异的自由大气视宁度, 极低的可沉降水汽含量, 非常暗的夜天光背景, 以及连续数月的极夜可观测时间等。通过对最近17年的工作总结, 着重介绍冰穹A全面的台址测量工作, 并展示测量结果以及最新的进展。

Abstract:

More and more observational evidence has demonstrated that the Dome A region where Kunlun Station is located has the best ground-based astronomical observation conditions in optical, infrared, and terahertz wave bands. It has excellent free-atmosphere seeing, extremely low precipitable water vapor, a very dark sky background at night, and months of continuous observation time during polar nights. Through a summary of work in the past seventeen years, this article focuses on the comprehensive site survey work at Dome A and presents the measurement results as well as the latest progress.
