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.
