项目摘要

Carrying out a satellite study of cloud cover and water vapor in northern Chile, we have selected Co. Chajnantor at an altitude of 5600m as a candidate site where TAO (university of Tokyo Atacama Observatory) 6.5m infrared telescope be installed. However, it is not feasible to observe, with satellites from space, the local weather conditions near the surface of the ground which would seriously differ from those observed from space. Thus it is vital to monitor the weather on site and to prove that the summit of Co. Chajnantor is an ideal site for the TAO telescope. In this research study, we have installed a standard weather measuring pole, seeing monitor, and cloud monitors on the summit, and measured clouds near the ground, seeing, wind velocities, etc., on which performance in astronomical observation should seriously depend.We have made :1.The weather conditions were measured with the cloud monitors, the weather monitoring pole, and the seeing monitor which were in stalled at an alt … More itude of 5000m until 2005.2.We have opened up a path to which is used to transport, from the mountain foot at 5000m to the summit at 5600m, personnel, instrument, and other materials in 2006.3.The cloud monitors, the weather monitoring pole, and the seeing monitor were transported to the summit in 2006, and the measurements started on the summit.4.The data thus acquired were analyzed.5.We have made some study related to the science which can only be carried out on this 5600m altitude site.The results are as follows. Cloud cover measured on the summit is the same as that measured at a 5000m altitude, and wind velocity at a 5600m altitude is within a tolerable range for telescope operation. Seeing measured on the summit has recorded a splendid value of 0.4 arcsec, nonetheless the measurements were made at a point where air turbulence is apt to occur. Here we conclude that it has been proven that the summit of Co. Chainantor is one of the world-best places for infrared astronomy, and thus for a site of the TAO 6.5m telescope. The goal of this study has been achieved. Less

在智利北方进行云量和水汽的卫星研究时，我们选择了海拔5600米的Chajnantor公司作为安装TAO（东京大学阿塔卡玛天文台）6.5米红外望远镜的候选地点。然而，用卫星从空间观测地面附近的当地天气状况是不可行的，因为这与从空间观测到的情况有很大不同。因此，至关重要的是要监测现场的天气，并证明Chajnantor公司的首脑会议是一个理想的网站为TAO望远镜。在这次研究中，我们在山顶安装了标准的气象测量杆、视宁度监测仪和云监测仪，测量了近地面的云、视宁度、风速等，我们做了以下工作：1.用高空悬挂的测云仪、测天气杆和视宁度仪测量天气状况 ...更多信息 2.2006年开辟了5000米山脚至5600米山顶人员、仪器等物资运输通道。3.2006年将云监测仪、气象监测杆、视宁度监测仪运至山顶。4.对所获得的数据进行了分析。5.我们进行了一些只有在5600米的高度上才能进行的科学研究。山顶测得的云量与5000米高度测得的云量相同，5600米高度的风速在望远镜操作的容许范围内。在山顶上测量的视宁度记录了0.4角秒的辉煌值，尽管如此，测量是在容易发生空气湍流的地方进行的。在这里，我们得出结论，它已被证明，该首脑会议的公司Chainantor是世界上最好的地方之一，红外天文学，因此为网站的TAO 6.5米望远镜。本研究的目的已经达到。少
