Measurements of heat and water exchange will then be taken from satellites , planes , ships and ground stations within a 250 km 155 mile radius 有关人员将通过分布于半径为250公里范围内的人造卫星飞机轮船及地面观测站来接收这些气球到的云层内热量和水分的变化数据。
Observatories watched the event from earth and scientists hoped the cloud of dust and debris would provide clues to the geological composition of the site 很多观测站在地表观测了撞击全过程，科学家希望撞击所激起的尘云和碎石能为研究“卓越湖”区域的地质构成提供依据。
Apart from a break during the second world war , the frequency of observations , the number of observing stations and the number of meteorological elements observed increased through the years 除了第二次世界大战期间一度中断外，观测次数观测站数目及气象要素的观测项目历年来都有所增加。

The data are then routed via the global telecommunications system to guangzhou . the locations of the four manned stations , the 27 " full " automatic weather stations , and the nine anemometer stations are shown in figure 1 除雨量站和支援风分析系统的测风站外，图一显示上述各观测站的位置。

At the middle scale is the plate boundary level , where the plate boundary observatory ( pbo ) will image and characterize the slow deformation of the earth along the western u . s . and alaska 中级尺度是板块交界，在此，板块交界观测站（ pbo ）将沿着美国西部与阿拉斯加，拍摄并描绘出地球缓慢变形下的特性。
With only bearing information observability of the problem completely depends on certain kind of maneuver of the observer which distinguishes bot from other tma problems 由于只利用单一观测站测量得到的方位信息不能获得雷达站的距离信息，因此要实现对雷达站的跟踪就必须保证观测器具备某种形式的机动性。
All three observatories measure ripples in the fabric of spacetime known as gravitational waves . the waves are detected with perpendicular pairs of laser beams located at each facility 这三个观测站对时空结构中的波纹也就是我们所说的引力波进行测量。各个观测站均使用一对相互垂直的激光束用来探测引力波。
