地面观测站

There are three kinds of observation data: remote sensing observation data, radiosonde report and surface observation data.

目前，中尺度数值模式中用到的观测资料包括：遥感观测资料以及常规探空和地面观测(地面观测站与地面自动站)资料等。

Astrometry with new technologies created and is dedicated to the Space Telescope astrometric space orbit around the Earth observation and research on the scientific .1989 8 8, the European Space Agency launch astrometric Satellite Iba Valley satellite, which contains a 29 cm diameter reflecting telescope, four ground stations for data reception and analysis with the aim of space-based observations compiled by 120,000 to contain space for satellite measurement of star form, the location accuracy of ± 0002, parallax measurement accuracy ± 0002, on their own a year 0002, CDCDCD preliminary estimate of the above three data are now actual for the 0004,0003 and 0005; CDCDCD190 year in April the U.S. launch of the Hubble Space Telescope, containing 24 m diameter Wang C far mirror can work 15-20 years, 17-18 so you can measure the parallax of stars, are hundreds of thousands of stars of the measurement results.

伴随天体测量新技术而产生，是专门用于天体测量的空间望远镜在围绕地球的空间轨道上进行观测研究的科学。1989年8月8日，欧洲空间局发射天体测量卫星伊巴谷号卫星，它载有口径29厘米反射望远镜，4个地面观测站进行资料接收与分析，目的是要通过空间观测编出含星12万颗的空间测量星表，位置精度为±0002，测量视差的精度为±0002，自行为每年0002，CDCDCD现在初步估计上述三个数据实际为0004、0003和0005；CDCDCD190年4月美国发射哈勃空间望远镜，载有口径24米的望C远镜，可工作15—20年，可以测量出17—18等星的视差，得到几十万颗星的测量结果。

The wind fields andtemperature fields data provided by "D files" from 14 surface observationstations around Beijing area are used to produce the mean wind fields and the meantemperature fields over Beijing area in summer and winter. Such results are gotten:(1)Due to the unique topography the wind of Beijing area during the day time is southernanabatic wind and in the night is northern katabatic wind in summer.

Keywords：wind field； temperature field； urban heat island； urban boundarylayer； Beijing area 北京区域夏冬季风场、温度场的观测研究胡小明刘树华梁福明王建华刘和平王迎春李炬摘要：用北京及市郊地区共14个地面气象观测站的全月数据顺序文件&D文件&提供的风场及温度资料，采用逐时月均匀的方法对北京及周边地区的冬夏两季的风场，温度场特征进行了研究。

Of course, it has been extensively studied with ground-based observatories.

当然，它已被广泛研究的地面观测站。
