项目摘要

Overall, 15 automatic weather stations were established and valuable energy balance data have been accumulated at carefully selected site in Siberia, Mongolia, China, Tibet, and Thailand. As a result of station deployment in geographically very different locations, difference in variations of surface energy partition regime, both in time and in magnitude were obtained. Also, comparisons of the surface fluxes obtained from one AAN surface station and from GAME and ECMWF reanalysis data were carried out and the results indicate very good agreement of the measurements and model derived values. Also, AAN data have been found useful for a model validation purposes, because AAN sites cover a wide range of geographical areas and climates, a comparison of any variables produced from a model or from a satellite against the AAN data sets should give opportunity for a thorough validation of these data (and, in turn, the model or the satellite measurements themselves). The SKYNET is a network of a … More sky radiometer and SKYNET sites are Sri Samrong (Thailand, since July 1997), Shou-Xian(China, until March 1999) /Hefei (China, from April 1999) A lidar, and a microwave radiometer were installed at Sri Samrong. The surface solar radiation was estimated from GMS visible and infrared radiance data and compared with the values observed at the GAME High Precision Radiation sites and SKYNET sites. Monthly mean values of the surface radiation flux in 1997, 1998, and 1999 are basically in good agreement with the observation. From the lidar monitoring, the cloud base height statistics was obtained. The AAN data have been checked and processed as they are provided from each station for archiving at the AAN data center at Terrestrial Environment Research Center of the University of Tsukuba, and are open to the scientific communities through the AAN web site at http://www.suiri.tsukuba.ac.jp/Project/aan/aan.html. Also a CD-ROM version has been produced for distribution to the countries without easy access to the data center. Less

总体而言，建立了15个自动气象站，并在西伯利亚，蒙古，中国，西藏和泰国精心挑选的地点准确选择了宝贵的能源平衡数据。由于地理位置上的站点部署在截然不同的位置，因此获得了表面能量分配状态的变化差异，无论是在时间和范围内。同样，进行了从一个AAN表面站获得的表面通量以及从游戏和ECMWF重新分析数据中获得的比较，结果表明测量值和模型得出的值非常吻合。此外，已经发现AAN数据可用于模型验证目的，因为AAN站点涵盖了广泛的地理区域和气候，因此比较了从模型或卫星与AAN数据集产生的任何变量的比较，应该为这些数据提供彻底验证的机会（又是模型或卫星测量本身）。天网是一个……更多的天空辐射计的网络，天网和天网站点是斯里·萨姆朗（Sri Samrong）（泰国，自1997年7月以来），舒 - 西安（中国，直到1999年3月） /赫费伊（中国，1999年4月起），在1999年4月起）和微波辐射计安装在Sri Samrong。从GMS可见和红外辐射数据中估算了表面太阳辐射，并将其与在游戏高精度辐射位点和天线位点观察到的值进行了比较。 1997年，1998年和1999年的表面辐射通量的月平均值基本上与观察结果一致。从激光雷达监测中，获得了云碱基高度统计。 AAN的数据已从每个站点提供并进行了处理，以归档Tsukuba大学地面环境研究中心的AAN数据中心，并通过AAN网站http://www.suiri.tsuiri.tsukuba.acukuba.ac.ac.jp/propoproject/aan/aan/aan/aan/aan.html.html.html.html.html.html.htsuiri.tsuiri.tsuiri.tsuiri.tsuiri.tsuiri.tsuiri.tsuiri.tsuiri.tsuiri，还生产了CD-ROM版本，用于向国家分发，而无需轻松访问数据中心。较少的
