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，在西伯利亚、蒙古、中国、西藏和泰国精心挑选的地点建立了15个自动气象站，积累了宝贵的能量平衡数据。由于测站部署在地理上非常不同的位置，地表能量分配制度在时间和量级上的变化都有所不同。此外，还比较了AAN地面站、GAME和ECMWF再分析资料得到的地表通量，结果表明，测量值与模式导出值有很好的一致性。此外，已发现AAN数据对模型验证很有用，因为AAN站点覆盖了广泛的地理区域和气候，将模型或卫星产生的任何变量与AAN数据集进行比较，将有机会彻底验证这些数据(反过来，模型或卫星测量本身)。天网是一个…的网络更多的天空辐射计和天网站点是SRI Samrong(泰国，1997年7月以来)、寿县(中国，1999年3月至1999年3月)/合肥(中国，1999年4月起)在SRI Samrong安装了激光雷达和微波辐射计。根据GMS可见光和红外辐射数据估算了地面太阳辐射，并与GAME高精度辐射站点和天网站点的观测值进行了比较。1997、1998和1999年地面辐射通量的月平均值与观测值基本一致。通过激光雷达监测，获得了云底高度统计数据。美国国家航空航天局的数据经过了核查和处理，因为它们是从每个站点提供的，以便在筑波大学陆地环境研究中心的美国国家航空航天局数据中心存档，并通过美国航空航天局的网站http://www.suiri.tsukuba.ac.jp/Project/aan/aan.html.向科学界开放此外，还制作了光盘，分发给无法轻松进入数据中心的国家。较少
