中文摘要：

在与附近新一代天气雷达对比的基础上,利用自2013年6月起中国科学院大气物理研究所的三部X波段天气雷达在江苏开展了组网观测试验的观测资料,初步对雷达的探测能力和雨区衰减做了分析和订正,同时使用了中国气象科学研究院三维组网系统,将X波段天气雷达与业务雷达资料组网,探索了X波段天气雷达的对业务雷达的补充效果。结果表明：（1）X波段天气雷达的观测数据分别受到了地物回波、遮挡及雨区衰减的影响,已对基数据做了初步的质量控制;（2）通过回波结构和廓线图的对比,经地物抑制、衰减订正等方法质控后的数据存一定范围内具有较高的可靠性,同时三部X波段天气雷达能够有效探测到60 km内的降水结构,其回波分布较为合理,准确的反映了降水区域的特征;（3）将三部X波段天气雷达观测资料与业务中的新一代天气雷达组网后,得到了结构连续、分布更广、平滑作用更低的资料,补充了新一代天气雷达的低空盲区。

英文摘要：

Three X band weather radar developed by Institute of Atmospheric Physics,Chinese Academy of Sciences was the first time used to the multi-radar network test in Jiangsu province from June,2013.Based on the observation data from this network and nearby CINRAD,the detecting capability of X band Doppler radar is analyzed and its attenuation bias is corrected.Through 3D mosaics system from Chinese Academy of Meteorological Science,the networking data is used to explore the operational supplement of X band weather radar for CINRAD.Results indicated that：（1） the ground clutter,blockage,and attenuation have negative effect on the data quality of X band Doppler radar,and preliminary quality control has been applied.（2） From the contrast of echo structures and vertical profiles,the X band radar data is improved through the quality-control method of ground clutter suppression and attenuation correction.And this radar network including 3 radars can get rational precipitation echoes within 60 km,and reflect the precipitation characteristic exactly.（3） After inputting X band radar network and CINRAD data into 3D mosaics system,the echo structure of output data is continuous,with lower smoothing effect and wider radar coverage.The X band radar could be an efficient supplement for CINRAD at low altitude.
