IDRA weather radar measurements - day 2013-02-03

Radar range: standard. Max rain level: moderate rain. Parent item: IDRA weather radar measurements - month 2013-02 Measuring instrument: IDRA atmospheric radar in CESAR observatory, Cabauw IRCTR has built a high resolution radar system, IDRA (IRCTR Drizzle Radar), aimed at the detailed observation of the spatial and temporal distribution of rainfall and drizzle. The system was placed at the end of August 2007 on top of a 213 m high meteorological tower in the CESAR (Cabauw Experimental Site for Atmospheric Research) observatory in Cabauw, The Netherlands. This location has several advantages: In the first place, an increased sensitivity due to the reduction of the influence of ground clutter. Secondly, it allows direct observation of the horizontal distribution of low level clouds and fog. Finally, the presence of other instruments in the vicinity enhances the understanding of the physical processes in the atmosphere by synergistically combining their measurements. Data from other instruments at CESAR are available at {http://www.cesar-database.nl}. IDRA provides the horizontal distribution of reflectivity, mean Doppler velocity, Doppler spectrum width and polarimetric parameters like differential reflectivity, linear depolarization ratio or specific differential phase. The data collected is freely available to the scientific community.雷达量程：标准量程。最大降雨等级：中雨。父数据集项：IDRA气象雷达观测数据——2013年2月。测量仪器：位于荷兰卡堡市CESAR（卡堡大气研究实验场，Cabauw Experimental Site for Atmospheric Research）观测场的IDRA大气雷达。IRCTR研发了一套高分辨率雷达系统IDRA（IRCTR毛毛雨雷达，IRCTR Drizzle Radar），旨在精准观测降雨与毛毛雨的时空分布特征。该系统于2007年8月末部署于荷兰卡堡市CESAR观测场内一座213米高的气象塔楼顶部。该观测点位具备多重优势：其一，可通过削弱地面杂波影响提升观测灵敏度；其二，可直接观测低层云与雾的水平分布特征；其三，观测场周边部署的其他仪器可通过数据协同融合，助力科研人员深入解析大气物理过程。CESAR观测场其他仪器的观测数据可通过{http://www.cesar-database.nl}获取。IDRA可输出反射率（reflectivity）、平均多普勒速度（mean Doppler velocity）、多普勒谱宽（Doppler spectrum width）的水平分布场，以及差分反射率（differential reflectivity）、线性退极化比（linear depolarization ratio）、差分相移率（specific differential phase）等偏振观测参数。本数据集采集的全部观测数据面向全球科研群体免费开放。
