IDRA weather radar measurements - day 2016-07-12

Radar range: far. Max rain level: strong rain. Parent item: IDRA weather radar measurements - month 2016-07 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.雷达作用距离：远距。最大降雨等级：强降雨。父数据集：IDRA气象雷达观测数据集——2016年7月。观测仪器：位于卡堡CESAR观测站内的IDRA大气雷达。由IRCTR研发的高分辨率雷达系统IDRA（IRCTR毛毛雨雷达），旨在精细化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地区的CESAR（卡堡大气研究实验场，Cabauw Experimental Site for Atmospheric Research）观测站内一座213米高的气象铁塔顶端。该点位具备多项显著优势：其一，可降低地面杂波影响，提升观测灵敏度；其二，可直接观测低层云与雾的水平分布；其三，观测站周边配备多台配套仪器，通过协同融合多源观测数据，可深化对大气物理过程的理解。CESAR观测站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、平均多普勒速度、多普勒谱宽等参数，以及差分反射率、线性退偏振比、比差分相位等偏振特性参数。所采集的观测数据面向科研群体免费开放。
