IDRA weather radar measurements - day 2018-05-04

Radar range: standard. Max rain level: weak rain. Parent item: IDRA weather radar measurements - month 2018-05 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：弱降雨。父数据集：IDRA气象雷达观测数据——2018年5月。观测仪器：位于卡堡CESAR观测场的IDRA大气雷达。荷兰国际对流与雷雨研究中心（IRCTR）搭建了一套高分辨率雷达系统IDRA（IRCTR 毛毛雨雷达），用于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的大气研究实验场（CESAR, Cabauw Experimental Site for Atmospheric Research）内一座213米高的气象塔塔顶。该选址具备多项核心优势：其一，可削弱地物杂波的干扰，提升观测灵敏度；其二，能够直接获取低层云与雾的水平分布信息；其三，周边布设的多台配套观测仪器可通过协同整合观测数据，助力研究者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网址{http://www.cesar-database.nl}获取。IDRA可提供反射率、平均多普勒速度、多普勒谱宽的水平分布数据，以及差分反射率、线性退偏振比、比差分相位等偏振类观测参数。本数据集收录的观测数据可向全球科研群体免费开放获取。
