IDRA weather radar measurements - month 2013-07

Parent item: IDRA weather radar measurements - all data Detailed observation of the spatial and temporal distribution of rainfall and drizzle, measured by IDRA (IRCTR Drizzle Radar) at Cabauw, Lopik, Netherlands. This is a growing time series of datasets, updated every few months. 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.父数据集：IDRA气象雷达测量全数据 本数据集依托荷兰卡堡（Cabauw）与洛皮克（Lopik）地区的IDRA（IRCTR Drizzle Radar）开展观测，旨在精细化解析降雨与毛毛雨的时空分布特征。 本数据集为持续扩容的时序数据集，每数月更新一次。 观测设备：部署于卡堡大气研究实验站（Cabauw Experimental Site for Atmospheric Research，简称CESAR）观测场内的IDRA大气雷达。荷兰大气与热带海洋研究中心（IRCTR）搭建了这套高分辨率雷达系统IDRA，其核心目标为精细化观测降雨与毛毛雨的时空分布规律。 该系统于2007年8月末部署于荷兰卡堡的CESAR观测场内一座213米高的气象塔塔顶。 该选址具备多重优势：其一，可有效抑制地面杂波干扰，提升观测灵敏度；其二，可直接获取低层云与雾的水平分布观测结果；其三，观测站周边配套了多台其他观测仪器，通过多源数据协同分析可深化对大气物理过程的认知。 CESAR观测站其他设备的观测数据可通过网址{http://www.cesar-database.nl}获取。 IDRA可输出反射率、平均多普勒速度、多普勒谱宽等核心雷达参量，以及差分反射率、线性退极化比、特定差分相位等偏振探测参量的水平分布数据。 本数据集所收录的全部观测数据面向全球科研群体免费开放共享。
