IDRA weather radar measurements - month 2017-06

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气象雷达全量观测数据
本数据集针对荷兰卡堡（Cabauw）与洛皮克（Lopik）地区的降雨及毛毛雨时空分布开展精细观测，观测数据由IDRA（IRCTR毛毛雨雷达，IRCTR Drizzle Radar）采集获取。本数据集为持续更新的时序数据集，每数月更新一次。
观测仪器：位于荷兰卡堡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搭建了高分辨率雷达系统IDRA（IRCTR毛毛雨雷达，IRCTR Drizzle Radar），旨在对降雨与毛毛雨的时空分布开展精细观测。该系统于2007年8月末部署于荷兰卡堡CESAR观测场内一座213米高的气象塔楼顶部。
该观测点位具备多项优势：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特征；其三，周边部署的其他观测仪器可与本系统协同获取数据，助力科研人员深入解析大气物理过程。
