IDRA weather radar measurements - month 2014-05

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气象雷达测量全量数据。本数据集由位于荷兰洛皮克地区卡堡的IDRA（IRCTR毛毛雨雷达，IRCTR Drizzle Radar）采集，用于精细观测降雨与毛毛雨的时空分布特征。本数据集为持续更新且规模逐步扩大的时序数据集，每数月更新一次。本次数据集的采集设备为位于卡堡CESAR（Cabauw大气研究实验场，Cabauw Experimental Site for Atmospheric Research）观测站内的IDRA大气雷达。IRCTR研发了高分辨率雷达系统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规律。该系统于2007年8月底部署于荷兰卡堡的CESAR观测站内一座213米高的气象铁塔顶部。该观测站点具备多项核心优势：其一，可削弱地面杂波影响，提升探测灵敏度；其二，可直接观测低层云与雾的水平分布特征；其三，观测站周边部署了多台其他观测仪器，通过协同整合多源观测数据，可深化对大气物理过程的认知。CESAR观测站其他仪器的观测数据可通过链接{http://www.cesar-database.nl}获取。IDRA可输出反射率、平均多普勒速度、多普勒谱宽等雷达基本参量，以及差分反射率、线性退极化比、差分相移率等偏振参量的水平分布数据。本数据集所采集的全部数据均对全球科学界免费开放。
