IDRA weather radar measurements - day 2013-11-28

Radar range: standard. Max rain level: weak rain. Parent item: IDRA weather radar measurements - month 2013-11 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：小雨。父数据集：IDRA气象雷达观测数据——2013年11月。测量仪器：荷兰卡堡CESAR观测站内的IDRA大气雷达。IRCTR研制了一套高分辨率雷达系统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特征。该系统于2007年8月末部署在荷兰卡堡的CESAR（卡堡大气研究实验场，Cabauw Experimental Site for Atmospheric Research）观测站内一座213米高的气象塔塔顶。该观测点位具备多重优势：其一，可降低地面杂波影响，提升探测灵敏度；其二，能够直接观测低层云与雾的水平分布；其三，观测站周边搭载的其他仪器可与本系统协同整合观测数据，助力研究者深入解析大气物理过程。CESAR观测站其他配套仪器的观测数据可通过{http://www.cesar-database.nl}获取。IDRA雷达可输出反射率、平均多普勒速度、多普勒谱宽以及差分反射率、线性退偏振比、比差分相位等偏振参量的水平分布数据。本数据集所收录的观测数据可面向科研社群免费开放获取。
