IDRA weather radar measurements - day 2012-11-01

Radar range: standard. Max rain level: moderate rain. Parent item: IDRA weather radar measurements - month 2012-11 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：中雨。父数据集：IDRA气象雷达观测数据——2012年11月。测量仪器：位于荷兰卡堡市CESAR（Cabauw大气研究实验台，Cabauw Experimental Site for Atmospheric Research）观测台的IDRA大气雷达。IRCTR搭建了一套高分辨率雷达系统IDRA（IRCTR Drizzle Radar），旨在对降雨和毛毛雨的时空分布开展精细化观测。该系统于2007年8月底部署于荷兰卡堡市CESAR观测台内一座213米高的气象塔塔顶。该观测点位具备多重优势：其一，可降低地面杂波的影响，提升观测灵敏度；其二，能够直接观测低层云与雾的水平分布特征；其三，周边配备的其他观测仪器可与本系统协同获取数据，助力研究者深入理解大气物理过程。CESAR观测台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、多普勒谱宽以及差分反射率、线性退偏振比、特定差分相位等偏振参数的水平分布数据。本数据集所收录的观测数据可对科学界免费开放获取。
