IDRA weather radar measurements - day 2011-08-03

Radar ranges: standard, far. Max rain level: moderate rain. Parent item: IDRA weather radar measurements - month 2011-08 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、远量程。最大降雨等级：中雨。父项：IDRA气象雷达观测数据——2011年8月。测量仪器：位于荷兰卡堡（Cabauw）的CESAR（大气研究卡堡实验场，Cabauw Experimental Site for Atmospheric Research）观测站内的IDRA大气雷达。IRCTR构建了高分辨率雷达系统IDRA（IRCTR 细雨雷达），旨在精准观测降雨与细雨的时空分布特征。该系统于2007年8月末部署在荷兰卡堡的213米高气象塔塔顶。该选址具备多重优势：其一，可降低地面杂波影响，提升探测灵敏度；其二，可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通过协同整合观测数据，助力研究者深入理解大气物理过程。CESAR观测站其他仪器的相关数据可访问{http://www.cesar-database.nl}。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、线性退极化比、比差分相位等偏振参数的水平分布数据。所采集的科研数据可对全球科学界免费开放获取。
