IDRA weather radar measurements - day 2015-11-10

Radar range: standard. Max rain level: moderate rain. Parent item: IDRA weather radar measurements - month 2015-11 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——2015年11月。
观测仪器：位于荷兰卡堡（Cabauw）的IDRA大气雷达，部署于CESAR天文台。
IRCTR研发了一套高分辨率雷达系统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化观测。
该系统于2007年8月底部署在荷兰卡堡市CESAR（卡堡大气研究实验场，Cabauw Experimental Site for Atmospheric Research）天文台内一座213米高的气象铁塔顶部。
该选址具备多重优势：其一，可削弱地面杂波影响，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，周边配备多台其他观测仪器，通过协同整合多设备的观测数据，可深化对大气物理过程的认知。
CESAR天文台的其他仪器观测数据可通过链接{http://www.cesar-database.nl}获取。
IDRA可提供反射率、平均多普勒速度、多普勒谱宽等雷达回波参数的水平分布数据，同时输出差分反射率、线性退极化比、差分相移率等极化观测参数。
本数据集所采集的观测数据向全球科研社群免费开放。
