IDRA weather radar measurements - day 2014-06-21

Radar range: standard. Max rain level: weak rain. Parent item: IDRA weather radar measurements - month 2014-06 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——2014年6月。测量仪器：位于荷兰卡堡CESAR观测场的IDRA大气雷达。IRCTR已搭建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月底部署在荷兰卡堡的卡堡大气研究试验场（Cabauw Experimental Site for Atmospheric Research，简称CESAR）观测场内一座213米高的气象塔塔顶。该观测点位具备多重优势：其一，地面杂波影响得以削弱，系统灵敏度提升；其二，可直接观测低层云和雾的水平分布特征；其三，周边配备的其他观测仪器可与本系统协同联动，通过融合多源观测数据加深对大气物理过程的认知。CESAR观测场内其他仪器的观测数据可通过{http://www.cesar-database.nl}获取。IDRA可提供反射率因子、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。本数据集所收录的观测数据面向全球科学界免费开放。
