Precipitation - radar/gauge 24 hour accumulations over the Netherlands

Gridded files of radar-derived 24 hour precipitation accumulations, corrected by rain gauge data. Radar data from 1500 m over the Netherlands and surrounding area measured are corrected by data from KNMI's 325 manual rain gauges. Time interval is 1 day, from 8 to 8 UTC. KNMI has detected measurement anomalies caused by a defect in some rain gauges for manual precipitation observation. It concerns data from the second half of 2012 until present. At this moment KNMI is assessing the extent of the problem and investigates the options to repair the defect as soon as possible.

雷达数据生成的网格化文件，记录了24小时内的降水累积量，并经雨量计数据进行校正。所测得的荷兰及其周边地区的雷达数据，海拔1500米，经荷兰气象研究所（KNMI）的325个手动雨量计数据校正。时间间隔为1天，从UTC时间8点至8点。荷兰气象研究所已检测到由部分手动降水量观测雨量计缺陷引起的测量异常。此问题涉及自2012年下半年至目前的资料。目前，KNMI正在评估问题的严重程度，并探讨尽快修复缺陷的方案。
