DDW1型闪电定位仪数据质量分析评估

Data quality analysis and evaluation of DDW1 lightning locator

文章分析了DDW1型闪电定位仪的探测原理,通过分析江苏省DDW1型闪电定位仪试运行期间的雷电数据,并对比DDW1型与ADTD型闪电定位仪的雷电探测类别与数量。结果表明:除个别站点因网络问题导致传输数据到报率略低外,其余站点数据到报率均达到99%;与ADTD型闪电定位仪相比,DDW1型闪电定位仪灵敏度更高,所探测到的正闪数量是ADTD型闪电定位仪的5.8倍,负闪数量二者相差不大,DDW1型闪电定位仪正闪与负闪比为1∶1.8。研究结果为DDW1型闪电定位仪的推广应用奠定基础。

In this paper,the detection principle of DDW1 lightning locator is introduced.By analyzing the lightning data during the trial operation of DDW1 lightning locator in Jiangsu Province,and comparing the detection category and quantity with slightly lower transmission data reporting rates of DDW1 and ADTD lightning locators,the results show that except for a few stations due to network problems,the others all reach 99%.Compared with ADTD lightning locator,DDW1 lightning locator has higher sensitivity,and the number of positive lightning detected is 5.8 times that of ADTD lightning locator,and the number of negative flashes is not significant between the two,and the ratio of positive and negative flashes of DDW1 lightning locator is 1∶1.8.The research results lay a foundation for the promotion and application of DDW1 lightning locator.
