摘要
提出一种基于自回归与反距离加权的空间质量控制方法——AI方法,该方法能够在时间维度和空间维度对气象资料进行质量控制。选择不同地区4个地面气象观测站(南京58238站,连云港58044站,无锡58353站,徐州58027站)2007年逐时气温观测数据作为被控对象,检验该方法在气温资料质量控制中的适用性。通过对添加的随机人为误差的检验发现,该方法能够有效地标记出存疑数据,相对于反距离加权和空间回归,该方法具有更好的检验效果,稳定性高、适应性强,适用于平原或丘陵地带。
A method of spatial quality control（called AI for short）, based on auto-regression and inverse distance weighting（IDW）, is proposed. The method enables quality control of meteorological data in both the temporal and spatial dimension. Aimed at assessing the applicability of the method, in this study, hourly temperature observational data for the year 2007 from four surface meteorological stations in different regions（Nanjing station 58238, Lianyungang station 58044, Wuxi station 58353, and Xuzhou station 58027） were selected as controlled objects to carry out quality control using the AI method. Compared with IDW and the spatial regression test（SRT） in discriminating artificial errors, it is shown that the proposed method can mark suspicious data effectively. Furthermore, it is highly effective, stable, adaptable, and applicable in both plain and hilly areas.
