基于CIMISS的土壤水分质控应用研究

气象资料业务系统MDOS(meteorological data operation system)的质控方法使用通用阈值去质控土壤水分数据,会漏检和误检出部分疑误数据,且疑误结果多以"未通过降水关系检查"为主,降低值班人员的数据审核效率.为了提高土壤水分质控效率,结合本地土壤特性,分析海南土壤水分历史数据,总结适合本...

Application Research of Quality Control of Soil Moisture Based on CIMISS

The general threshold is used in the quality control methods of MDOS(meteorological data operation system)to control soil moisture data so that some suspected data are missed and detected by mistake and most of suspected result are mainly failing the inspection of precipitation relationship which leads to data audit by duty staff with lower efficiency.The suitable threshold range parameters are summarized by considering local soil characteristics and analyzing the historical data of soil moisture in Hainan.With introducing inspection methods such as time-varying and time-continuity,an algorithm of Multiple Quality Control of Soil Moisture based on China Integrated Meteorological Information Service System is proposed to discover suspected data of soil moisture quickly and accurately by multiple quality control and the result are classified and displayed in the web page for the screening of personnel on duty.Compared with the existing quality control methods,the result of business trial showed that suspected data of soil moisture were screened accurately and effectively through MQCSM algorithm and were displayed on the monitoring platform for improving the efficiency of data audit by personnel on duty.
