초록
본 연구에서는 한국 기온자료에 적용할 품질검정 알고리즘을 개발하고 알고리즘에 적용되는 기준값 및 기준값 도출 방법을 제시하였다. 이렇게 개발된 알고리즘을 부산 기상관측지점에 적용하여 검증하였고 그 검증결과를 제시하였다. 부산 기상관측지점은 극한값 검사와 기후범위 검사에서는 오류와 의심자료가 검출되지 않았고, 내적일치성 검사와 공간분포 검사에서 오류 및 의심자료가 검출되었다. 본 연구의 기온자료 품질검정 알고리즘은 구조적으로 명백한 오류자료 뿐만 아니라 자료의 시·공간적인 비교를 통해 잠재적 오류 의심자료를 분석자에게 제시하는 장점이 있다.
Abstract
In this study, the algorithms for quality control of station temperature data in Korea are developed and the thresholds for algorithms are suggested. The temperature data in Busan weather station is used for the application of the algorithms. From the results, neither errors nor suspicious value has been found from the high-low extreme check and temporal outliers check. However, the internal check and spatial outliers check have detected some errors. The quality control algorithms which are developed from this study provide potential errors as well as obvious errors in data analysis through spatio-temporal comparisons.
