A real-time quality control system for meteorological data (air temperature, airpressure, relative humidity, wind speed, wind direction, and precipitation) measured by an integratedmeteorological sensor has been developed based on comparison of quality control proceduresfor meteorological data that were developed by the World Meteorological Organizationand the Korea Meteorological Administration (KMA), using time series and statistical analysisof a 12-year meteorological data set observed from 2000 to 2011 at the Incheon site in Korea. The quality control system includes missing value, physical limit, step, internal consistency,persistence, and climate range tests. Flags indicating good, doubtful, erroneous, not checked, ormissing values were added to the raw data after the quality control procedure. The climaterange test was applied to the monthly data for air temperature and pressure, and its thresholdvalues were modified from ± 2 σ and ± 3 σ to ± 3 σ and ± 6 σ, respectively, in order to considerextreme phenomena such as heat waves and typhoons. In addition, the threshold values ofthe step test for air temperature, air pressure, relative humidity, and wind speed were modifiedto 0.7oC, 0.4 hPa, 5.9%, and 4.6 m s−1, respectively, through standard deviation analysis of stepdifference according to their averaging period. The modified quality control system wasapplied to the meteorological data observed by the Weather Information Service Engine inMarch 2014 and exhibited improved performance compared to the KMA procedures.
Abstract
A real-time quality control system for meteorological data (air temperature, airpressure, relative humidity, wind speed, wind direction, and precipitation) measured by an integratedmeteorological sensor has been developed based on comparison of quality control proceduresfor meteorological data that were developed by the World Meteorological Organizationand the Korea Meteorological Administration (KMA), using time series and statistical analysisof a 12-year meteorological data set observed from 2000 to 2011 at the Incheon site in Korea. The quality control system includes missing value, physical limit, step, internal consistency,persistence, and climate range tests. Flags indicating good, doubtful, erroneous, not checked, ormissing values were added to the raw data after the quality control procedure. The climaterange test was applied to the monthly data for air temperature and pressure, and its thresholdvalues were modified from ± 2 σ and ± 3 σ to ± 3 σ and ± 6 σ, respectively, in order to considerextreme phenomena such as heat waves and typhoons.
