Quality Control of Agro meteorological Data Measured at Suwon Weather Station of Korea Meteorological Administration
In this research, we applied a procedure of quality control (QC) to the agro meteorological data measured at the Suwon weather station of Korea Meteorological Administration (KMA) The QC was conducted through six steps based on the KMA Real time Quality control system for Meteorological Observation Data (RQMOD) and four steps based on the International Soil Moisture Network (ISMN) QC modules. In addition, we set up our own empirical method to remove erroneous data which could not be filtered by the RQMOD and ISMN methods. After all these QC procedures, a well refined agro meteorological dataset was complied at both air and soil temperatures. Our research suggests that soil moisture requires more detailed and reliable grounds to remove doubtful data, especially in winter with its abnormal variations. The raw data and the data after QC are now available at the NCAM website (http:/ncam.kr/page/req/agri_weather.php)
