Abstract

Recently, as disasters caused by weather such as heavy rains have increased, interests in forecasting weather and disasters using radars have been increasing, and related studies have also been actively performed. As the Ministry of Environment(ME) has established and operated a radar network on a national scale, utilization of radars has been emphasized. However, persons in charge and researchers, who want to use the data from radars need to understand characteristics of the radar data and are also experiencing a lot of trials and errors when converting and calibrating the radar data from Universal Format(UF) files. Hence, this study developed a Radar Display and Analysis Program(RaDAP) based on Graphic User Interface(GUI) using the Java Programming Language in order for UF-type radar data to be generated in an ASCII-formatted image file and text file. The developed program can derive desired radar rainfall data and minimize the time required to perform its analysis. Therefore, it is expected that this program will contribute to enhancing the utilization of radar data in various fields.

최근 집중호우 등 기상으로 인한 재해가 증가함에 따라 수문기상, 방재분야에서 레이더를 이용한 기상 및 재해예측에 대한 관심이 증대되고 관련연구가 활발히 이루어지고 있다. 환경부 등에서는 레이더 네트워크를 전국적으로 구축 운영함에 따라 레이더의 활용성이 강조되고 있지만, 레이더자료를 활용하고자 하는 실무자 및 연구자들은 레이더자료의 특성을 이해해야하고 레이더자료 형식(UF)의 변환과 보정에 시행착오를 경험하고 있다. 이에 본 연구에서는 UF형식의 레이더자료를 이미지 및 텍스트파일(ASCII file)로 생성할 수 있도록 JAVA 언어를 이용한 GUI방식의 레이더자료를 표출 및 분석 프로그램(RaDAP; Radar Display and Analysis Program)을 개발하였다. 본 프로그램을 이용하여 원하는 레이더강우 자료를 도출하고 이를 이용한 분석을 수행하는데 필요한 소요시간을 최소화 할 수 있어 다양한 분야에서 레이더자료의 활용성을 높이는데 기여할 것으로 예상된다.
