ABSTRACT
Recently, the flux community in Korea established a new regional flux network, so-called KoFlux, which will provide an infrastructure for collecting, synthesizing, and analysing long-term measurements of energy and mass exchange between the atmosphere and the various vegetated surfaces. KoFlux requires the collection of long time series of raw data, and a large amount of data are expected to accumulate due to continuous flux observations at each KoFlux sites. Therefore, we need a systematic and efficient tool to manage these raw data. As a part of this effort, a computer program far processing raw data measured from micrometeorological field experiments was developed for the flux community in Korea. In this paper, we introduce this program for processing raw data to estimate fluxes and other turbulent statistics and explain the micrometeolological processes coded in this data-processing program. Also, we show some examples on how to run the program and handle the outputs for the unique purpose of research interest.

적요

국내외에 구축된 다양한 플럭스 관측소로부터 관측된 자료는 그 크기가 방대하다. 따라서 이렇게 저장된 막대한 양의 자료를 처리하여, 원하는 정보를 얻어내는 것은 기술적으로 쉬운 일이 아니다. 그리고 자료처리는 연구 목적에 따라 다양한 형태의 자료 처리를 되도록 쉽게 처리하여 비교할 수 있어야 한다. 이에 따라 자료가 저장된 파일서버로부터 자료를 직접 읽어서, 필요한 자료를 보다 효율적이며, 일괄적으로 처리하는 프로그램을 개발하였다. 이 프로그램은 FORTRAN90과 CPP를 이용하여 만들어졌으며, 지면과 대기 사이에 교환되는 물질과 에너지를 정량화하는데 필요한 보정 과정과 품질 검증을 위한 과정을 포함하고 있다. 새로운 물리 과정과 보정 방법을 프로그램화하고, 간편하게 자료를 처리할 수 있도록 프로그램은 계속 보완 수정되어 나가야 한다.
