The standardized eddy covariance flux data processing in KoFlux has been updated, and its database has been amended accordingly. KoFlux data users have not been informed properly regarding these changes and the likely impacts on their analyses. In this paper, we have documented how the current struc...

국내 플럭스 관측망이란? | 국내 플럭스 관측망(Korea Flux Monitoring Network,KoFlux)은 2002년 1월 공식 출범한 이후 에디 공분산 시스템으로 관측된 플럭스 자료의 처리와 개선에 관련된 논문을 지속적으로 발표해왔다. Hong and Kim(2002)은 방대한 플럭스 관측 자료를 효율적이고, 일괄적으로 처리할 수 있는 초기 KoFlux 프로그램을 구축, 문서화하였다. | |
자료사용자들이 Flux 자료를 이용할 때 주의할 점은? | 자료 처리 방법과 과정이 갱신되면 이에 따라 그 결과도 달라지게되는데, 자료 사용자들은 자료 처리 결과의 차이와 이러한 차이가 자신들의 분석 결과에 미칠 수 있는 영향에 대해 제대로 인지하지 못하고 있는 실정이다. 자료사용자는 자료의 갱신 여부를 확인하고, 자료 처리 방법 및 처리 과정의 변화에 따른 값의 차이를 감안하여신중하게 자료를 사용하여야 한다. | |
KoFlux의 에디 공분산 자료 처리 과정을 ChinaFlux, JapanFlux와 비교한 결과는? | ,2013). 그 결과, 플럭스 값의 전반적인 계절변동은 유사하게 나타났지만, 비생장기간에 관측된 음의 순생태계교환량의 처리(제거 여부)에 따라 상당한 차이가 발생됨을 확인하였다. 이러한 상호 비교의 노력을 통해 자료 처리 과정에 따른 불확도는 어느 정도 평가되었지만, AsiaFlux가 일반적으로 공유할 수 있는 표준화된 자료 처리 방법은 아직까지 도출되지 않았으며, 각 관측망 별로 상황에 특화된 자료 처리 방법을 사용하고 있는 실정이다. |
