Analysis of Correction Method on Eddy Flux Measurement over Complex Terrain

Abstract

Abstract: Based on the observation data of the flux measurement in the subtropical coniferious and broad-leafed mixed forest ecosystem in Dinghushan,the influence of the typical correction method on eddy flux estimates of carbon dioxide was analyzed.The main results were as follows: 1) By using all of the three coordinate system transforming methods of Double Rotation(DR),Triple Rotation(TR) and Planer Fit(PF),the absolute values of CO2 flux(Fc) after terrain correction tended to be smaller than uncorrected values.Sequence order of changed Fc extend was DR

Key words: Eddy covariance, Eddy covariance, Carbon flux, Dinghushan, Coniferious and broad-leaved forest.
