Drainage flow affects the eddy covariance CO2 fluxes on the forest hill slope of the Gwangneung KoFlux sites. The CO2 drainage is identified using an information flow dynamical process network (DPN). Based on the DPN, a site-specific filter was developed to eliminate the drainage-affected data. An information flow filter reduces discrepancies among the different nighttime flux corrections.
