Eddy Covariance, Carbon Dynamics Monitoring

The eddy covariance technique ascertains the exchange rate of carbon dioxide (CO2) across the interface between the atmosphere and a plant canopy by measuring the covariance between fluctuations between vertical wind velocity and CO2 mixing ratio. Meteorological parameters were also measured for understanding the environmental conditions for ecosystem carbon cycle. To compare carbon balance of two contrasting tropical forests in Thailand, dry evergreen (DEF) and mixed deciduous (MDF) forests, net ecosystem exchange (NEE) was estimated and the choice of a friction velocity (u*) correction for the estimation of flux on calm night and other corrections were applied for data quality control. The change in NEE as a function of the u* threshold was marked, and some of the measured nocturnal data were eliminated by using the 0.4 and 0.25 m s
