For this, energy balance closure represents a power- ful test for eddy flux measurements since it may allow the experimental data set to be validated on a mean basis, but also the
Heat balance components for eight measurement periods (81 days) were used in the comparison. There was good agreement between model simulations and measurements. The average
The vertical distribution of sources and sinks within the canopy is derived from direct measurements of both the NH 3 concentration profile and the turbulence within the canopy,
Source distributions for heat, water vapour, CO2 and CH4 within a rice canopy were derived using measured concentration profiles, a prescribed turbulence field and an inverse
The total soil evaporation was greater in Low N than High N treatments since the portion of the soil surface exposed to sunlight during wetting periods was somewhat larger in Low
For example, using eddy covari- ance measurements, Tsukamoto (1993) found a sig- nificantly smaller net CO 2 flux from the atmosphere to a rice canopy when the field was drained
The turbu- lent exchange coefficient was calculated using sur- face layer flux–gradient relationships and the fluxes of heat and momentum measured by the eddy covari- ance method..
Based on our measurements, the major factors that affected carbon uptake in this ecosystem were (a) the timing of new leaf development, (b) the severity of seasonal drought
