Correction of flux measurements for density effects due to heat and water vapour transfer
When the atmospheric turbulent flux of a minor constituent such as CO2 (or of water vapour as a special case) is measured by either the eddy covariance or the mean gradient technique, account mayExpand
A critical appraisal of a combined stomatal‐photosynthesis model for C3 plants
Gas-exchange measurements on Eucalyptus grandis leaves and data extracted from the literature were used to test a semi-empirical model of stomatal conductance for CO 2 , g sc = g 0 + a 1 /[(c s −Γ)(1Expand
Leaf nitrogen, photosynthesis, conductance and transpiration : scaling from leaves to canopies
A model is presented which solves simultaneously for leaf‐scale stomatal conductance, CO2 assimilation and the energy balance as a function of leaf position within canopies of well‐wateredExpand
Maximum conductances for evaporation from global vegetation types
We compare independent data sets of the maximum stomata1 conductance (gsmax, for single leaves) and bulk surface conductance (G,,,,, for a vegetated surface including the plant canopy and soil) forExpand
A Re-Evaluation of Long-Term Flux Measurement Techniques Part I: Averaging and Coordinate Rotation
Experience of long term flux measurements over tall canopiesduring the last two decades has revealed that the eddy flux of sensible plus latentheat is typically 30% smaller than the available radiantExpand
A coupled model of stomatal conductance, photosynthesis and transpiration
A model that couples stomatal conductance, photosynthesis, leaf energy balance and transport of water through the soil–plant–atmosphere continuum is presented. Stomatal conductance in the modelExpand
Relationships among Maximum Stomatal Conductance, Ecosystem Surface Conductance, Carbon Assimilation Rate, and Plant Nitrogen Nutrition: A Global Ecology Scaling Exercise
This review provides a theoretical framework and global maps for relations between nitrogen-(N)-nutrition and stomatal conductance, gs' at the leaf scale and flUXe!1 of water vapor and carbon dioxideExpand
Regional evaporation estimates from flux tower and MODIS satellite data
Abstract Two models were evaluated for their ability to estimate land surface evaporation at 16-day intervals using MODIS remote sensing data and surface meteorology as inputs. The first was theExpand
Reflections on the surface energy imbalance problem
The ‘energy imbalance problem’ in micrometeorology arises because at most flux measurement sites the sum of eddy fluxes of sensible and latent heat (H + λE) is less than the available energy (A).Expand
The propagation of errors in long‐term measurements of land‐atmosphere fluxes of carbon and water
For surface fluxes of carbon dioxide, the net daily flux is the sum of daytime and nighttime fluxes of approximately the same magnitude and opposite direction. The net flux is therefore significantlyExpand
