Relationship between soil CO2 concentrations and forest-floor CO2 effluxes
Abstract To better understand the biotic and abiotic factors that control soil CO 2 efflux, we compared seasonal and diurnal variations in simultaneously measured forest-floor CO 2 effluxes and soilExpand

Spatial distribution of carbon sources and sinks in Canada’s forests
Annual spatial distributions of carbon sources and sinks in Canada’s forests at 1 km resolution are computed for the period from 1901 to 1998 using ecosystem models that integrate remote sensingExpand

Radiative forcing of natural forest disturbances
Forest disturbances are major sources of carbon dioxide to the atmosphere, and therefore impact global climate. Biogeophysical attributes, such as surface albedo (reflectivity), further control theExpand

Global comparison of light use efficiency models for simulating terrestrial vegetation gross primary production based on the LaThuile database
a b s t r a c t Simulating gross primary productivity (GPP) of terrestrial ecosystems has been a major challenge in quantifying the global carbon cycle. Many different light use efficiency (LUE)Expand

Instrumentation and approach for unattended year round tower based measurements of spectral reflectance
Abstract Phyto-pigments play an important role in plant physiological processes and primary production. Because different groups of pigments absorb light in distinctive ways, spectroscopy can be usedExpand

Estimating nocturnal ecosystem respiration from the vertical turbulent flux and change in storage of CO2
Micrometeorological measurements of nighttime ecosystem respiration can be systematically biased when stable atmospheric conditions lead to drainage flows associated with decoupling of air flow aboveExpand

Characterizing the diurnal patterns of errors in the prediction of evapotranspiration by several land‐surface models: An NACP analysis
Land-surface models use different formulations of stomatal conductance and plant hydraulics, and it is unclear which type of model best matches the observed surface-atmosphere water flux. We use theExpand

Annual greenhouse gas budget for a bog ecosystem undergoing restoration by rewetting
Abstract. Many peatlands have been drained and harvested for peat mining, agriculture, and other purposes, which has turned them from carbon (C) sinks into C emitters. Rewetting of disturbedExpand

Nocturnal mixing in a forest subcanopy
The vertical structure of the flow in the old aspen canopy in BOREAS is examined in terms of thermocouple profiles and sonic anemometers above, within, and below the aspen canopy. The data areExpand
