We analyzed half-hourly tower-based flux measurements of carbon dioxide (CO 2 ) from a boreal aspen forest and a temperate mixed deciduous forest in Canada to examine the influences of clouds on forest carbon uptake. We showed that the presence of clouds consistently and significantly increased the net ecosystem exchanges (NEE) of CO 2 of both forests from the level under clear skies. The enhancement varied with cloudiness, solar elevation angles, and differed between the two forests. For the… 

Impact of cloudiness on net ecosystem exchange of carbon dioxide in different types of forest ecosystems in China

Clouds can significantly affect carbon exchange process between forest ecosystems and the atmosphere by influencing the quantity and quality of solar radiation re- ceived by ecosystem's surface and

On the relationship between cloudiness and net ecosystem carbon dioxide exchange in a peatland ecosystem

ABSTRACT The relationship between incident light intensity and net ecosystem CO2 exchange (NEE) was examined at a low-shrub bog located near Ottawa, Canada. Shrub height was 0.25 m and maximum leaf

Comparing the impact of cloudiness on carbon dioxide exchange in a grassland and a maize cropland in northwestern China

Light quantity and quality strongly influence plant growth. However, different ecosystems have different capabilities to assimilate solar radiation. In this study, the effects of cloudiness intensity

The effects of clouds and aerosols on net ecosystem CO 2 exchange over semi-arid Loess Plateau of Northwest China

Abstract. The impacts of clouds and atmospheric aerosols on the terrestrial carbon cycle at semi-arid Loess Plateau in Northwest China are investigated, by using the observation data obtained at the

Factors controlling CO2 exchange in a middle latitude forest

[1] The forest carbon uptake experiences a relatively steady state, in which both radiation use efficiency and Bowen ratio exhibit relatively small change in tendency during the middle growing season

Cloud shading and fog drip influence the metabolism of a coastal pine ecosystem

It is concluded that clouds are important to the ecological functioning of these coastal forests, providing summer shading and cooling that relieve pine and microbial drought stress as well as regular moisture inputs that elevate plant and microbial metabolism.

Variability of Carbon and Water Fluxes Following Climate Extremes over a Tropical Forest in Southwestern Amazonia

The carbon and water cycles for a southwestern Amazonian forest site were investigated using the longest time series of fluxes of CO2 and water vapor ever reported for this site, found to have a net carbon uptake of ≈5 t C ha−1 year−1, but the effects of the drought of 2005 were still noticed in 2006, when the climate disturbance caused the site to become a net source of carbon to the atmosphere.

Ecophysiological controls over the net ecosystem exchange of mountain spruce stand. Comparison of the response in direct vs. diffuse solar radiation

Cloud cover increases the proportion of diffuse radiation reaching the Earth's surface and affects many microclimatic factors such as temperature, vapour pressure deficit and precipitation. We

Cloudy Sky Conditions Promote Net Ecosystem CO2 Exchange in a Subtropical Coniferous Plantation Across Seasons

Abstract: Dynamic changes in solar radiation have an important influence on ecosystem carbon sequestration, but the effects of changes caused by sky conditions on net ecosystem CO2 exchange (NEE) are

Measuring and modelling carbon dioxide and water vapour exchange over a temperate broad‐leaved forest during the 1995 summer drought

Forests in the south-eastern United States experienced a prolonged dry spell and above-normal temperatures during the 1995 growing season. During this episode, nearly continuous, eddy covariance

Carbon dioxide exchange between an undisturbed old-growth temperate forest and the atmosphere

Ecosystem COZ uptake was enhanced by diffuse PPFD, a result of potentially global significance given recent increases in Northern Hemisphere haze, and a new result has implications for the development of models for diurnal ecosystem CO, exchange.

Net Exchange of CO2 in a Mid-Latitude Forest

The eddy correlation method was used to measure the net ecosystem exchange of carbon dioxide continuously from April 1990 to December 1991 in a deciduous forest in central Massachusetts, and carbon uptake rates were notably larger than those assumed for temperate forests in global carbon studies.

Long‐term observation of the atmospheric exchange of CO2 with a temperate deciduous forest in southern Ontario, Canada

This paper reports the results of the analysis of eddy covariance CO2 data obtained at a successional forest of maple and aspen at Camp Borden in southern Ontario, Canada, between July 1995 and

We used eddy covariance to measure the net exchange of CO2 between the atmosphere and a black spruce (Picea mariana) forest in Manitoba for 16,500 hours from March 16, 1994 to October 31, 1996. We

Abstract The primary objective of this study was to understand the environmental and seasonal controls over isoprene emissions from a boreal forest ecosystem whose isoprene source came from trees of

A study of weekly samples from a global network of 43 sites defined the latitudinal and temporal patterns of the two carbon sinks and identified those processes that would cause the terrestrial biosphere to absorb carbon dioxide in such large quantities.
