USING AIRBORNE LIDAR FOR THE ASSESSMENT OF CANOPY STRUCTURE INFLUENCES ON CO2 FLUXES
airborne lidar carbon dioxide eddy covariance flux footprint canopy structure photosynthesis respiration
2015/11/10
Fluxes of carbon dioxide (CO2), water, and energy measured using the eddy covariance method (EC) will vary spatially and temporally within the catchment area of the EC system, especially if parts of t...
Soil surface CO2 fluxes in a Norway spruce stand
Norway spruce Picea abies soil CO2 efflux Q10
2015/2/2
The measurements of soil CO2 efflux in a Norway spruce (Picea abies [L.] Karst.) forest stand are reported for a 6-month period (from May 1st to October 26th 1999). Forest floor CO2 efflux was measure...
Variability of Air-Sea CO2 Fluxes and Dissolved Inorganic Carbon Distribution in the Atlantic Basin: A Coupled Model Analysis
Carbon Cycle Atlantic Basin Coupled Model Climatological Analysis
2013/3/11
The biogeochemical dynamics of carbon in the ocean is a subject of fundamental interest to environmental studies. In this context, we have implemented a ten year run of the Brazilian Earth System Coup...
Regional-scale geostatistical inverse modeling of North American CO2 fluxes: a synthetic data study
Regional-scale geostatistical North American CO2 fluxes a synthetic data study
2010/8/16
A series of synthetic data experiments is performed to investigate the ability of a regional atmospheric inversion to estimate grid-scale CO2 fluxes during the growing season over North America. The i...
Seasonal and diurnal variations in moisture, heat and CO2 fluxes over a typical steppe prairie in Inner Mongolia, China
moisture CO2 fluxes heat
2009/7/22
In order to examine energy partitioning and CO2 exchange over a steppe prairie in Inner Mongolia, China, fluxes of moisture, heat and CO2 in the surface layer from June 2007 through June 2008 were cal...
Estimating surface CO2 fluxes from space-borne CO2 dry air mole fraction observations using an ensemble Kalman Filter
surface CO2 fluxes space-borne CO2 ensemble Kalman Filter
2009/5/6
We have developed an ensemble Kalman Filter (EnKF) to estimate 8-day regional surface fluxes of CO2 from space-borne CO2 dry-air mole fraction observations (XCO2) and evaluate the approach using a ser...
On using radon-222 and CO2 to calculate regional-scale CO2 fluxes
radon-222 CO2 regional-scale CO2
2008/12/15
Because of its ubiquitous release on land and well-characterized atmospheric loss, radon-222 has been very useful for deducing fluxes of greenhouse gases such as CO2, CH4, and N2O. It is shown here th...
Multiple quality tests for analysing CO2 fluxes in a beech temperate forest
Multiple quality tests CO2 fluxes beech temperate forest
2010/1/15
Eddy covariance (EC) measurements are widely used to estimate the amount of carbon sequestrated by terrestrial biomes. The decision to exclude an EC flux from a database (bad quality records, turbulen...
The Integrated Environmental Monitoring (IEM) project, part of the Asia-Pacific Environmental Innovation Strategy (APEIS) project, developed an integrated environmental monitoring system t...
Effects of climate warming and declining species richness in grassland model ecosystems:acclimation of CO2 fluxes
climate warming declining species richness grassland model ecosystems CO2 fluxes
2010/1/14
To study the effects of warming and declining species richness on the carbon balance of grassland communities, model ecosystems containing one, three or nine species were exposed to ambient and elevat...
Controls over N2O,NOx and CO2 fluxes in a calcareous mountain forest soil
Controls N2O NOx CO2 fluxes calcareous mountain forest soil
2010/1/13
We measured nitrogen oxides (N2O and NOx), dinitrogen (N2) and carbon dioxide (CO2) emissions from a spruce-fir-beech forest soil in the North Tyrolean limestone Alps in Austria. The site received 10....
Whole-system metabolism and CO2 fluxes in a Mediterranean Bay dominated by seagrass beds (Palma Bay,NW Mediterranean)
Whole-system metabolism CO2 fluxes Mediterranean Bay seagrass beds
2010/1/12
Planktonic and benthic incubations (bare and Posidonia oceanica vegetated sediments) were performed at monthly intervals from March 2001 to October 2002 in a seagrass vegetated area of the Bay of Palm...
