Regional Carbon Dioxide Fluxes From Mixing Ratio Data
Bakwin, P. S., Davis, K. J., Yi, C., Wofsy, S. C., Munger, J. W., Haszpra, L., Barcza, Z.

We examine the atmospheric budget of CO2 at temperate continental sites in the Northern Hemisphere. On a monthly time scale both surface exchange and atmospheric transport are important in determining the rate of change of CO2 mixing ratio at these sites. Vertical differences between the atmospheric boundary …

The Surface CO2 Gradient And Pore-Space Storage Flux In A High-Porosity Litter Layer
Hirsch, A. I., Trumbore, S. E., Goulden, M. L.


Journal: Tellus Series B-Chemical and Physical Meteorology, Volume 56 (4): 312-321 (2004). DOI: 10.1111/j.1600-0889.2004.00113.x Sites: CA-Man, CA-NS2, CA-NS3, CA-NS5, CA-NS6, CA-NS7

A Global Relationship Between The Heterotrophic And Autotrophic Components Of Soil Respiration?
Bond-Lamberty, B., Wang, C., Gower, S. T.

Soil surface CO2 flux (RS) is overwhelmingly the product of respiration by roots (autotrophic respiration, RA) and soil organisms (heterotrophic respiration, RH). Many studies have attempted to partition RS into these two components, with highly …

Carbon Distribution Of A Well- And Poorly-Drained Black Spruce Fire Chronosequence
Wang, C., Bond-Lamberty, B., Gower, S. T.

The objective of this study was to quantify carbon (C) distribution for boreal black spruce (Picea mariana (Mill.) BSP) stands comprising a fire chronosequence in northern Manitoba, Canada. The experimental design included seven well-drained (dry) and seven poorly-drained (wet) stands that burned between 1998 and 1850. Vegetation …

Leaf Area Dynamics Of A Boreal Black Spruce Fire Chronosequence
Bond-Lamberty, B., Wang, C., Gower, S. T., Norman, J.

Specific leaf area (SLA) and leaf area index (LAI) were estimated using site-specific allometric equations for a boreal black spruce (Picea mariana (Mill.) BSP) fire chronosequence in northern Manitoba, Canada. Stands ranged from 3 to 131 years in age and had soils that were categorized as well or poorly drained. The goals …

Similarity Theory For Local And Spatially Averaged Momentum Fluxes
Nakamura, R., Mahrt, L.

Tower and aircraft data from a number of field studies are analyzed to: (1) estimate the roughness lengths for local and area-averaged momentum fluxes over various surface types; (2) examine the applicability of the ψ-stability formulations of Paulson and Dyer for momentum fluxes; (3) investigate the possibility …

Remote Sensing Of Photosynthetic-Light-Use Efficiency Of Boreal Forest
Nichol, C. J., Huemmrich, K. F., Black, T., Jarvis, P. G., Walthall, C. L., Grace, J., Hall, F. G.

Using a helicopter-mounted portable spectroradiometer and continuous eddy covariance data we were able to evaluate the photochemical reflectance index (PRI) as an indicator of canopy photosynthetic light-use efficiency (LUE) in four boreal forest species during the Boreal …

Water And Carbon Dioxide Exchange At A Boreal Young Jack Pine Forest In The BOREAS Northern Study Area
Joiner, D. W., McCaughey, J. H., Lafleur, P. M., Bartlett, P. A.

Climatological measurements, including carbon dioxide flux density, were made from May to September 1994 and from May to November 1996 at a young jack pine (Pinus banksiana Lamb.) forest near Thompson, …

Boreas Flight Measurements Of Forest-Fire Effects On Carbon Dioxide And Energy Fluxes
Amiro, B., MacPherson, J. I., Desjardins, R. L.

Fire is the dominant stand-replacing agent in the Canadian boreal forest, but few quantitative measurements are available on the micrometeorological effects of fire. Airborne flux measurements during the BOREAS experiment were referenced to age of burn along a 500-km transect …
