Analysis Of Nitrogen Controls On Carbon And Water Exchanges In A Conifer Forest Using The CLASS-CTEMN+ Model
Huang, S., Arain, M. A., Arora, V. K., Yuan, F., Brodeur, J., Peichl, M.

A carbon (C) and nitrogen (N) cycle-coupled model, CLASS-CTEMN+ was developed by incorporating soil and plant N cycling algorithms in the Canadian Land Surface Scheme (CLASS) and the Canadian Terrestrial Ecosystem Model (CTEM), used in the Canadian Global …

Interpreting CO2 Fluxes Over A Suburban Lawn: The Influence Of Traffic Emissions
Hiller, R. V., McFadden, J. P., Kljun, N.

Turf-grass lawns are ubiquitous in the United States. However direct measurements of land–atmosphere fluxes using the eddy-covariance method above lawn ecosystems are challenging due to the typically small dimensions of lawns and the heterogeneity of land use in an urbanised landscape. Given their typically small patch sizes, there …

Three-Dimensional Canopy Fuel Loading Predicted Using Upward And Downward Sensing LiDAR Systems
Skowronski, N. S., Clark, K. L., Duveneck, M., Hom, J.

We calibrated upward sensing profiling and downward sensing scanning LiDAR systems to estimates of canopy fuel loading developed from field plots and allometric equations, and then used the LiDAR datasets to predict canopy bulk density (CBD) and crown fuel weight (CFW) in wildfire prone stands in the New Jersey Pinelands. …

Disturbance And The Resilience Of Coupled Carbon And Nitrogen Cycling In A North Temperate Forest
Nave, L.E., Gough, C.M., Maurer, K.D., Bohrer, G, Hardiman, B.S., Le Moine, J., Munoz, A.B., Nadelhoffer, K.J., Sparks, J.P., Strahm, B.D., Vogel, C.S., Curtis, P.S.

Much of our biogeochemical understanding of forest disturbances comes from studies of severe or stand-replacing events, which may have different impacts on coupled carbon (C) and nitrogen (N) cycling than …

Wildfire Reduces Carbon Dioxide Efflux And Increases Methane Uptake In Ponderosa Pine Forest Soils Of The Southwestern USA
Sullivan, B. W., Kolb, T. E., Hart, S. C., Kaye, J. P., Hungate, B. A., Dore, S., Montes-Helu, M.

Severe wildfire may cause long-term changes in the soil-atmosphere exchange of carbon dioxide and methane, two gases known to force atmospheric warming. We examined the effect of a severe wildfire 10 years after burning to determine decadal-scale changes in soil gas fluxes following fire, and explored mechanisms responsible for …

Seasonal Pattern Of Regional Carbon Balance In The Central Rocky Mountains From Surface And Airborne Measurements
Desai, A.R., Moore, D.J.P., Ahue, W.K.M., Wilkes, P.T.V., De Wekker, S.F.J., Brooks, B.G., Campos, T.L., Stephens, B.B., Monson, R.K., Burns, S.P., Quaife, T., Aulenbach, S.M., Schimel, D.S.

High-elevation forests represent a large fraction of potential carbon uptake in North America, but this uptake is not well constrained by observations. Additionally, forests in the Rocky Mountains have recently been severely damaged by drought, fire, and insect outbreaks, which have been quantified at local scales but not assessed …

Large Greenhouse Gas Emissions From A Temperate Peatland Pasture
Teh, Y. A., Silver, W. L., Sonnentag, O., Detto, M., Kelly, M., Baldocchi, D. D.

Agricultural drainage is thought to alter greenhouse gas emissions from temperate peatlands, with CH4 emissions reduced in favor of greater CO2 losses. Attention has largely focussed on C trace gases, and less is known about the impacts …

The Influence Of Carbon Exchange Of A Large Lake On Regional Tracer-Transport Inversions: Results From Lake Superior
Vasys, V. N., Desai, A. R., McKinley, G. A., Bennington, V., Michalak, A. M., Andrews, A. E.

Large lakes may constitute a significant component of regional surface–atmosphere fluxes, but few efforts have been made to quantify these fluxes. Tracer-transport inverse models that infer the CO2 flux from the atmospheric concentration typically assume that the influence from large lakes is negligible. CO2

Comparing Laser-Based Open- And Closed-Path Gas Analyzers To Measure Methane Fluxes Using The Eddy Covariance Method
Detto, M., Verfaillie, J., Anderson, F., Xu, L., Baldocchi, D.

Closed- and open-path methane gas analyzers are used in eddy covariance systems to compare three potential methane emitting ecosystems in the Sacramento-San Joaquin Delta (CA, USA): a rice field, a peatland pasture and a restored wetland. The study points out similarities …

Light-Stress Avoidance Mechanisms In A Sphagnum-Dominated Wet Coastal Arctic Tundra Ecosystem In Alaska
Zona, D., Oechel, W. C., Richards, J. H., Hastings, S., Kopetz, I., Ikawa, H., Oberbauer, S.

The Arctic experiences a high-radiation environment in the summer with 24-hour daylight for more than two months. Damage to plants and ecosystem metabolism can be muted by overcast conditions common in much of the Arctic. However, with climate change, extreme dry years and clearer skies could lead to the risk of increased photoxidation …
