Modeling Energy And Carbon Fluxes In A Heterogeneous Oak Woodland: A Three-Dimensional Approach
Kobayashi, H., Baldocchi, D. D., Ryu, Y., Chen, Q., Ma, S., Osuna, J. L., Ustin, S. L.

Most land surface and ecosystem models assume that a vegetated canopy can be abstracted as a turbid medium when such models compute mass, energy, and carbon exchange. However, those models fail to simulate radiation environments in heterogeneous landscapes. This study aims to couple a spatially explicit three-dimensional (3D) shortwave …

Carbon Dioxide Exchange Over Multiple Temporal Scales In An Arid Shrub Ecosystem Near La Paz, Baja California Sur, Mexico
Bell, T. W., Menzer, O., Troyo-Diéquez, E., Oechel, W. C.

Arid environments represent 30% of the global terrestrial surface, but are largely under-represented in studies of ecosystem carbon flux. Less than 2% of all FLUXNET eddy covariance sites exist in a hot desert climate. Long-term datasets of these regions are vital for capturing the seasonal and interannual variability that occur …

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 …

Improving Canopy Processes In The Community Land Model Version 4 (CLM4) Using Global Flux Fields Empirically Inferred From FLUXNET Data
Bonan, G.B., Lawrence, P.J., Oleson, K.W., Levis, S., Jung, M., Reichstein, M., Lawrence, D.M., Swenson, S.C.

The Community Land Model version 4 (CLM4) overestimates gross primary production (GPP) compared with data-driven estimates and other process models. We use global, spatially gridded GPP and latent heat flux …

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 …

Are Temporal Variations Of Leaf Traits Responsible For Seasonal And Inter-Annual Variability In Ecosystem CO2 Exchange?
Ma, S., Baldocchi, D. D., Mambelli, S., Dawson, T. E.
  1.  Seasonal and inter-annual variability in ecosystem carbon dioxide (CO2) exchange is attributed to numerous climate drivers. However, climate effects on metabolism often override ecological functions. This study seeks insight into which biological and ecological processes influence temporal patterns of ecosystem …
