High-Resolution Characterization Of A Semiarid Watershed: Implications On Evapotranspiration Estimates
Templeton, R. C., Vivoni, E. R., Méndez-Barroso, L. A., Pierini, N. A., Anderson, C. A., Rango, A., Laliberte, A. S., Scott, R. L.

The North American monsoon (NAM) contributes roughly half of the annual precipitation in the Chihuahuan Desert from July to September. Relatively frequent, intense storms increase soil moisture and lead to ephemeral runoff. Quantifying these processes, however, is difficult due to the sparse nature of existing observations. This …

Species-specific transpiration responses to intermediate disturbance in a northern hardwood forest
Matheny, A.M. Bohrer, G. Vogel, C.S. Morin, T.H. He, L. Frasson, R.P.dM. Mirfenderesgi, G. Schäfer, K.V.R. Gough, C.M. Ivanov, V.Y. Curtis, P.S.

Intermediate disturbances shape forest structure and composition, which may in turn alter carbon, nitrogen, and water cycling. We used a large-scale experiment in a forest in northern lower Michigan where we prescribed an intermediate disturbance by stem girdling all canopy-dominant early successional trees to simulate an accelerated …

Role Of Surface Energy Exchange For Simulating Wind Turbine Inflow: A Case Study In The Southern Great Plains, Usa
Wharton, S., Simpson, M., Osuna, J., Newman, J., Biraud, S.

he Weather Research and Forecasting (WRF) model is used to investigate choice of land surface model (LSM) on the near surface wind profile, including heights reached by multi-megawatt (MW) wind turbines. Simulations of wind profiles and surface energy fluxes were made using five LSMs of varying degrees of sophistication in dealing …

Long-Term Variability In The Water Budget And Its Controls In An Oak-Dominated Temperate Forest
Xie, J., Sun, G., Chu, H., Liu, J., McNulty, S. G., Noormets, A., John, R., Ouyang, Z., Zha, T., Li, H., Guan, W., Chen, J.

Water availability is one of the key environmental factors that control ecosystem functions in temperate forests. Changing climate is likely to alter the ecohydrology and other ecosystem processes, which affect forest structures and functions. We constructed a multi-year water budget (2004–2010) and quantified environmental controls …

Climate Change And Fire Management In The Mid-Atlantic Region
Clark, K. L., Skowronski, N., Renninger, H., Scheller, R.

In this review, we summarize the potential impacts of climate change on wildfire activity in the mid-Atlantic region, and then consider how the beneficial uses of prescribed fire could conflict with mitigation needs for climate change, focusing on patters of carbon (C) sequestration by forests in the region. We use a synthesis of …

Agricultural peatland restoration: effects of land-use change on greenhouse gas (CO2 and CH4) fluxes in the Sacramento-San Joaquin Delta
Knox, S. H.,, Sturtevant, C., Matthes, J.H., Koteen, L., Verfaillie,J., Baldocchi. D.

Agricultural drainage of organic soils has resulted in vast soil subsidence and contributed to increased atmospheric carbon dioxide (CO2) concentrations. The Sacramento-San Joaquin Delta in California was drained over a century ago for agriculture and human settlement and has since experienced subsidence rates that are among the …

Effects Of Fine-Scale Soil Moisture And Canopy Heterogeneity On Energy And Water Fluxes In A Northern Temperate Mixed Forest

Environmental drivers of methane fluxes from an urban temperate wetland park
Morin, T.H. Bohrer, G. Frasson, R.P.dM. Naor-Azrieli, L. Mesi, S. Stefanik, K.C. Schäfer, K.V.R.

Methane (CH4) emissions were measured at the Wilma H. Schiermeier Olentangy River Wetland Research Park (ORWRP) over three summers and two winters using an eddy covariance system. We used an empirical model to determine the main environmental drivers of methane emissions. Methane emissions covary strongly with water vapor fluxes, …

Biases In Regional Carbon Budgets From Covariation Of Surface Fluxes And Weather In Transport Model Inversions
Williams, I. N., Riley, W. J., Torn, M. S., Biraud, S. C., Fischer, M. L.

Recent advances in atmospheric transport model inversions could significantly reduce uncertainties in land carbon uptake through the assimilation of CO2 concentration measurements at weekly and shorter timescales. The potential of these measurements for reducing biases in estimated land carbon sinks depends on the strength of covariation …
