Airborne Laser Scanner-Assisted Estimation Of Aboveground Biomass Change In A Temperate Oak–Pine Forest
Skowronski, N. S., Clark, K. L., Gallagher, M., Birdsey, R. A., Hom, J. L.

We estimated aboveground tree biomass and change in aboveground tree biomass using repeated airborne laser scanner (ALS) acquisitions and temporally coincident ground observations of forest biomass, for a relatively undisturbed period (2004–2007; ∆07–04), a contrasting period of disturbance (2007–2009; ∆09–07), …

Influence And Predictive Capacity Of Climate Anomalies On Daily To Decadal Extremes In Canopy Photosynthesis
Desai, A. R.

Significant advances have been made over the past decades in capabilities to simulate diurnal and seasonal variation of leaf-level and canopy-scale photosynthesis in temperate and boreal forests. However, long-term prediction of future forest productivity …

Hot Spots, Hot Moments, And Spatio-Temporal Controls On Soil Co2 Efflux In A Water-Limited Ecosystem
Leon, E., Vargas, R., Bullock, S., Lopez, E., Panosso, A. R., La Scala, N.

Soil CO2 efflux is the primary source of CO2 emissions from terrestrial ecosystems to the atmosphere. The rates of this flux vary in time and space producing hot moments (sudden temporal high fluxes) and hot spots (spatially defined high fluxes), but these high reaction rates are rarely studied in conjunction with each other. We …

The Spatial Scale Dependence Of Water Vapor Variability Inferred From Observations From A Very Tall Tower
Pressel, K. G., Collins, W. D., Desai, A. R.

Recent studies have established that atmospheric water vapor fields exhibit spatial spectra that take the form of power laws and hence can be compactly characterized by scaling exponents. The power law scaling exponents have been shown to exhibit substantial vertical variability. In this work, Taylor’s frozen turbulence hypothesis …

Parsing The Variability In Ch4 flux At A Spatially Heterogeneous Wetland: Integrating Multiple Eddy Covariance Towers With High-Resolution Flux Footprint Analysis
Matthes, J. H., Sturtevant, C., Verfaillie, J., Knox, S., Baldocchi, D.

Restored wetlands are a complex mosaic of open water and new and old emergent vegetation
patches, where multiple environmental and biological drivers contribute to the measured heterogeneity in
methane (CH4) flux. In this analysis, we replicated the measurements of CH4 flux using the eddy covariance
technique at three tower locations …

Snow Temperature Changes Within A Seasonal Snowpack And Their Relationship To Turbulent Fluxes Of Sensible And Latent Heat
Burns, S. P., Molotch, N. P., Williams, M. W., Knowles, J. F., Seok, B., Monson, R. K., Turnipseed, A. A., Blanken, P. D.

Snowpack temperatures from a subalpine forest below Niwot Ridge, Colorado, are examined with respect to atmospheric conditions and the 30-min above-canopy and subcanopy eddy covariance fluxes of sensible Qh and latent Qe heat. In the lower snowpack, daily snow temperature changes greater than 1°C day−1 occurred about 1–2 times …

Growing season eddy covariance measurements of carbonyl sulfide and CO2 fluxes: COS and CO2 relationships in Southern Great Plains winter wheat
Billesbach,D.P., Berry,J.A., Seibt,U., Maseyk,K., Torn,M.S., Fischer,M.L., Abu-Naserg,M., Campbell,J.E.

To test the capabilities of newly available instrumentation and to explore the dynamics of carbonyl sulfide(COS) as a proxy for the measurement of canopy-scale gross primary production (GPP), we conducted an experiment to measure the simultaneous net transfer of COS and CO2 between the atmosphere and a growing wheat canopy, senesced …
