Biophysical Drivers Of Net Ecosystem And Methane Exchange Across Phenological Phases In A Tidal Salt Marsh
Vázquez-Lule, A., Vargas, R.

Salt marshes are large carbon reservoirs as part of blue carbon ecosystems. Unfortunately, there is limited information about the net ecosystem (NEE) and methane (CH4) exchange between salt marshes and the atmosphere to fully understand their carbon dynamics. We tested the influence of biophysical drivers by plant phenological phases …

Ecosystem‐Atmosphere Exchange Of CO2, Water, And Energy In A Basin Mangrove Of The Northeastern Coast Of The Yucatan Peninsula
Alvarado‐Barrientos, M. S., López‐Adame, H., Lazcano‐Hernández, H. E., Arellano‐Verdejo, J., Hernández‐Arana, H. A.

Coastal settings variations are linked to composition, structural, and functional differences among mangrove ecotypes. Basin mangroves undergo larger flooding and salinity fluctuations, yet remain understudied, compared to other ecotypes. We evaluated the effect of flooding and air temperature (T a) on the surface energy balance …

Temporal Trends In Methane Emissions From A Small Eutrophic Reservoir: The Key Role Of A Spring Burst
Waldo, S., Beaulieu, J. J., Barnett, W., Balz, D. A., Vanni, M. J., Williamson, T., Walker, J. T.

Waters impounded behind dams (i.e., reservoirs) are important sources of greenhouses gases (GHGs), especially methane (CH4), but emission estimates are not well constrained due to high spatial and temporal variability, limitations in monitoring methods to characterize hot spot and hot moment emissions, and the limited number of studies …

Linking Vegetation Spectral Reflectance With Ecosystem Carbon Phenology In A Temperate Salt Marsh
Hill, A. C., Vázquez-Lule, A., Vargas, R.

Salt marshes constitute an important terrestrial-aquatic interface that remains underrepresented in Earth System Models due to constraining biophysical controls and spatially limited land cover. One promising approach to improve representativeness is the application of proximal remote sensing to generate phenological information, …

Ebullition Dominates Methane Fluxes From The Water Surface Across Different Ecohydrological Patches In A Temperate Freshwater Marsh At The End Of The Growing Season
Villa, J. A., Ju, Y., Yazbeck, T., Waldo, S., Wrighton, K. C., Bohrer, G.

Measurements of the spatial heterogeneity of methane fluxes in wetlands are critical to better understand and predict methane emissions at the ecosystem scale. However, the within-wetland spatial heterogeneity of fluxes is rarely assessed. Here, we use a spatially balanced rapid chamber-based survey of methane at different ecohydrological …

Modeling Profiles Of Micrometeorological Variables In A Tropical Premontane Rainforest Using Multi‐Layered Clm (Clm‐Ml)
Song, J., Miller, G. R., Cahill, A. T., Aparecido, L. M., Moore, G. W.

This study updates the multi‐layered Community Land Model (CLM‐ml) for hillslopes and compares predictions from against observations collected in tropical montane rainforest, Costa Rica. Modifications are made in order to capture a wider array of vertical leaf area distributions, predict CO2 profiles, account for soil …

Assessing Forest Level Response To The Death Of A Dominant Tree Within A Premontane Tropical Rainforest
Flores III, M. R., Aparecido, L. M., Miller, G. R., Moore, G. W.

Small-scale treefall gaps are among the most important forms of forest disturbance in tropical forests. These gaps expose surrounding trees to more light, promoting rapid growth of understory plants. However, the effects of such small-scale disturbances on the distribution of plant water use across tree canopy levels are less known. …

Accounting for canopy structure improves hyperspectral radiative transfer and sun-induced chlorophyll fluorescence representations in a new generation Earth System model
Braghiere,R.K., Wang,Y., Doughty,R., Sousa,D., Magney,T., Widlowski,J.-L., Longo,M., Bloom,A.A., Worden,J., Gentine,P., Frankenberg,C.

Three-dimensional (3D) vegetation canopy structure plays an important role in the way radiation interacts with the land surface. Accurately representing this process in Earth System models (ESMs) is crucial for the modeling of the global carbon, energy, and water cycles and hence future climate projections. Despite the importance …
