Vegetation Source Water Identification Using Isotopic And Hydrometric Observations From A Subhumid Mountain Catchment
Dwivedi, R., Eastoe, C., Knowles, J. F., Wright, W. E., Hamann, L., Minor, R., Mitra, B., Meixner, T., McIntosh, J., Ty Ferre, P. A., Castro, C., Niu, G., Barron‐Gafford, G. A., Abramson, N., Papuga, S. A., Stanley, M., Hu, J., Chorover, J.

This study coupled long‐term hydrometric and stable water isotope data to identify links between subsurface water storage and vegetation in a subhumid mountain catchment in Arizona, USA. Specific observations included catchment‐scale hydrologic fluxes and soil water storage and stable water isotopes from stream water, soil water, …

Methane Emission Reductions From The Alternate Wetting And Drying Of Rice Fields Detected Using The Eddy Covariance Method
Runkle, B. R., Suvočarev, K., Reba, M. L., Reavis, C. W., Smith, S. F., Chiu, Y., Fong, B.

Rice cultivation contributes 11% of the global 308 Tg CH4 anthropogenic emissions. The alternate wetting and drying (AWD) irrigation practice can conserve water while reducing CH4 emissions through the deliberate, periodic introduction of aerobic soil conditions. This paper is the first to measure the impact of AWD on rice field …

Surface Renewal Measurements Of H, λE And Co2 Fluxes Over Two Different Agricultural Systems
Suvočarev, K., Castellví, F., Reba, M., Runkle, B.

The importance of understanding turbulent scalar exchange over agricultural landscapes motivated this study of the surface renewal (SR) method for deployment in place of or alongside eddy covariance (EC) instrumentation. High-frequency (20 Hz) scalar data were used with turbulence and similarity parameters for SR measurements of …

An Analytical Model For Estimation of Land Surface Net Water Flux From Near-Surface Soil Moisture Observations
Sadeghi, M., Tuller, M., Warrick, A. W., Babaeian, E., Parajuli, K., Gohardoust, M. R., Jones, S. B.

The accurate determination of land surface water fluxes at various spatiotemporal scales remains a challenge in hydrological sciences. It is intuitive that land surface net water flux (i.e., infiltration minus evapotranspiration) directly affects near-surface soil moisture. However, there exists no hydrological model suitable to …

Reviews And Syntheses: Turning The Challenges Of Partitioning Ecosystem Evaporation And Transpiration Into Opportunities
Stoy, P. C., El-Madany, T. S., Fisher, J. B., Gentine, P., Gerken, T., Good, S. P., Klosterhalfen, A., Liu, S., Miralles, D. G., Perez-Priego, O., Rigden, A. J., Skaggs, T. H., Wohlfahrt, G., Anderson, R. G., Coenders-Gerrits, A. M., Jung, M., Maes, W. H., Mammarella, I., Mauder, M., Migliavacca, M., Nelson, J. A., Poyatos, R., Reichstein, M., Scott, R. L., Wolf, S.

Evaporation (E) and transpiration (T) respond differently to ongoing changes in climate, atmospheric composition, and land use. It is difficult to partition ecosystem-scale evapotranspiration (ET) measurements into E and T, which makes it difficult to validate satellite data and land surface models. Here, we review current progress …

Experimental Influence Of Storm-Surge Salinity On Soil Greenhouse Gas Emissions From A Tidal Salt Marsh
Capooci, M., Barba, J., Seyfferth, A. L., Vargas, R.

Storm surges can substantially alter the water level and salinity in tidal salt marshes. Little is known about how changes experienced during storm surges affect greenhouse gas emissions (GHG; CO2, CH4, N2O) from tidal salt marsh soils. Understanding how storm surges influence ecosystem processes is critical for evaluating the ecosystem’s …

The Spatial Variability Of Actual Evapotranspiration Across The Amazon River Basin Based On Remote Sensing Products Validated With Flux Towers
Paca, V. H., Espinoza-Dávalos, G. E., Hessels, T. M., Moreira, D. M., Comair, G. F., Bastiaanssen, W. G.

Actual evapotranspiration (ET) is a major component of the water balance. While several international flux measurement programs have been executed in the tropical rain forest of the Amazon, those measurements represent the evaporative process at a few selected sites only. The aim of this study is to obtain the spatial distribution …
