Journal ArticleDOI
Biophysical controls on interannual variability in ecosystem-scale CO2 and CH4 exchange in a California rice paddy
Sara H. Knox,Jaclyn Hatala Matthes,Cove Sturtevant,Patricia Y. Oikawa,Joseph Verfaillie,Dennis D. Baldocchi +5 more
TL;DR: In this paper, the authors present 6.5 years of eddy covariance measurements of fluxes of methane (FCH4) and carbon dioxide (FCO2) from a flooded rice paddy in Northern California, USA.
Journal ArticleDOI
Unusually high soil nitrogen oxide emissions influence air quality in a high-temperature agricultural region
Patricia Y. Oikawa,Cui Ge,Jun Wang,J. R. Eberwein,Liyin L. Liang,Lindy A. Allsman,David A. Grantz,G. D. Jenerette +7 more
TL;DR: It is found that a regional air chemistry model often underestimates soil NOx emissions and NOx at the surface and in the troposphere, and adjusting the model to match NOx observations leads to elevated tropospheric O3.
Journal ArticleDOI
Identifying scale-emergent, nonlinear, asynchronous processes of wetland methane exchange
Cove Sturtevant,Benjamin L. Ruddell,Sara H. Knox,Joseph Verfaillie,Jaclyn Hatala Matthes,Patricia Y. Oikawa,Dennis D. Baldocchi +6 more
TL;DR: In this paper, a combination of wavelet analysis and information theory was used to analyze interactions between whole-ecosystem CH4 flux and biophysical drivers in two restored wetlands of Northern California from hourly to seasonal time scales.
Journal ArticleDOI
The effect of land cover type and structure on evapotranspiration from agricultural and wetland sites in the Sacramento-San Joaquin River Delta, California.
Elke Eichelmann,Kyle S. Hemes,Sara H. Knox,Sara H. Knox,Patricia Y. Oikawa,Samuel D. Chamberlain,Cove Sturtevant,Joseph Verfaillie,Dennis D. Baldocchi +8 more
TL;DR: In this paper, the authors measured evapotranspiration using the eddy covariance method over six different sites in the Sacramento-San Joaquin Delta from 2013 to 2016.
Journal ArticleDOI
Unifying soil respiration pulses, inhibition, and temperature hysteresis through dynamics of labile soil carbon and O2
Patricia Y. Oikawa,David A. Grantz,Amitava Chatterjee,J. E. Eberwein,Lindy A. Allsman,G. D. Jenerette +5 more
TL;DR: In this article, the authors presented a unifying approach for interpreting the dynamics of soil respiration in a hot arid agricultural environment, and performed a whole ecosystem wetting experiment with continuous measurement of Rs to study pulse responses to wetting in a heterotrophic system.
