Oxygen isotope composition of evapotranspiration and its relation to C4 photosynthetic discrimination
Timothy J. Griffis,Xuhui Lee,John M. Baker,K. Billmark,Natalie M. Schultz,M. Erickson,Xin Zhang,Joel J. Fassbinder,Wei Xiao,Ning Hu +9 more
TL;DR: In this article, simultaneous observations of 18O-H2O (liquid and vapor phases) and CO2 were used to investigate the relation between canopy leaf water 18O enrichment, 18O CO2 photosynthetic discrimination (18Δ), isotope disequilibrium (Deq), and the biophysical factors that control their temporal variability in a C4 (Zea mays L.) ecosystem.

Large methane emissions from natural gas vehicles in Chinese cities
TL;DR: In this paper, the authors used street-level measurement of atmospheric CH4 and CO2 concentrations to quantify CH4 emissions from natural gas vehicles (NGVs) in China and found that the overall emission factor is much larger than the tailpipe emission factor indicating that onroad vehicle gas leakage is a widespread problem.

Anthropogenic Methane Emission and Its Partitioning for the Yangtze River Delta Region of China
Cheng Hu,Cheng Hu,Cheng Hu,Timothy J. Griffis,Shoudong Liu,Wei Xiao,Ning Hu,Wenjing Huang,Dong Yang,Xuhui Lee,Xuhui Lee +10 more
TL;DR: In this article, the authors estimate anthropogenic CH4 emissions in the Yangtze River Delta (YRD) region of China, where a large number of cities are located, by combining the atmospheric CH4 and CO2 mixing ratio measurements from June 2010 to April 2011.

Quantifying nitrous oxide fluxes on multiple spatial scales in the Upper Midwest, USA
Xin Zhang,Xin Zhang,Xuhui Lee,Timothy J. Griffis,Arlyn E. Andrews,John M. Baker,M. Erickson,Ning Hu,Wei Xiao +8 more
TL;DR: The direct N2O emission from cropland accounted for less than 20 % of the regional flux, suggesting a significant influence by other sources and indirect emissions, in the regional N 2O budget.
