Century-long increasing trend and variability of dissolved organic carbon export from the Mississippi River basin driven by natural and anthropogenic forcing 

Ren, Wei; Tian, Hanqin; Cai, Wei-Jun; Lohrenz, Steven E.; Hopkinson, Charles S; Huang, Wei-Jen; Yang, Jia; Tao, Bo; Pan, Shufen; He, Ruoying; 0000-0002-1806-4091; 0000-0001-7920-1427 (2020-04-02)
There has been considerable debate as to how natural forcing and anthropogenic activities alter the timing and magnitude of the delivery of dissolved organic carbon (DOC) to the coastal ocean, which has ramifications for ...

Development of a REgion‐Specific Ecosystem Feedback Fire (RESFire) Model in the Community Earth System Model 

Zou, Yufei; Wang, Yuhang; Ke, Ziming; Tian, Hanqin; Yang, Jia; Liu, Yongqiang; 0000-0002-1806-4091 (2020-04-01)
Fires play a critical role in modulating regional and global climate through disturbances on meteorological, biogeochemical, and hydrological processes, while fires are strongly affected by climate, terrestrial ecosystems, ...

Global Nitrous Oxide Emissions From Pasturelands and Rangelands: Magnitude, Spatiotemporal Patterns, and Attribution 

Dangal, Shree R. S.; Tian, Hanqin; Xu, Rongting; Chang, Jinfeng; Canadell, Josep G.; Ciais, Philippe; Pan, Shufen; Yang, Jia; Zhang, Bowen; 0000-0002-1806-4091; 0000-0001-7920-1427 (2020-04-01)
The application of manure and mineral nitrogen (N) fertilizer, and livestock excreta deposition are the main drivers of nitrous oxide (N2O) emissions in agricultural systems. However, the magnitude and spatiotemporal ...

Improving Representation of Crop Growth and Yield in the Dynamic Land Ecosystem Model and Its Application to China 

Zhang, Jingting; Tian, Hanqin; Yang, Jia; Pan, Shufen; (2022-07-29)
To accurately assess the roles of agriculture in securing food security and maintaining environmental sustainability, it is essential to improve the representation of crop growth, development, and yield formation in global ...

Increasing Mississippi river discharge throughout the 21st century influenced by changes in climate, land use, and atmospheric CO2 

Tao, Bo; Tian, Hanqin; Ren, Wei; Yang, Jia; Yang, Qichun; He, Ruoying; Cai, Weijun; Lohrenz, Steven (2022-09-15)
Previous studies have demonstrated that changes in temperature and precipitation (hereafter climate change) would influence river discharge, but the relative importance of climate change, land use, and elevated atmospheric ...

Long-term trends in evapotranspiration and runoff over the drainage basins of the Gulf of Mexico during 19012008 

Liu, Mingliang; Tian, Hanqin; Yang, Qichun; Yang, Jia; Song, Xia; Lohren, Steven E.; Cai, Wei-Jun; 0000-0002-1806-4091 (2020-04-01)
The Gulf of Mexico (GOM) is facing large pressures from environmental changes since the beginning of the last century. However, the magnitude and long-term trend of total water discharge to the GOM and the underlying ...

Methane emissions from global rice fields: Magnitude, spatiotemporal patterns, and environmental controls 

Zhang, Bowen; Tian, Hanqin; Ren, Wei; Tao, Bo; Lu, Chaoqun; Yang, Jia; Banger, Kamaljit; Pan, Shufen; 0000-0002-1806-4091; 0000-0001-7920-1427 (2020-04-02)
Given the importance of the potential positive feedback between methane (CH4) emissions and climate change, it is critical to accurately estimate the magnitude and spatiotemporal patterns of CH4 emissions from global rice ...
