China's terrestrial carbon balance: Contributions from multiple global change factors

Tian, Hanqin; Melillo, Jerry; Lu, Chaoqun; Kicklighter, David; Liu, Mingliang; Ren, Wei; Xu, Xiaofeng; Chen, Guangsheng; Zhang, Chi; Pan, Shufen; Liu, Jiyuan; Running, Steven; 0000-0002-1806-4091; 0000-0001-7920-1427 (2022-03-04)

The magnitude, spatial, and temporal patterns of the terrestrial carbon sink and theunderlying mechanisms remain uncertain and need to be investigated. China is importantin determining the global carbon balance in terms ...

Effect of nitrogen deposition on China’s terrestrial carbon uptake in the context of multifactor environmental changes

Lu, Chaoqun; Tian, Hanqin; Liu, Mingliang; Ren, Wei; Xu, Xiaofeng; Chen, Guangshen; Zhang, Chi (2023-09-20)

The amount of atmospheric nitrogen (N) deposited on the land surface has increased globally and by nearly five times in China from 1901 to 2005. Little is known about how elevated reactive N input has affected the carbon ...

Heavy Precipitation Impacts on Nitrogen Loading to the Gulf of Mexico in the 21st Century: Model Projections Under Future Climate Scenarios

Zhang, Jien; Lu, Chaoqun; Crumpton, William; Jones, Christopher; Tian, Hanqin; Villarini, Gabriele; Schilling, Keith; Green, David; 0000-0002-1806-4091; 0000-0001-9566-2370; 0000-0002-0439-003X (2022-12-02)

While spatial heterogeneity of riverine nitrogen (N) loading is predominantly driven by the magnitude of basin-wide anthropogenic N input, the temporal dynamics of N loading are closely related to the amount and timing of ...

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 ...

Net exchanges of CO2, CH4, and N2O between China's terrestrial ecosystems and the atmosphere and their contributions to global climate warming

Tian, Hanqin; Xu, Xiaofeng; Lu, Chaoqun; Liu, Mingliang; Ren, Wei; Chen, Guangsheng; Melillo, Jerry; Liu, Jiyuan; 0000-0002-6553-6514; 0000-0002-1963-5933; 0000-0002-1526-0513; 0000-0002-4840-4835; 0000-0002-1806-4091 (2022-10-25)

China's terrestrial ecosystems have been recognized as an atmospheric CO2 sink; however, it is uncertain whether this sink can alleviate global warming given the fluxes of CH4 and N2O. In this study, we used a process-based ...

Responses of global terrestrial evapotranspiration to climate change and increasing atmospheric CO2 in the 21st century

Pan, Shufen; Tian, Hanqin; Dangal, Shree; Yang, Qichun; Yang, Jia; Lu, Chaoqun; Tao, Bo; Ren, Wei; Ouyang, Zhiyun; 0000-0002-1806-4091; 0000-0002-1526-0513; 0000-0001-9529-8206; 0000-0003-2019-9603; 0000-0002-1526-0513; 0000-0002-4840-4835; 0000-0001-7920-1427; 0000-0002-8689-2550 (2023-06-17)

Quantifying the spatial and temporal patterns of the water lost to the atmosphere through land surface evapotranspiration (ET) is essential for understanding the global hydrological cycle, but remains much uncertain. In ...

Severe Long-Lasting Drought Accelerated Carbon Depletion in the Mongolian Plateau

Lu, Chaoqun; Tian, Hanqin; Yu, Zhen; Pan, Shufen; Dangal, Shree; Zhang, Bowen; Yang, Jin; Pederson, Neil; Hessl, Amy; 0000-0002-1806-4091; 0000-0001-7920-1427; 0000-0001-9529-8206; 0000-0002-8370-0509; 0000-0003-2019-9603 (2020-02-25)

Paleoclimate records identified a severe drought lasting approximately a decade on the Mongolian Plateau during the 2000s, the severity of which was only exceeded by a single drought during the last two millennia. Under ...

Spatial and temporal patterns of nitrogen deposition in China: Synthesis of observational data

Lu, Chaoqun; Tian, Hanqin; 0000-0002-1806-4091 (2022-11-07)

[1] Anthropogenic nitrous pollutant emissions in China significantly increased during the last decades, which contributed to the accelerated nitrogen ( N) deposition. In order to characterize spatial pattern of nitrogen ...
