Ma, Qiumei; Xiong, Lihua; Xia, Jun; Xiong, Bin; Yang, Han; Xu, Chong-Yu (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Satellite precipitation estimates (SPE) provide useful input for hydrological modeling. However, hydrological modeling is frequently hindered by large bias and errors in SPE, inducing the necessity for bias corrections. ...

Wang, Chengyun; Chen, Jie; Gu, Lei; Wu, Guiyang; Tong, Shanlin; Xiong, Lihua; Xu, Chong-Yu (Journal article / Tidsskriftartikkel / SubmittedVersion, 2023)Soil moisture drought, as one of the most important drought categories, is determined by both water supply (e.g., precipitation) and demand (e.g., potential evapotranspiration). To shed light on the underlying mechanisms ...

Ma, Qiumei; Xiong, Lihua; Xu, Chong-Yu; Guo, Shenglian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Satellite precipitation estimates (SPE) product with high spatiotemporal resolution is a potential alternative to traditional ground-based gauge precipitation. However, SPE is frequently biased due to its indirect measurement, ...

Xiong, Bin; Xiong, Lihua; Xia, Jun; Xu, Chong-Yu; Jiang, Cong; Du, Tao (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Many studies have shown that downstream flood regimes have been significantly altered by upstream reservoir operation. Reservoir effects on the downstream flow regime are normally performed by comparing the pre-dam and ...

Yan, Lei; Lu, Dongyang; Xiong, Lihua; Wang, Hongfeng; Luan, Qinghua; Jiang, Cong; Xiong, Bin; Xu, Wentao; Yan, Pengtao; Lei, Qingwen; Xu, Chong-Yu (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)Urban infrastructure traditionally relies on stationary rainfall intensity-duration-frequency (IDF) curves. However, this assumption is challenged by climate change and urbanization. Many studies tried to update IDF using ...

Detection and Attribution of Norwegian Annual Precipitation Variability Related to Teleconnections Zhou, Yanlai; Ruan, Gusong; Xu, Chong-Yu; Xiong, Lihua; Jain, Sharad K.; Li, Lu (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Detection and attribution of precipitation variability are fundamentally challenging, especially in the presence of complex nonlinear relationships between precipitation variability and large-scale teleconnections. The aim ...

-
Xiong, Lihua; Yang, Han; Zeng, Ling; Xu, Chong-Yu (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Accurate soil moisture estimation plays a crucial role in agricultural management and hydrological studies. Considering the scarcity of direct in-situ measurements, it is important to evaluate the consistency of soil ...
