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. ...

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, ...

Ma, Qiumei; Xiong, Lihua; Liu, Dedi; Xu, Chong-Yu; Guo, Shenglian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Satellite precipitation estimates (SPE), characterized by high spatial-temporal resolution, have been increasingly applied to hydrological modeling. However, the errors and bias inherent in SPE are broadly recognized. Yet, ...

Yan, Lei; Zhang, Liying; Xiong, Lihua; Yan, Pengtao; Jiang, Cong; Xu, Wentao; Xiong, Bin; Yu, Kunxia; Ma, Qiumei; Xu, Chong-Yu (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)The fundamental assumption of flood frequency analysis is that flood samples are generated by the same flood generation mechanism (FGM). However, flood events are usually triggered by the interaction of meteorological ...

Chen, Shilei; Xiong, Lihua; Ma, Qiumei; Kim, Jong-Suk; Chen, Jie; Xu, Chong-Yu (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)Merging gauge observation with a single original satellite-based precipitation product (SPP) is a common approach to generate spatial precipitation estimates. For the generation of high-quality precipitation maps, however, ...

Ma, Qiumei; Ji, Changming; Xiong, Lihua; Wang, Yi; Xu, Chong-Yu; Zhang, Yanke (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)Given the threats from rainstorm events that have been intensified due to climate change, the investigation of heavy/extreme precipitation is attracting increasing attention. The investigation of extreme precipitation, ...

Yang, Han; Xiong, Lihua; Ma, Qiumei; Xia, Jun; Chen, Jie; Xu, Chong-Yu (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The traditional calibration objective of hydrological models is to optimize streamflow simulations. To identify the value of satellite soil moisture data in calibrating hydrological models, a new objective of optimizing ...
