A Cluster‐Based Data Assimilation Approach to Generate New Daily Gridded Time Series Precipitation Data in the Himalayan River Basins

Water Resources Research, Volume 61, Issue 1, January 2025.
Abstract Recent studies show variations in precipitation‐gridded data set accuracy with changing geographical parameters. Ensemble precipitation products, combining diverse data sets, offer global‐scale effectiveness, but applying them to regional studies, particularly in small to medium‐sized sub‐basins, presents challenges in addressing precipitation

Analysis of hydrological changes and flood increase in Niamey based on the PERSIANN-CDR satellite rainfall estimate and hydrological simulations over the 1983–2013 period [PDF]

Proceedings of the International Association of Hydrological Sciences, 2015
Abstract. A dramatic increase in the frequency and intensity of floods due to the Niger River in the city of Niamey (Niger) has been observed in the last decade. Previous studies highlighted the role of the land use changes on the flood increase since 1970s.

Synoptic Patterns and Effects of Topography on Occurrences of Heavy Rainfall in Northwest Vietnam

Advances in Meteorology, Volume 2025, Issue 1, 2025.
Accurate forecasting of local heavy rainfall distribution over Northwest Vietnam is challenging due to the regions’s complex rainfall processes and topography. In this study, effect of the Hoang Lien Son (HLS) Mountain range on synoptic‐dynamic processes associated with the heavy rainfall were analyzed to quantify the relationship with the local ...

Comparing Satellite, Reanalysis, Fused and Gridded (In Situ) Precipitation Products Over Türkiye

International Journal of Climatology, Volume 44, Issue 16, Page 5873-5889, 30 December 2024.
Flowchart of the study (RE‐organised ranks show the real position of precipitation products). Stations along Türkiye belong to each metric is averaged over continuous, discrete and timing, and re‐ranked from best to worst. Final ranks belong to metrics also is averaged and best precipitation product is determined.

Characterizing Asymptotic Dependence between a Satellite Precipitation Product and Station Data in the Northern US Rocky Mountains via the Tail Dependence Regression Framework With a Gibbs Posterior Inference Approach

Environmetrics, Volume 35, Issue 8, December 2024.
ABSTRACT The use of satellite precipitation products (SPP) allows for precipitation information to be collected nearly globally, but questions remain regarding their ability to reproduce extreme precipitation over mountainous terrain. In this work, we assess the ability of the precipitation estimation from remotely sensed information using artificial ...

The Conditional Bias of Extreme Precipitation in Multi‐Source Merged Data Sets

Geophysical Research Letters, Volume 51, Issue 22, 28 November 2024.
Abstract Multi‐source data merging via weighted average (WA) is widely applied to enhance large‐scale precipitation estimates. However, these data sets usually contain substantial conditional biases with respect to extreme precipitation (EP) events—undermining their utility for extreme event analysis.

Disaggregating radar-derived rainfall measurements in East Azarbaijan, Iran, using a spatial random-cascade model [PDF]

, 2016
The availability of spatial, high-resolution rainfall data is one of the most essential needs in the study of water resources. These data are extremely valuable in providing flood awareness for dense urban and industrial areas.
