Bias-corrected precipitation products in a data-scarce Andean basin: performance and parameter transferability
ABSTRACT Sparse monitoring networks and complex topography in mountainous regions reduce the reliability of precipitation records, limiting their use in hydrological and engineering analyses. In the tropical Andes, large-scale circulation patterns and strong orographic gradients amplify these challenges, making gridded...

Multi-Scale Validation of Satellite-Based Precipitation Products and Their Impacts on Hydrological Simulation in a Humid Mountainous Basin
Accurate precipitation information is crucial for hydrological simulation and water resources management, especially in humid mountainous regions where complex terrain and spatially heterogeneous rainfall introduce considerable uncertainties. Satellite-based precipitation products provide important data sources for hyd...

Long-Term Evaluation of Satellite Precipitation Products for Extreme Rainfall and Water-Related Hazard Assessment Along a Mountainous Corridor in Northern Vietnam
Accurate rainfall information is essential for water-related hazard assessment in mountainous regions, where complex terrain and sparse gauge networks limit monitoring reliability. This study evaluated long-term rainfall characteristics and the performance of three satellite precipitation products—CHIRPS, GPM IMERG, an...

Undercatch corrected gridded precipitation data to improve hydrological modeling in high-alpine orography
Stationary precipitation measurements are frequently affected by undercatch errors, which are particularly pronounced in cold and alpine regions with strong winds. Since gridded precipitation products used in land surface modeling are often derived from spatial interpolation of meteorological station data, these meas...

Toward reliable water resource assessment: Correcting bias in satellite-based rainfall and model-derived discharge in Kenya’s Central Highlands
Reliable precipitation and streamflow data are essential for hydrological modelling and water resources management, yet observational networks in many African regions remain sparse. This study evaluated five satellite precipitation products (SPPs) CHIRPS, PERSIANN-CCS, PERSIANN-PDIR, TAMSAT, and MSWEP and modelled stre...

A High-Accuracy Gridded Precipitation Dataset for Southeast Asia Developed Using Extended Triple Collocation Analysis
Accurate daily gridded precipitation estimates are needed to characterize spatial rainfall variability and support retrospective hydrological analysis in Southeast Asia, where complex rainfall regimes and sparse rain gauge coverage remain major challenges. This study develops an Extended Triple Collocation Analysis (ET...
