Citizen rain gauges improve hourly radar rainfall bias correction using a two-step Kalman filter [PDF]

open access: yesHydrology and Earth System Sciences, 2022
The low density of conventional rain gauge networks is often a limiting factor for radar rainfall bias correction. Citizen rain gauges offer a promising opportunity to collect rainfall data at a higher spatial density.

Large-scale rain gauge network optimization using a kriging emulator

open access: yesJournal of Hydrology
Rain gauge networks deliver crucial observations for many water-related applications but can be expensive to purchase and operate, which makes optimization of the number and locations of gauges an important task. Traditional optimization approaches often focus on kriging-based methods that are computationally expensive, which limits the scale of the ...

An Innovative Acoustic Rain Gauge Based on Convolutional Neural Networks [PDF]

open access: yesInformation, 2020
An accurate estimate of rainfall levels is fundamental in numerous application scenarios: weather forecasting, climate models, design of hydraulic structures, precision agriculture, etc. An accurate estimate becomes essential to be able to warn of the imminent occurrence of a calamitous event and reduce the risk to human beings. Unfortunately, to date,

Benefits from high-density rain gauge observations for hydrological response analysis in a small alpine catchment [PDF]

open access: yesHydrology and Earth System Sciences, 2021
Spatial rainfall patterns exert a key control on the catchment-scale hydrologic response. Despite recent advances in radar-based rainfall sensing, rainfall observation remains a challenge, particularly in mountain environments.

Optimization of Rain Gauge Networks for Arid Regions Based on Remote Sensing Data [PDF]

open access: yesRemote Sensing, 2021
Water depletion is a growing problem in the world’s arid and semi-arid areas, where groundwater is the primary source of fresh water. Accurate climatic data must be obtained to protect municipal water budgets. Unfortunately, the majority of these arid regions have a sparsely distributed number of rain gauges, which reduces the reliability of the spatio-
