Exploring plastic transport dynamics in the Odaw river, Ghana

Pinto, Rose Boahemaa (author), Barendse, Tom (author), van Emmerik, Tim (author), van der Ploeg, Martine (author), Annor, F.O. (author), Duah, Kwame (author), Udo, Job (author), Uijlenhoet, R. (author)

Plastic pollution in rivers threatens ecosystems, increases flood risk due to its accumulations at hydraulic structures and its final emissions into the ocean threaten aquatic life, especially and probably most in coastal urbanized areas. Previous work suggests that plastic pollution in these urban rivers is influenced by hydrometeorological...

Land Cover Control on the Drivers of Evaporation and Sensible Heat Fluxes: An Observation-Based Synthesis for the Netherlands

Jansen, Femke A. (author), Jongen, Harro J. (author), Jacobs, Cor M.J. (author), Bosveld, Fred C. (author), Buzacott, Alexander J.V. (author), Heusinkveld, Bert G. (author), Kruijt, Bart (author), van der Molen, Michiel (author), Uijlenhoet, R. (author)

Land cover controls the land-atmosphere exchange of water and energy through the partitioning of solar energy into latent and sensible heat. Observations over all land cover types at the regional scale are required to study these turbulent flux dynamics over a landscape. Here, we aim to study how the control of daily and midday latent and...

Recent studies have shown the promising potential of using deep learning models for precipitation nowcasting. In this paper, novel deep generative models are proposed for precipitation nowcasting....

Scale-dependent blending of ensemble rainfall nowcasts and numerical weather prediction in the open-source pysteps library

Imhoff, Ruben O. (author), De Cruz, Lesley (author), Dewettinck, Wout (author), Brauer, Claudia C. (author), Uijlenhoet, R. (author), van Heeringen, Klaas Jan (author), Velasco-Forero, Carlos (author), Nerini, Daniele (author), Van Ginderachter, Michiel (author), Weerts, Albrecht H. (author)

Flash flood early warning requires accurate rainfall forecasts with a high spatial and temporal resolution. As the first few hours ahead are already not sufficiently well captured by the rainfall forecasts of numerical weather prediction (NWP) models, radar rainfall nowcasting can provide an alternative. Because this observation-based method...

Extreme Precipitation Nowcasting using Deep Generative Models

Bi, H. (author), Kyryliuk, M.S. (author), Wang, Z. (author), Meo, C. (author), Wang, Y. (author), Imhoff, Ruben (author), Uijlenhoet, R. (author), Dauwels, J.H.G. (author)

Extreme precipitation usually leads to substantial impacts. Floods in the Netherlands, Belgium and Germany in the summer of 2021 have caused loss of lives, destruction of infrastructures, and long-term effect on economics. To avoid such disasters, it is important to develop a reliable and accurate method to predict heavy rain.

Wolff, Wagner (author), Overeem, A. (author), Leijnse, Hidde (author), Uijlenhoet, R. (author)

During the last decade, rainfall monitoring using signal-level data from commercial microwave links (CMLs) in cellular communication networks has been proposed as a complementary way to estimate rainfall for large areas. Path-Averaged rainfall is retrieved between the transmitting and receiving cellular antennas of a CML. One rainfall...

A probabilistic climate change assessment for Europe

Moghim, Sanaz (author), Teuling, Adriaan J. (author), Uijlenhoet, R. (author)

Globally, the impacts of climate change can vary across different regions. This study uses a probability framework to evaluate recent historical (1976–2016) and near-future projected (until 2049) climate change across Europe using Climate Research Unit and ensemble climate model datasets (under RCPs 2.6 and 8.5). A historical assessment shows...

Ongoing urbanization highlights the need for a better understanding and high resolution modelling of the urban climate. In this study, we combine rural observations by WMO surface stations, weather radar data and urban crowd-sourced observations with very fine-scale modelling efforts for Amsterdam, The Netherlands. As a model, we use the...

Large-Sample Evaluation of Radar Rainfall Nowcasting for Flood Early Warning

Imhoff, R. O. (author), Brauer, C. C. (author), van Heeringen, K. J. (author), Uijlenhoet, R. (author), Weerts, A. H. (author)

To assess the potential of radar rainfall nowcasting for early warning, nowcasts for 659 events were used to construct discharge forecasts for 12 Dutch catchments. Four open-source nowcasting algorithms were tested: Rainymotion Sparse (RM-S), Rainymotion DenseRotation (RM-DR), Pysteps deterministic (PS-D), and probabilistic (PS-P) with 20...

The monitoring of wildfire smoke is important to help mitigate impacts on people such as by sending early warnings to affected areas. Received signal levels (RSLs) from radio links have been used as an opportunistic way to accurately measure rainfall and humidity. Radio links provide integrated measurements along their paths and are an...

Commercial microwave links (CMLs) from cellular telecommunication networks can provide a valuable 'opportunistic' source of high-resolution space-time rainfall information, complementing traditional in-situ measurement devices (rain gauges, disdrometers) and remote sensors (weather radars, satellites). Their greatest potential lies in areas...

Imhoff, Ruben (author), Brauer, Claudia (author), Van Heeringen, Klaas Jan (author), Leijnse, Hidde (author), Overeem, Aart (author), Weerts, Albrecht (author), Uijlenhoet, R. (author)

The presence of significant biases in real-time radar quantitative precipitation estimations (QPEs) limits its use in hydrometeorological forecasting systems. Here, we introduce CARROTS (Climatology-based Adjustments for Radar Rainfall in an OperaTional Setting), a set of fixed bias reduction factors, which vary per grid cell and day of the...

Overeem, A. (author), de Vries, Hylke (author), Sakka, Hassan Al (author), Uijlenhoet, R. (author), Leijnse, Hidde (author)

The Royal Netherlands Meteorological Institute (KNMI) operates two operational dual-polarization C-band weather radars providing 2D radar rainfall products. Attenuation can result in severe underestimation of rainfall amounts, particularly in convective situations that are known to have high impact on society. To improve the radar-based...
