UAV-Based Remote Sensing of Soil Moisture Across Diverse Land Covers: Validation and Bayesian Uncertainty Characterization
Runze Zhang, Ishfaq Aziz, Derek Houtz +4
High-resolution soil moisture (SM) observations are critical for agricultural monitoring, forestry management, and hazard prediction, yet current satellite passive microwave missio…
Exploring the conditions conducive to convection within the Greenland Ice Sheet
Robert Law, Andreas Born, Philipp Voigt +2
Large plume-like features within the Greenland Ice Sheet disrupt radiostratigraphy and complicate the use of isochrones in reconstructions of past ice dynamics. Here we use numeric…
A solar rotation signature in cosmic dust: frequency analysis of dust particle impacts on the Wind spacecraft
Lennart R. Baalmann, Silvan Hunziker, Arthur Péronne +7
Dust particle impacts on the Wind spacecraft were detected with its plasma wave instrument Wind/WAVES. Frequency analysis on this dust impact time series revealed spectral peaks in…
Sub-Meter Remote Sensing of Soil Moisture Using Portable L-band Microwave Radiometer
Runze Zhang, Abhi Nayak, Derek Houtz +3
Spaceborne microwave passive soil moisture products are known for their accuracy but are often limited by coarse spatial resolutions. This limits their ability to capture finer soi…
OAM-TCD: A globally diverse dataset of high-resolution tree cover maps
Josh Veitch-Michaelis, Andrew Cottam, Daniella Schweizer +5
Accurately quantifying tree cover is an important metric for ecosystem monitoring and for assessing progress in restored sites. Recent works have shown that deep learning-based seg…
Drag reduction utilizing a wall-attached ferrofluid film in turbulent channel flow
Marius M. Neamtu-Halic, Markus Holzner, Laura M. Stancanelli
This study explores the application of a wall-attached ferrofluid film to decrease skin friction drag in turbulent channel flow. We conduct experiments using water as a working flu…
Novel community data in ecology -- properties and prospects
Florian Hartig, Nerea Abrego, Alex Bush +14
New technologies for acquiring biological information such as eDNA, acoustic or optical sensors, make it possible to generate spatial community observations at unprecedented scales…
Distributed Parallelization of xPU Stencil Computations in Julia
Samuel Omlin, Ludovic Räss, Ivan Utkin
We present a straightforward approach for distributed parallelization of stencil-based xPU applications on a regular staggered grid, which is instantiated in the package ImplicitGl…
High-performance xPU Stencil Computations in Julia
Samuel Omlin, Ludovic Räss
We present an efficient approach for writing architecture-agnostic parallel high-performance stencil computations in Julia, which is instantiated in the package ParallelStencil.jl.…
Modelling Cosmic Radiation Events in the Tree-ring Radiocarbon Record
Qingyuan Zhang, Utkarsh Sharma, Jordan A. Dennis +6
Annually-resolved measurements of the radiocarbon content in tree-rings have revealed rare sharp rises in carbon-14 production. These 'Miyake events' are likely produced by rare in…
Universal alignment in turbulent pair dispersion
Ron Shnapp, Stefano Brizzolara, Marius M. Neamtu-Halic +2
Countless processes in nature and industry, from rain droplet nucleation to plankton interaction in the ocean, are intimately related to turbulent fluctuations of local concentrati…
Splitting of localized disturbances in viscoelastic channel flow
Ron Shnapp, Victor Steinberg
We examine the response of an inertia-less viscoelastic channel flow to localized perturbations. A simplified model shows that the non-linear interaction between the velocity and e…
Predicting Chemical Hazard across Taxa through Machine Learning
Jimeng Wu, Simone D'Ambrosi, Lorenz Ammann +3
We applied machine learning methods to predict chemical hazards focusing on fish acute toxicity across taxa. We analyzed the relevance of taxonomy and experimental setup, showing t…
Transition from shear-dominated to Rayleigh-Taylor turbulence
Stefano Brizzolara, Jean-Paul Mollicone, Maarten van Reeuwijk +2
Turbulent mixing layers in nature are often characterized by the presence of a mean shear and an unstable buoyancy gradient between two streams of different velocity. Depending on…
Fiber Tracking Velocimetry for two-point statistics of turbulence
Stefano Brizzolara, Marco Edoardo Rosti, Stefano Olivieri +3
We propose and validate a novel experimental technique to measure two-point statistics of turbulent flows. It consists in spreading rigid fibers in the flow and tracking their posi…
Role of vortical structures for enstrophy and scalar transport in flows with and without stable stratification
M. M. Neamtu-Halic, J. -P. Mollicone, M. van Reeuwijk +1
In this paper, we investigate the enstrophy dynamics in relation to objective Eulerian coherent structures (OECSs) and their impact on the enstrophy and scalar transport near the t…
National mapping and estimation of forest area by dominant tree species using Sentinel-2 data
Johannes Breidenbach, Lars T. Waser, Misganu Debella-Gilo +5
Nation-wide Sentinel-2 mosaics were used with National Forest Inventory (NFI) data for modelling and subsequent mapping of spruce, pine and deciduous forest in Norway in 16 m $\tim…
Efficient mate finding in planktonic copepods swimming in turbulence
François-Gaël Michalec, Itzhak Fouxon, Sami Souissi +1
Zooplankton live in dynamic environments where turbulence may challenge their limited swimming abilities. How this interferes with fundamental behavioral processes remains elusive.…
Objective barriers to the transport of dynamically active vector fields
George Haller, Stergios Katsanoulis, Markus Holzner +2
We derive a theory for material surfaces that maximally inhibit the diffusive transport of a dynamically active vector field, such as the linear momentum, the angular momentum or t…
