Where numerical weather prediction meets large‐eddy simulations in a convective boundary layer during the FESSTVaL field experiment

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We exploit the Field Experiment on Sub‐mesoscale Spatio‐Temporal Variability in Lindenberg (FESSTVaL) to compare the performance of an NWP model at sub‐km resolutions with a traditional LES model. Focusing on clear‐sky ABL turbulence (June 14), shallow convective clouds and surface radiation (June 27), and deep convective cold pools (June 29), we find ...

Optimized Hybrid Resource Allocation in Wireless Cellular Networks with and without Channel Reassignment

Journal of Computer Systems, Networks, and Communications, 2010
In cellular networks, it is important to determine an optimal channel assignment scheme so that the available channels, which are considered as “limited” resources in cellular networks, are used as efficiently as possible.

Temporal Variability of Atmospheric Total Gaseous Mercury in Windsor, ON, Canada

Atmosphere, 2014
Atmospheric Total Gaseous Mercury (TGM) concentrations were monitored in Windsor, Ontario, Canada, during 2007 to 2011, to investigate the temporal variability of TGM. Over five years, the average concentration was 2.0 ± 1.3 ng/m3.

Characterizing trade‐wind shallow convection regimes in the open sea with a synergy of ship‐based vertical profiling observations

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We use active remote sensing from a ship during the EUREC4$$ {\mathrm{EUREC}}^4 $$A campaign to characterize the environment before, during, and after precipitation in shallow convection. (1) Shallow clouds barely precipitate (only virga). Congestus clouds generate precipitation, occurring less often in the afternoon but with higher cloud fractions. (2)

Unravelling indoor temperature response to summer heat through long‐term crowdsourced observations in Dutch residences

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study analysed and modelled summertime indoor temperature dynamics in the Netherlands using a unique long‐term crowdsourced dataset from seven residences (spanning 2–27 years). Indoor temperatures were found to rise and cool more slowly than outdoors (mean 260 minute lag), with heatwave signals persisting about five days.

Classification of Fog Life‐Cycle Phases Using Ground‐Based and Satellite‐Based Observations

Quarterly Journal of the Royal Meteorological Society, EarlyView.
In this study, the life‐cycle phases of radiation fog events—formation, maturity, and dissipation—are automatically classified at a ground station in Southwest Germany based on visibility trends and thresholds. We demonstrate that visibility detects radiation fog phases effectively, while its combination with ceilometer data can detect the life‐cycle ...

Physically consistent mesoscale model evaluation in complex terrain

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study introduces a novel approach for evaluating mesoscale atmospheric models in complex terrain by selecting physically consistent grid points and applying height‐based corrections. The method corrects for sensor height and terrain elevation differences between model and observations using a time‐varying lapse rate.

DuckNet: an open‐source deep learning tool for waterfowl species identification in UAV imagery

Remote Sensing in Ecology and Conservation, EarlyView.
Using drones with thermal‐RGB sensors and a deep learning model (RetinaNet with ResNet‐50), we surveyed non‐breeding waterfowl across restored wetlands in the Mississippi Alluvial Valley. Our model, DuckNet, achieved high accuracy and offers an open‐source, customizable tool for automated waterfowl detection to support conservation monitoring ...
