Detection of large acoustic energy flux in the solar atmosphere

, 2010
We study the energy flux carried by acoustic waves excited by convective motions at sub-photospheric levels. The analysis of high-resolution spectropolarimetric data taken with IMaX/Sunrise provides a total energy flux of ~ 6400--7700 Wm$^{-2}$ at a ...

A case study of temperature tendency mechanisms operating over northern Africa during and following midlatitude winter troughs

Quarterly Journal of the Royal Meteorological Society, EarlyView.
An Iberia‐Central Mediterranean trough sequence (7–10 February 2018) delivers anomalous low‐level temperature tendencies attributable to dynamics across most of northern Africa, with warming over northeastern Africa, especially 10–12 February into the eastern Sahel. An ECMWF product attributes the tendencies (see Figure).

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 ...

Maximum Entropy Limit of Small-scale Magnetic Field Fluctuations in the Quiet Sun

, 2017
The observed magnetic field on the solar surface is characterized by a very complex spatial and temporal behavior. Although feature-tracking algorithms have allowed us to deepen our understanding of this behavior, subjectivity plays an important role in ...

Impact of parameterization in multiple acoustic index comparisons: practical cases in terrestrial and underwater soundscapes

Remote Sensing in Ecology and Conservation, EarlyView.
Parameter choices in acoustic analyses (sampling frequency, FFT size and window overlap) strongly influence multivariate soundscape separation. Using terrestrial and coral reef recordings, we show that these settings can exaggerate or mask ecological differences, emphasizing the need for parameter sensitivity testing and transparent reporting in ...

Dispersive Calculation of the Massless Multi-loop Sunrise Diagram [PDF]

, 2018
The massless sunrise diagram with an arbitrary number of loops is calculated in a simple but formal manner. The result is then verified by rigorous mathematical treatment. Pitfalls in the calculation with distributions are highlighted and explained.
