Evaluating meteorological reanalysis for identifying fair‐weather conditions in historical atmospheric electricity data

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Atmospheric electricity data require local weather information for identifying representative ‘fair weather’ values, which are needed for climate‐related studies. ERA5 meteorological reanalysis data are evaluated for this, by comparison with data from Lerwick observatory, Shetland, where a long series of twentieth‐century potential gradient ...

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

open access: yesQuarterly 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 ...

Meteorological conditions leading to a catastrophic, rain‐induced landslide in Cameroon in October 2019

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
October 2019 was characterized by three main multiday wet spells in Bafoussam and Dschang. Our results indicated that wet spells were influenced by a vortex pair near the Gulf of Guinea, a strong Sahara Heat Low located anomalously far east and north, a northward shift of the intertropical discontinuity, an enhancement of the inland penetration of the ...

Hyperspectral imaging has a limited ability to remotely sense the onset of beech bark disease

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Although hyperspectral imaging is a powerful remote sensing tool, it proved ineffective in predicting the progression of beech bark disease, except in its later stages, both at the canopy and leaf levels. While some alterations in chlorophyll, water content, and canopy structure may have influenced foliar reflectance at the canopy scale, as suggested ...

Quantifying aboveground herbaceous biomass in grassy ecosystems: a comparison of field and high‐resolution UAV‐LiDAR approaches

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
The abundance of herbaceous vegetation in grassy ecosystems—which cover >25% of the world's land surface—is highly variable and impacts key ecological processes including carbon sequestration and support for grazing wildlife and livestock. Here, we present a method for using high‐resolution, UAV‐borne Light Detection and Ranging (LiDAR) to estimate ...
