Lightning electromagnetic emission location using arrival time differencing (LEELA): An introduction to the Met Office's next generation Very Low Frequency lightning location system

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This paper describes the Met Office's new lightning location system LEELA. A brief overview of the upgraded hardware and geolocation algorithms is given. LEELA has improved lightning detection capabilities, especially at night. When comparing LEELA to the previous ATDnet system against ground truths LEELA has 100% storm detection efficiency within 5 km

Optical Turbulence Characterization for Ground-Based Astronomy

, 2010
The optical turbulence, which creates perturbations of the wavefronts coming from the stars, is caused by small-scale fluctuations in the index of refraction of the atmosphere and is a problem for astronomers because it limits the maximum resolution of the ground-based telescopes.

Enhancing severe convection forecasts with microwave radiance assimilation in limited‐area models

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Microwave satellite radiances remain largely underexploited in convection‐permitting limited‐area models. We assess the assimilation of humidity‐sensitive radiances from the MHS instrument in the operational ICON‐2I model, improving the precipitation forecast of a severe convective event over the Marche region, Italy, substantially by correcting ...

Sliding Mode Control in Aerospace Applications: A Survey

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

Straintronics and Twistronics in 2D Materials: Structural Control and Predictive Design

Small, EarlyView.
Strain and twist engineering in 2D materials is established as a programmable design parameter responsible for reconstructing lattices, tuning interlayer coupling, and developing new quantum functionalities. Through the integration of advanced fabrication techniques, multiscale characterization, computational modeling, and machine learning, this review

Investigation of Tin Oxide Atomic Layer Deposition on the Performance of Evaporated Perovskite Solar Cells

Small, EarlyView.
Impact of co‐reactants and their doses utilized during the atomic layer deposition of SnOx on perovskite/C60 structures on the performance of p‐i‐n perovskite solar cells. ABSTRACT Although tin oxide (SnOx) layers grown using atomic layer deposition (ALD) are routinely employed in p‐i‐n perovskite solar cells (PSCs), the correlation between ALD process
