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

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 ...

Atomic‐Scale Control of Substrate‐Spin Coupling Via Vertical Manipulation of a 2D Metal‐Organic Framework

Small, EarlyView.
A slightly buckled 2D kagome metal‐organic framework (MOF) adsorbed on Ag(111) hosts localized spins which are Kondo‐screened by the underlying metal substrate. Using the tip of a scanning tunneling microscope, the MOF can be vertically manipulated to controllably change its adsorption height and with it, the Kondo coupling strength.

Bimetallic Zn/Cu Metal–Organic Framework (MOF)/ Two‐Dimensional i‐MBene Hybrid Electrodes for Enhanced Supercapacitor Performance

Small, EarlyView.
A Zn/Cu MOF–i‐MBene hybrid electrode (ZC‐MYB) for supercapacitors is developed. The composite retained 81% of its specific capacitance after 9000 cycles, increasing it by 46% over ZC MOF and 5.6‐fold over i‐MBene. At 2 mV/s, the asymmetric ZC‐MYB/AC device produced 73.4 F/g.
