Using microwave imager observations to improve the ocean temperature in a coupled NWP system
Quarterly Journal of the Royal Meteorological Society, EarlyView.A recent upgrade to the ECMWF IFS has implemented outer‐loop coupling between the atmosphere and the ocean. This work uses this method to pass ocean skin temperature estimates derived from satellite‐borne microwave imagers to the ocean data assimilation system; the updated ocean state is then passed back to the atmospheric system.

Coupled observation‐operator approximations in outer‐loop coupling data assimilation
Quarterly Journal of the Royal Meteorological Society, EarlyView.We present a methodology for coupled variational data assimilation that allows the effect of coupled observation operators whilst maintaining separate minimisations across model components. This allows us to constrain the atmosphere, ocean, and sea‐ice components of our coupled model directly from satellite radiances. We illustrate the system in action

Journal of Field Robotics, EarlyView.ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Journal of Field Robotics, EarlyView.ABSTRACT Grass mowing is one of the most resource‐consuming activities in green maintenance, whether in private areas such as home gardens or in public spaces like urban parks. In recent years, concerns related to climate change, human health, and sustainability have become increasingly prominent in green maintenance, leading manufacturers and industry

Advanced Physics Research, Volume 5, Issue 8, August 2026.Sintering ZnAl0.1Sn0.1Fe1.8O4 nanoparticles at 1200°C optimizes structural lattice dynamics, significantly enhancing both macroscopic elastic stiffness and high‐frequency dielectric response through synergistic Al3+ stabilization and Sn4+‐driven charge transport. ABSTRACT In this work, ZnAl0.1Sn0.1Fe1.8O4 (ZASFO) ferrites were synthesized via a sol–gel

Damaging Surface Hail in Simulations of Satellite‐Detected Hailstorms in Australia's Tropics
Atmospheric Science Letters, Volume 27, Issue 8, August 2026.Satellite detections of hail signatures are uncertain in the tropics, where the deep troposphere increases the chances that ice detected aloft will melt before it reaches the surface. We used numerical weather simulations to examine the plausibility of damaging surface hail at times and locations when satellites detected hail signatures over Australia ...

Enabling Under Ice Glider Operations: A Backseat Driver Approach
Journal of Field Robotics, Volume 43, Issue 5, Page 3292-3311, August 2026.ABSTRACT Polar Oceans are key locations for forcing global ocean circulation, influencing both global climate and biogeochemical cycles. Due to restricted access to these seasonally and perennially ice‐covered regions, these areas are severely undersampled.

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.Abstract Past evaluation of artificial intelligence (AI) weather prediction has primarily relied on reanalyses, which can obscure important deficiencies due to prevailing biases in reanalyses themselves. Here, we present MAUSAM (Measuring AI Uncertainty during South Asian Monsoon), an evaluation of seven leading AI‐based prediction systems—FourCastNet,

Atmospheric Constituent Data Assimilation in NASA's Goddard Earth Observing System
Earth and Space Science, Volume 13, Issue 8, August 2026.Abstract Many of today's most significant and urgent scientific questions, including those about the impact of human activity on air quality and radiative forcing, require the synthesis of observations of atmospheric constituents and scientific theory.
