Muscle fatigue in patients with severe long COVID: A 2‐year follow‐up study

open access: yesPM&R, EarlyView.
Abstract Background Fatigue is recognized as one of the most persistent and debilitating symptoms of long COVID, affecting both functionality and quality of life. However, its long‐term effects, especially beyond the first year after infection, remain poorly understood.

Spatial observation‐error correlations for AMSU‐A in all‐sky assimilation: An ECMWF and UK Met Office intercomparison

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Assimilation of AMSU‐A all‐sky observations can be increased up to fivefold if spatial observation‐error correlations are accounted for properly. New correlation estimates derived using data from ECMWF and the UK Met Office reveal that correlation length‐scales are between 75 and 150 km for AMSU‐A channels peaking in the troposphere. This is attributed

Using microwave imager observations to improve the ocean temperature in a coupled NWP system

open access: yesQuarterly 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

open access: yesQuarterly 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

Evaluation and assimilation of Arctic Weather Satellite data in the AROME‐Arctic forecast system

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
The Arctic Weather Satellite (AWS), launched in August 2024, is a prototype for the future EPS–Sterna constellation of small satellites carrying an innovative microwave sounder. We present the first assessment of AWS in the regional AROME‐Arctic numerical weather prediction system, covering post‐launch calibration results and the impact of AWS ...

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

open access: yesQuarterly 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 ...

Improving heavy precipitation forecasts through phase‐aware nonlinear bias correction of all‐sky infrared radiances using cloud top temperature differences

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This study proposes a phase‐aware bias correction framework for all‐sky infrared radiance assimilation. Cloud top temperature differences between observations and model background fields are used to identify cloud‐phase mismatch and cold‐cloud regimes.

A review of empirical dam breach models

open access: yesRiver, EarlyView.
Abstract Dam breach modelling is central to flood risk assessment, yet the empirical models commonly used for estimating breach parameters display considerable variability and uncertainty. This review evaluates the performance of widely applied empirical dam breach models and identifies those that consistently show lower uncertainty, such as the ...

From Attitudes to Science Identity: A Critique of the Science Identity Construct in the PISA 2025 Science Framework

open access: yesScience Education, EarlyView.
ABSTRACT Science identity (SI) has gained increasing prominence in science education research due to its potential role in fostering student engagement, motivation, and persistence in STEM pathways. However, its conceptualization remains varied and contested, complicating both measurement and curricular implementation.
