Digitizing collections to unlock the full potential of palynology: A case study with the Smithsonian palynology collection

PLANTS, PEOPLE, PLANET, EarlyView.
Large palynological collections have been built over decades and contain vital information. However, they are often difficult to access and use effectively. What is the point of having such collections if they are not fully utilizable? To solve this problem, we digitized the Smithsonian palynological collection using both light and confocal microscopy.

Digitalising biodiversity: Exploring perceptions on risks and opportunities

PLANTS, PEOPLE, PLANET, EarlyView.
Digitalisation is transforming biodiversity conservation, offering new opportunities for research, governance and public engagement. Herbarium digitisation, for example, enables large‐scale access to plant data, supporting conservation, restoration and sustainable use.

A pilot variational coupled reanalysis based on the CESAM climate model

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Variational data assimilation of in‐situ and satellite ocean data and reanalysis atmospheric data into an intermediate complexity Earth system model is possible by adjusting the surface fluxes and internal model parameters. This pilot application requires nearly complete information on the atmospheric state for synchronization.

Assimilation of European and global Mode‐S aircraft observations into the Met Office global deterministic numerical weather prediction model

Quarterly Journal of the Royal Meteorological Society, EarlyView.
European and global Mode‐S aircraft reports have been assimilated into the Met Office global deterministic numerical weather prediction model, improving forecast accuracy for wind, temperature, and geopotential height. This is the first time global Mode‐S network data have been assimilated, which include data from under‐observed regions, and has ...

All‐sky assimilation impacts of the Tomorrow.io microwave sounder constellation on global weather forecasts

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Key Findings: An assimilation methodology is established for the Tomorrow.io microwave sounder (TMS) flying on CubeSats in sun‐synchronous and inclined orbits, and in all cloud scenes. The TMS has a significant impact on weather forecast lead times up to 3 days in the Tropics in a research‐quality numerical weather prediction setting, and yields water ...

Covariance of the intertropical discontinuity and African easterly jet in Sahelian wet and dry years

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Intertropical discontinuity and African easterly jet (AEJ) positions are strongly correlated, with a more pronounced linear relationship across wet years. Surface heat flux anomalies modify low‐level temperature and sensible heat flux gradients that shift the AEJ core south of the gradient maxima in both composites.

An anatomy of fog over Nova Scotia under a ridge on 8 September 2021

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Image from an aircraft traveling eastward at 1230 UTC (0930 Atlantic Daylight Time, ADT) on 8 September 2021. The view is to the southeast over the eastern coast of Nova Scotia. The leading head of the fog bank is in the image with its base on the sea surface.

The non‐hydrostatic option of the ECMWF global weather forecast model: Improvements for kilometre‐scale modelling

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study presents improvements to the non‐hydrostatic version of the European Centre for Medium‐Range Weather Forecasts (ECMWF) Integrated Forecasting System (IFS), enabling stable global simulations at 1.4‐km resolution. A systematic comparison with the hydrostatic version at resolutions from 9 to 1.4 km shows that non‐hydrostatic effects emerge in ...
