Biomass Burning in Australia: No Evidence for Carbonyl Sulfide (OCS) Enhancement in Fire Plumes From In‐Situ Measurements During SouthTRAC

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Determining the atmospheric abundance and the emission sources of carbonyl sulfide (OCS) plays a crucial role for the sulfur budget in the atmosphere. In addition to its main anthropogenic and biogenic sources, biomass burning is assumed to be an essential, but not well constrained source of OCS.

Aqueous‐Phase Processing of Organic Aerosols at the Southern Great Plains: Insights From Integrated Chemical and Microphysical Analyses

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Aqueous‐phase reactions are hypothesized to be a major pathway for secondary organic aerosol (SOA) formation in humid, cloud‐influenced environments, yet direct observational constraints remain limited. Here we investigated aqueous SOA (aqSOA) formation and evolution during the spring 2016 Holistic Interactions of Shallow Clouds, Aerosols, and

Angular distribution of upwelling artificial light in Europe as observed by Suomi–NPP satellite

Journal of Quantitative Spectroscopy and Radiative Transfer, 2020
Abstract Measuring the angular distribution of upwelling artificial light is important for modeling light pollution, because the direction of emission affects how light propagates in the atmosphere. We characterize the angular distributions of upwelling artificial light for Europe and northern Africa in 2018, based on night time radiance data for ...

Coupled observation‐operator approximations in outer‐loop coupling data assimilation

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 780, October 2026 Part A.
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

Microbial Respiration Across Subtropical Eddies: Submesoscale Variability and Biogeochemical Drivers

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract Island‐induced eddies from the Canary Islands region propagate southwestward along the Canary Eddy Corridor, exporting biological and biogeochemical properties to the oligotrophic open ocean. However, their contribution to organic matter remineralization, and consequently to the biological carbon pump, throughout their life cycle remains ...
