Validation of ECMWF Ensemble Forecasts of Sea Surface Latent and Sensible Heat Fluxes in the Pacific Arctic Against Saildrone Observations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Estimates of sea‐surface latent and sensible heat fluxes using in situ observations are very rare in the Arctic Ocean. Saildrone Explorer uncrewed surface vehicles (saildrones) were deployed in the Bering, Chukchi, and Beaufort Seas from May–October 2019.

The Role of Lightning in Atmospheric Chemistry

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Lightning has important effects on atmospheric constituents in primarily the middle and upper troposphere. We summarize the effects of lightning on atmospheric chemistry that have been published since the last major review in 2007. The estimates of NOx production by lightning (LNOx) are based on five methods: theoretical/laboratory estimates ...

NOx and HCHO in Hot Extremes Observed From Space and Their Influences on Urban Populations: A Case Study in Houston, TX (USA)

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Hot extremes have increased globally and on a regional scale. Traditional data processing methods to understand air quality changes in hot extremes may not adequately describe variations in directly emitted air pollutants like nitrogen oxides (NOx) or volatile organic compounds (VOCs) and their influence on secondary species such as ozone (O3).

Self‐Assembly Enabled Mie‐Scattering in Hematite Nanoplatelet Stacks

Nanophotonics, Volume 15, Issue 16, 26 August 2026.
The spectral evolution during the electrolyte‐induced self‐assembly of 120 × 20 nm hematite nanoplatelets into vertical stacks in aqueous solutions is investigated. Optical simulations and correlative electron microscopy/single particle spectroscopy confirm that a collective magnetic dipole mode develops in the assembling stacks.
