Nitrate Availability Modulates the Temperature Sensitivity of N2O and N2 Production From Denitrification

Global Change Biology, Volume 32, Issue 3, March 2026.
N2O is a potent greenhouse gas with denitrification in sediments and soils representing a major source, yet its response to warming under varying nitrate conditions remains poorly constrained. Combining meta‐analysis with isotope labelling experiments, we show that under nitrate‐replete conditions, warming increases production of climate‐benign N2 ...

Synthesis of Global Soil‐Emitted N2O Isotopic Signatures: Geoclimatic Patterns and Influential Factors

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Nitrous oxide (N2O) is a potent greenhouse gas and major driver of stratospheric ozone depletion. Isotopic data constrain bottom‐up models, yet global natural‐abundance patterns remain poorly resolved. We compiled a global database of in situ soil‐emitted N2O isotopes from chamber‐ or probe‐based studies to examine the spatiotemporal ...

Deep Convection‐Driven Downward Transport of Trace Gases and Aerosols From the Free Troposphere to the Boundary Layer

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Deep convective clouds regulate Earth's energy and moisture budgets, yet their impact on the atmospheric boundary layer (BL) composition remains underexplored. Using long‐term observations from three mid‐latitude sites, we show that deep convection (DC) consistently enhances nighttime surface ozone and is often accompanied by modest increases ...

Corona Discharges Glow on Trees Under Thunderstorms

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Coronae, which are weak electrical discharges, have long been hypothesized to form on trees under thunderstorms, though never directly observed, characterized, or quantified. Using a newly developed instrument that measures ultraviolet emissions from coronae, the first direct observations and quantifications of coronae are presented for two ...

High Ozone Isotope Anomaly at Mt. Everest Linked to Stratospheric Ozone Intrusion

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Atmospheric O3 possesses a rare isotopic signal, that is, Δ17O(O3), varying with pressure and temperature, providing a potential tracer to explore stratosphere‐to‐troposphere transport (STT) of O3 that plays a vital role in atmospheric chemistry and climate.

Kernel‐Based Estimation of Stratospheric Aerosol Radiative Effects From Volcanic and Wildfire Events

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract To facilitate the quantification of the stratospheric aerosol direct radiative effect (ARE), this study develops a suite of aerosol kernels based on Modern‐Era Retrospective Analysis for Research and Applications, Version 2 reanalysis data. The kernels comprise a five‐dimensional data set that includes latitude, longitude, time, wavelength ...

Hydroxyl Interannual Variability Impacts Estimation of Regional Methane Emissions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract Methane is a major greenhouse gas in the Earth's atmosphere, but understanding of its sources and removal budget remains incomplete. Using MIROC4‐ACTM inverse model simulations, we examine the impact of hydroxyl (OH) variation on global and regional CH4 budgets from 2001 to 2019.
