Elliptical Orbit Representation for the Annual Evolution of the Northern Hemisphere Stratospheric Polar Vortex. Part I: Diagnosing Interannual Variability

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract Using a single annual frequency with each year defined from July 1 to June 30 of the following calendar year, this study fits an ellipse to the yearly phase space trajectory of the daily time series of MU (stratospheric mass‐weighted zonally integrated zonal wind at 60°N) and M (total polar stratospheric air mass over 60–90°N) to represent the

Elliptical Orbit Representation for the Annual Evolution of the Northern Hemisphere Stratospheric Polar Vortex. Part II: Long‐Lead Forecasts of Wintertime S2S Anomalies

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract In Part I, we represent the annual evolution of the Northern Hemisphere stratospheric polar vortex (SPV) in individual years using an ellipse, defined through six ellipse parameters, for the phase‐space trajectory of the daily time series of MU (mass‐weighted zonally integrated zonal wind at 60°N above 400 K) and M (stratospheric air mass over

Twenty‐One Years of Global Atmospheric Chlorine Inventories From Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE‐FTS) Measurements

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract We present atmospheric chlorine inventories over 21 years (2004–2024) and five latitude bands (82–60°N, 60–30°N, 30°N–30°S, 30–60°S, 60–82°S) across altitudes from the surface up to 61 km. These inventories were calculated using the Atmospheric Chemistry Experiment‐Fourier Transform Spectrometer (ACE‐FTS) version 5.3 retrievals of the volume ...

Ratios of Extinction Coefficient, Mass, and Surface Area to Backscatter Coefficient and Mass to Extinction Coefficient Derived From Balloon‐Borne Stratospheric Aerosol Size Distribution Measurements From 1989–2025

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract In situ measurements of stratospheric aerosol are the only measurements that provide sufficient detail to determine aerosol number, size, surface area, volume/mass, and effective radius; however, these measurements are limited in space and time.

Achieving Net‐Zero in the Electricity Sector in China by 2050 Considering Environmental and Economic Objectives

open access: yesAdvanced Sustainable Systems, Volume 10, Issue 3, March 2026.
China's pathways to net‐zero electricity by 2050 are evaluated using life cycle environmental and economic assessment across six scenarios. Results show that a renewables‐only grid offers the best overall environmental performance and lowest cost, but increases burdens on metal depletion, land use, and ecotoxicity.

Recent Warming of the Southern Hemisphere Subtropical Lower Stratosphere and Antarctic Ozone Healing

open access: yesAGU Advances
Observed temperature changes from 2002 to 2022 reveal a pronounced warming of the Southern Hemisphere (SH) subtropical lower stratosphere, and a cooling of the Antarctic lower stratosphere.
