Ozone Trend Analysis in Natal (5.4°S, 35.4°W, Brazil) Using Multi-Linear Regression and Empirical Decomposition Methods over 22 Years of Observations

Remote Sensing
Ozone plays an important role in the Earth’s atmosphere. It is mainly formed in the tropical stratosphere and is transported by the Brewer–Dobson Circulation to higher latitudes.

Meteorological and Emission Drivers of Compound Heat and Ozone Pollution Episodes in Oklahoma City During Periods Influenced by Atlantic Tropical Cyclones

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Compound heat and ozone (O3) pollution events are widespread and pose significant health risks in urban areas. In the Southern Great Plains (SGP), where heat waves are becoming more frequent and intense, these compound events represent a growing environmental and public health concern, underscoring the need for improved process‐based ...

Assessment of Tropical Cyclones Over the Australian Region From Downscaled CORDEX‐CMIP6 Simulations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Tropical cyclones (TCs) cause major economic losses in Australia due to severe winds and floods; however global climate models (GCMs) are too coarse to properly resolve them. Here, we dynamically downscale ERA5 reanalysis and 16 CMIP6 simulations from 11 GCMs using the Conformal Cubic Atmospheric Model (CCAM) to a ∼10 km resolution over the ...

Wind‐Driven Circulation Feedbacks Offset Tropical Geoengineered Sea Salt Emissions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Using a NOAA Geophysical Fluid Dynamics Laboratory coupled atmosphere–ocean (CM4) comprehensive model, we employ simulations of enhanced, geoengineered sea salt aerosol (SSA) emissions in the tropics to examine the circulation response to idealized marine cloud brightening. Increased tropical SSA emissions cool the deployment region and weaken

Influence of stratospheric airmasses on tropospheric vertical O₃ columns based on GOME (Global Ozone Monitoring Experiment) measurements and backtrajectory calculation over the Pacific [PDF]

Atmospheric Chemistry and Physics, 2004
Satellite based GOME (Global Ozone Measuring experiment) data are used to characterize the amount of tropospheric ozone over the tropical Pacific. Tropospheric ozone was determined from GOME data using the Tropospheric Excess Method (TEM).

Large and increasing stratospheric contribution to tropospheric ozone over East Asia [PDF]

Atmospheric Chemistry and Physics
Severe surface ozone pollution in South Korea and China in May–June is due in part to an elevated background subsiding from the free troposphere (750–350 hPa).

Enhancing Identifiable Variational Autoencoder in the Presence of Missing Values and Auxiliary Covariates for Spatio‐Temporal Ozone Modeling

Environmetrics, Volume 37, Issue 6, September 2026.
ABSTRACT The formation of ground‐level ozone follows complex nonlinear photochemical processes that depend on multiple environmental factors and have strong spatio‐temporal structures. Environmental data used to study these dynamics usually originate from multiple sources, including in situ monitoring stations and satellite observations.

Modeling GHG Emissions Across Selected South Asian Countries Using a Unit Log‐Log Quantile Mixed Model

Environmetrics, Volume 37, Issue 6, September 2026.
ABSTRACT This study examines greenhouse gas (GHG) emissions in South Asian countries by analyzing both their proportion relative to global emissions and total emissions, along with key country‐level determinants. To address the bounded (0‐1) and correlated nature of the GHG proportion, this study proposes a new Bayesian Unit Log‐Log Quantile Mixed ...
