Toward a More Physical Representation of Convective Gravity Waves in GFDL’s GCM

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.
Abstract We implemented in GFDL's global atmospheric model a parameterization for convective gravity waves, which explicitly describes the wave source based on the latent heating rates from the parameterized deep convection. The characteristics of the simulated Quasi‐Biennial Oscillation (QBO) in the equatorial stratosphere depend on the tunable ...

Variations in surface ozone at Nainital : a high-altitude site in the central Himalayas [PDF]

, 2010
Surface ozone measurements have been made for the first time at Nainital (29.37 degrees N, 79.45 degrees E, 1958 m amsl), a high-altitude site in the central Himalayas, between October 2006 and December 2008.

Ozone and Stratospheric Chemistry

, 2016
The stratosphere is the atmospheric layer comprised between 8–18 km for its lower altitudes and 40–60 km for its upper altitudes, which correspond more or less to the stratospheric ozone layer thickness. In this part of the atmosphere, intense UV radiations from the sun fuel an active and energetic photochemical reactor leading to the formation of two ...

Enhancing the Upper Boundary Layer Damping Scheme for km‐Scale ICON: A Question of Wavelength

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.
Abstract The upper boundary condition treatment in atmospheric models has a pronounced impact on stability and performance. At the same time, the choice of damping settings can severely impact atmospheric states by not sufficiently preventing back‐reflections of vertically propagating waves from the model top or provoking back‐reflections from the ...

Development and Evaluation of the Simplified Tropospheric Chemistry Mechanism T4 in the Community Earth System Model (CESM) for Climate Simulations

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.
Abstract Simulating atmospheric chemistry in Earth system models is critical for climate projections but remains computationally intensive. Comprehensive mechanisms, such as the MOZART‐T1 scheme in the Community Earth System Model (CESM), often limit the feasibility of long‐term or large‐ensemble simulations.

Inside the Fire Plume Chemical Interactions: A Review on Key Processes and Future Directions

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract Fire plumes are rising columns of heated air masses, consisting of gaseous and particulate matter generated by combustion, affecting air quality, climate and public health. The chemical species released undergo secondary reactions and participate in chemical and physical interactions, altering the properties of the fire plume.

Phase Transition of CO2‐Driven Equatorial Pacific Warming Pattern Governed by Ocean Dynamics and Remote Forcing

AGU Advances, Volume 7, Issue 6, September 2026.
Abstract Climate models robustly project an El Niño–like warming under rising CO2, yet recent observations show the opposite with enhanced zonal SST gradients. Whether the long‐term projection is relevant for interpreting historical trends remains questionable.

Ozone Depletion Modulated by Arctic Polar Stratospheric Cloud Types

Geophysical Research Letters
Polar Stratospheric Clouds (PSCs) act as a reaction interface for polar stratospheric ozone depletion. In this study, we analyze the distribution characters of Arctic PSCs from 2006/2007 to 2020/2021, and investigate the impact of PSCs on ozone depletion

Global Ozone Reduction Driven by Dust‐Catalyzed Halogen Chemistry

AGU Advances, Volume 7, Issue 6, September 2026.
Abstract Tropospheric ozone (O3) influences climate and poses risks to human health and crop productivity. Its distribution is shaped by complex interactions between chemical production, transport, and loss processes, including reactions with naturally occurring halogens.
