Evaluation of high‐resolution regional CO2 data assimilation–forecast system in East Asia using observing system simulation experiment and effect of observation network on simulated CO2 concentrations

open access: yesQuarterly Journal of the Royal Meteorological Society, Volume 151, Issue 770, July 2025 Part A.
Develop data assimilation (DA)–forecast system: a system was developed to assimilate surface CO2 concentrations to improve atmospheric CO2 concentration simulations in East Asia. Conduct observing system simulation experiments (OSSEs) and verify stability: OSSEs conducted for January and July 2019 showed that DA reduced the bias and root‐mean‐squared ...

A simple framework for assessing the trade-off between the climate impact of aviation carbon dioxide emissions and contrails for a single flight [PDF]

open access: yes, 2014
Persistent contrails are an important climate impact of aviation which could potentially be reduced by re-routing aircraft to avoid contrailing; however this generally increases both the flight length and its corresponding CO emissions.

Transient Darkening of Low‐Level Liquid Clouds by the 2022 Hunga Lamb Wave Observed in GOES‐R Imagery

open access: yesGeophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract The 15 January 2022 eruption of the Hunga volcano generated a Lamb wave, a global atmospheric pressure perturbation which propagates purely horizontally at the speed of sound. Far‐field observations of the daytime passage of the Lamb wave by the Geostationary Operational Environmental Satellite‐R (GOES‐R) series, revealed unexpected ...

On the Potential Role of Lubrication Oil Particles in Contrail Formation for Kerosene and Hydrogen Combustion

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 12, 28 June 2025.
Abstract The radiative forcing caused by contrail cirrus is nonlinearly influenced by the number of ice crystals formed in the exhaust plume behind an aircraft engine. This ice crystal number strongly depends on the properties (number, size, and solubility) of condensation nuclei in the plume available for droplet activation with subsequent freezing ...

Climate change creativity for cirrus clouds and contrails control [PDF]

open access: yes, 2015
Cirrus ice clouds formed normally in the upper troposphere and contrails, shed by aircraft, impact climate and global warming due to prevailing cirrus clouds ice water content and crystal size.

Persistent Elevated Black Carbon Aerosol Layers in the Upper Troposphere and Its Linkage to Aircraft Emissions

open access: yesGeophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
Abstract Altitude profiles of the mass concentrations of aerosol black carbon (BC) have been obtained,up to an altitude of 12 km, from in situ measurements over Hyderabad (17.47°N, 78.57°E, 557 m amsl;a tropical station in the central Indian peninsula), using three successive high altitude balloon ascents during winter and early summer seasons of 2023 ...

Stratospheric aircraft exhaust plume and wake chemistry studies [PDF]

open access: yes
This report documents progress to date in an ongoing study to analyze and model emissions leaving a proposed High Speed Civil Transport (HSCT) from when the exhaust gases leave the engine until they are deposited at atmospheric scales in the stratosphere.
