The climate-chemistry-aerosol-cloud-radiation feedbacks are important processes occurring
in the atmosphere. Accurately simulating those feedbacks requires fully-coupled …

A chemistry-transport model (CTM) intercomparison experiment (TransCom-CH 4) has been
designed to investigate the roles of surface emissions, transport and chemical loss in …

We present a new global three‐dimensional chemical model for the troposphere, named
chemical atmospheric general circulation model (AGCM) for study of atmospheric …

In recent years a number of chemistry-climate models have been developed with an
emphasis on the stratosphere. Such models cover a wide range of time scales of integration …

Methane (CH 4) is an important greenhouse gas and plays a significant role in tropospheric
and stratospheric chemistry. Despite the relevance of methane (CH 4) in human-induced …

Atmospheric methane (CH 4) increased from∼ 900 ppb (parts per billion, or nanomoles per
mole of dry air) in 1900 to∼ 1800 ppb in 2010 at a rate unprecedented in any observational …

Estimates of annual‐mean stratospheric temperature trends over the past twenty years, from
a wide variety of models, are compared both with each other and with the observed cooling …

The hydroxyl radical (OH) is a key oxidant involved in the removal of air pollutants and
greenhouse gases from the atmosphere,,. The ratio of Northern Hemispheric to Southern …

We examine contributions from various source regions to global distributions and budgets of
tropospheric ozone (O3) in the context of intercontinental transport, using tagged tracer …

Methane (CH4) emission reduction to limit warming to 1.5° C can be tracked by analyzing
CH4 concentration and its isotopic composition (δ 13C, δ D) simultaneously. Based on …
