Update on global ozone: past, present, and future
(World Meteorological Organization, 2014)
This chapter deals with the evolution of global ozone outside of the polar regions. The increase of ozone depleting substance (ODS) concentrations caused the large ozone decline observed from 1980 to the mid- 1990s. Since ...
Formaldehyde in the Tropical Western Pacific: Chemical Sources and Sinks, Convective Transport, and Representation in CAM-Chem and the CCMI Models
©2017. American Geophysical Union. All Rights Reserved. Formaldehyde (HCHO) directly affects the atmospheric oxidative capacity through its effects on HO x . In remote marine environments, such as the tropical western ...
Large-scale tropospheric transport in the Chemistry–Climate Model Initiative (CCMI) simulations
Understanding and modeling the large-scale transport of trace gases and aerosols is important for interpreting past (and projecting future) changes in atmospheric composition. Here we show that there are large differences in ...
No robust evidence of future changes in major stratospheric sudden warmings: a multi-model assessment from CCMI
Major mid-winter stratospheric sudden warmings (SSWs) are the largest instance of wintertime variability in the Arctic stratosphere. Because SSWs are able to cause significant surface weather anomalies on intra-season ...
Tropospheric ozone in CCMI models and Gaussian process emulation to understand biases in the SOCOLv3 chemistry–climate model
Previous multi-model intercomparisons have shown that chemistry–climate models exhibit significant biases in tropospheric ozone compared with observations. We investigate annual-mean tropospheric column ozone in 15 ...
Review of the global models used within phase 1 of the Chemistry-Climate Model Initiative (CCMI)
We present an overview of state-of-the-art chemistry–climate and chemistry transport models that are used within phase 1 of the Chemistry–Climate Model Initiative (CCMI-1). The CCMI aims to conduct a detailed evaluation ...
