The amended and adjusted Montreal Protocol has continued to reduce emissions and
atmospheric abundances of most controlled ozone-depleting substances. By 2012, the total …

Simulations of the stratosphere from thirteen coupled chemistry‐climate models (CCMs) are
evaluated to provide guidance for the interpretation of ozone predictions made by the same …

Attribution of Antarctic ozone recovery to the Montreal protocol requires evidence that (1)
Antarctic chlorine levels are declining and (2) there is a reduction in ozone depletion in …

The Earth Observing System (EOS) Microwave Limb Sounder (MLS) aboard the Aura
satellite has provided daily global HCl profiles since August 2004. We provide a …

Simulations from eleven coupled chemistry‐climate models (CCMs) employing nearly
identical forcings have been used to project the evolution of stratospheric ozone throughout …

The standard product for BrO is taken from the 640-GHz (Core+ R4A) retrievals. The spectral
signature of BrO in the MLS radiances is very small, leading to a very poor signal-to-noise …

Ozone depletion by chlorofluorocarbons (CFCs) was first proposed by Molina and Rowland
in their 1974 Nature paper. Since that time, the scientific connection between ozone losses …

The Antarctic ozone hole is decreasing in size but this recovery will be affected by
atmospheric variability and any unexpected changes in chlorinated source gas emissions …

The abundance of chlorine in the Earth's atmosphere increased considerably during the
1970s to 1990s, following large emissions of anthropogenic long-lived chlorine-containing …
