TL;DR: An overview of the MERRA-2 system and various performance metrics is provided, including the assimilation of aerosol observations, several improvements to the representation of the stratosphere including ozone, and improved representations of cryospheric processes.
The GEOS-5 Data Assimilation System-Documentation of Versions 5.0.1, 5.1.0, and 5.2.0

TL;DR: The GEOS-5 global atmospheric model and data assimilation system (DAS) as discussed by the authors has been developed by NASA for the Modem Era Retrospective analysis for Research and Applications (MERRA).
Journal ArticleDOI

TL;DR: In this article, 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 CCMs.

TL;DR: In this paper, the authors used eleven coupled chemistry-climate models (CCMs) employing nearly identical forcings to project the evolution of stratospheric ozone throughout the 21st century.
Journal ArticleDOI
What would have happened to the ozone layer if chlorofluorocarbons (CFCs) had not been regulated
Paul A. Newman,Luke D. Oman,Anne R. Douglass,Eric L. Fleming,Stacey M. Frith,M. M. Hurwitz,Stephan R. Kawa,Charles H. Jackman,Nickolay A. Krotkov,Eric R. Nash,J. E. Nielsen,Steven Pawson,Richard S. Stolarski,Guus J. M. Velders +13 more
TL;DR: In this paper, the authors used a fully-coupled radiation-chemical-dynamical model to simulate a future world where ODSs were never regulated and ODS production grew at an annual rate of 3%.
