Global data set of biogenic VOC emissions calculated by the MEGAN model over the last 30 years
Abstract. The Model of Emissions of Gases and Aerosols from Nature (MEGANv2.1) together with the Modern-Era Retrospective Analysis for Research and Applications (MERRA) meteorological fields were
CAM-chem: description and evaluation of interactive atmospheric chemistry in the Community Earth System Model
Abstract. We discuss and evaluate the representation of atmospheric chemistry in the global Community Atmosphere Model (CAM) version 4, the atmospheric component of the Community Earth System Model
Pre-industrial to end 21st century projections of tropospheric ozone from the Atmospheric Chemistry and Climate Model Intercomparison Project (ACCMIP)
Abstract. Present day tropospheric ozone and its changes between 1850 and 2100 are considered, analysing 15 global models that participated in the Atmospheric Chemistry and Climate Model
An overview of geoengineering of climate using stratospheric sulphate aerosols
An overview of geoengineering by stratospheric sulphate aerosols is provided, summarizing the past 30 years of work, highlighting some very recent studies using climate models, and discussing methods used to deliver sulphur species to the stratosphere.
Overview of IGAC/SPARC Chemistry-Climate Model Initiative (CCMI) Community Simulations in Support of Upcoming Ozone and Climate Assessments
The workshop participants recommended the creation of a joint IGAC/SPARC Chemistry-Climate Model Initiative (CCMI) to coordinate future (and to some extent existing) IGAC and SPARC chemistry-climate
The Community Earth System Model Version 2 (CESM2)
An overview of the Community Earth System Model Version 2 (CESM2) is provided, including a discussion of the challenges encountered during its development and how they were addressed. In addition, an
Estimating the climate significance of halogen-driven ozone loss in the tropical marine troposphere
Abstract. We have integrated observations of tropospheric ozone, very short-lived (VSL) halocarbons and reactive iodine and bromine species from a wide variety of tropical data sources with the
Bromine and iodine chemistry in a global chemistry-climate model: description and evaluation of very short-lived oceanic sources
The global chemistry-climate model CAM-Chem has been extended to incorporate an expanded bromine and iodine chemistry scheme that includes natural oceanic sources of very short-lived (VSL)
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 Initia- tive (CCMI-1). The CCMI aims to conduct
The Sensitivity of Polar Ozone Depletion to Proposed Geoengineering Schemes
An injection of sulfur large enough to compensate for surface warming caused by the doubling of atmospheric CO2 would strongly increase the extent of Arctic ozone depletion during the present century for cold winters and would cause a considerable delay in the expected recovery of the Antarctic ozone hole.
