Dec 10, 2020 · A new atmospheric chemistry-climate model (AM4.1) has been developed as part of GFDL’s fourth-generation suite. AM4.1 includes an advanced dynamical core and physical parameterizations, with enhanced vertical resolution and …

Jan 28, 2025 · The Atmospheric Chemistry and Climate Model Intercomparison Project attempts to meet these various needs through a set of coordinated simulations, diagnostics and evaluations.

May 8, 2023 · This study looks at how the atmosphere responds to the 11-year solar cycle with two state-of-the-art chemistry-climate models (CCMs): the 3-D GEOSCCM and the GSFC 2-D coupled model, and explains why GCMs without coupled chemistry underestimate the temperature response to the solar cycle.

The Atmospheric Chemistry and Climate Model Intercomparison Project (ACCMIP) consists of a series of time slice experiments targeting the long-term changes in atmospheric composition between 1850 and 2100, with the goal of documenting composition changes and the associated radiative forcing.

To address the issues, the joint IGAC/SPARC Chemistry-Climate Model Initiative (CCMI) was established to coordinate future (and to some extent existing) IGAC and SPARC chemistry-climate model evaluation and associated modeling activities.

GFDL’s CM4 consists of AM4 atmosphere at approximately 1 o resolution with 33 levels and sufficient chemistry to simulate aerosols (including aerosol indirect effect) from precursor emissions; OM4 MOM6 -based ocean at 1/4 o resolution with 75 levels using hybrid pressure/isopycnal vertical coordinate; SIS2 sea ice with radiative transfer and C-g...

To gauge the overall effect of complex interactions among emissions, atmospheric chemistry, and climate, we have conducted a series of simulations on 120-year time scales, using a global coupled chemistry-climate model along with various predictions of anthropogenic emissions and different assumptions for chemistry and climate model parameters.

May 20, 2024 · Scientists at GFDL have developed a novel variable-resolution global chemistry-climate model, known as AM4VR, for research at the nexus of U.S. climate and air quality extremes.

The Whole Atmosphere Community Climate Model (WACCM) is a comprehensive numerical model, spanning the range of altitude from the Earth's surface to the thermosphere.

ACOM builds, critically evaluates and applies process, regional- and global-scale models that address atmospheric chemistry research questions, with a focus on couplings between different components of the Earth system (water cycle, biosphere, cryosphere).
