Division Overview Organization Structure Funding Awards Visitors Research, Goals, and Activities
Understanding the Climate System • CGD is an integrator for climate research within NCAR and outside of NCAR, at the national and international levels. • CGD will adopt a systems approach to climate research and explore, with our collaborators, a wide-ranging set of problems in order to understand issues of climate variability, climate predictability and climate change.

Goals Develop a comprehensive understanding of Earth’s Climate System, with the aid of models, observations and theory.
Goals Provide community tools to further our understanding of Earth’s Climate System Atmosphere Sea Ice Land Ocean
Modeling • CCSM • Component Models and Fully Coupled Model • Single Column Atmospheric Physics Model •Diagnostic Models • Model for Atmospheric Transport and Chemistry (MATCH) • Aerosol Data Assimilation •Simplified Mechanistic Models Saravanan’s Simplified Coupled Model Branstator’s Linearized CCM
Future Goals in Modeling(1 of 2) • Comprehensive Diagnostics Capability • Continued Improvement of CCSM • Evolution to Earth System Model
Future Goals in Modeling(2 of 2) Physical System Biogeochemical System Chemical System
Analysis • Reanalysis Studies • Climate Diagnostic Studies • Global Data for Model Evaluation • Field Observations
Future Goals in Analysis • Continued evaluation of analysis products • More integrated analysis of CCSM
Theory • Physically Based Understanding of Modes of Variability • Understanding Predictability of Coupled Systems
Future Goals in Theory • Predictability of Coupled System on Seasonal to Interannual time scales
Tools Community Climate System Model – CCSM-2 Community Atmosphere Model – CAM-2 Community Land Model – CLM-2 Community Ocean Model – COM-2 Community Sea Ice Model – CSIM-2 Improved Coupler
Built for vector/parallel computers Atmosphere: CCM3 Land: Land Surface Model Ocean component: Modular Ocean Model Gent-McWilliams K-Profile Parameterization Sea ice: cavitating fluid rheology, simple thermodynamics Built for scalar/parallel computers Atmosphere: CCM3 Land: Land Surface Model Ocean component: Parallel Ocean Program Horizontal Diffusion Philander-Pacanowski Sea ice: viscous-plastic rheology, simple thermodynamics CSM1 PCM1
Merging of CSM and PCM • Agreement to use the same model components • CSM and PCM lab staff will develop a merged flux coupler that can use both sequential and parallel execution mode of components - ongoing team of NCAR and DOE laboratory involvement • NSF and DOE efforts may use different resolutions
New Projects, Collaborators DOE Scientific Discovery Through Advanced Computing (SciDAC) DOE Laboratories (Los Alamos, Livermore, Oak Ridge, etc.) and NCAR will work on expanding the scientific scope and improving the software engineering of CCSM-2 NASA Earth System Modeling Framework NCAR’s SCD - Lead NCAR’s CGD and MMM, GFDL, NCEP, MIT, GSFC, Univ. of Michigan, ANL, LANL - Participants
Minimum Advanced Research Computing System(Provided by SCD) + Negotiated capability commitments may require installation of additional capacity.
