CGD links knowledge across a wide variety of disciplines, natural and social sciences, primarily through CGD's interdisciplinary sections. This multi-faceted scientific knowledge is reflected in CGD's ability to tackle difficult science issues from a variety of perspectives.

CESM | Community Earth System Model is a true community effort including collaboration with scientists from universities, national laboratories, and other research organizations to develop, continuously improve and support the scientific use of a comprehensive Earth modeling system.

ARTMIP | Atmospheric River Tracking Method Intercomparison Project goal is to understand and quantify uncertainties in atmospheric river (AR) science based on choice of detection/tracking methodology.

CATALYST | Cooperative Agreement To Analyze variabiLity, change and predictabilitY in the earth SysTem is the NCAR-DOE cooperative agreement. This group encompasses climate change research, CMIP simulations and multi-model analysis, a hierarchy of models of varying complexity and studies of climate change and variability on multiple timescales.

CHSP | Climate & Human Systems Project is focused on improving understanding of the climate change issue by better integrating research on both human and earth systems.

CMIP | Coupled Model Intercomparison Projects is the analog of AMIP for global coupled ocean-atmosphere general circulation models. CMIP began in 1995 under the auspices of the Working Group on Coupled Modelling (WGCM) which is in turn under auspices of CLIVAR and the Joint Scientific Committee for the World Climate Research Programme (WCRP)

CT-ROMS | Coral Triangle Regional Ocean Modeling System examines how oceanographic conditions shape benthic marine ecosystems in the Coral Triangle, and determines how changes in these conditions will influence those ecosystems in the 21st Century. During this first phase of the project, our immediate goal is to examine how spatial and temporal patterns of coral bleaching within the Coral Triangle will change over the 21st Century, with a better understanding of the physical and biological mechanisms driving those changes.

DOE/UCAR Cooperative Agreement: supports fundamental climate and climate change research related to understanding present/future climate change and improving the simulation of the Earth’s climate system.

GMRC | Geoengineering Modeling Research Consortium identifies and prioritizes critical research gaps in climate modeling with specific significance to geoengineering.

ICONICS | International Committee On New Integrated Climate change assessment Scenarios aims to organize the process of developing new socioeconomic scenarios to facilitate interdisciplinary research and assessment on climate change mitigation and adaptation.

MARBL | Marine Biogeochemistry Library is a modular biogeochemical modeling suite for next-generation ocean models. This project is developing an Oceanic General Circulation Model (OGCM) independent library for the simulation of marine ecosystems and biogeochemical cycles. The objective is to produce a flexible ocean biogeochemical modeling (OBM) tool that will facilitate research on a range of scientific questions.

YOTC | Year of Tropical Convection examines the realistic representation of tropical convection in our global atmospheric models which is a long-standing grand challenge for numerical weather forecasts and global climate predictions. This effort is intended to exploit the vast amounts of existing and emerging observations, the expanding computational resources and the development of new, high-resolution modeling frameworks, with the objective of advancing the characterization, diagnosis, modeling, parameterization and prediction of multi-scale convective/dynamic interactions, including the two-way interaction between tropical and extra-tropical weather/climate.
