Projects
CVDP
The CVDP is a metrics package that documents the major modes of Earth system variability in models and observations, including ENSO, Pacific Decadal Oscillation, Atlantic Multi-decadal Oscillation, Northern and Southern Annular Modes, North Atlantic Oscillation, Pacific North and South American teleconnection patterns. Time series, spatial patterns and power spectra are displayed graphically via webpages and saved as NetCDF files for later use. Documentation is provided for all calculations. The CVDP can be run on any set of model simulations from any modeling center (as long as the files meet CMIP5 or CMIP6 output metadata requirements), allowing inter-model comparisons..
Coupled Model Intercomparison Project (CMIP)
The objective of the Coupled Model Intercomparison Project (CMIP) is to better understand past, present and future changes arising from either natural, unforced variability or in response to changes in radiative forcing in a multi-model context.
This understanding includes assessments of model performance during the historical period and quantifications of the causes of the spread in future projections. Idealized experiments are also used to increase understanding of the model responses. In addition to these long time scale responses, experiments are performed to investigate the predictability of the Earth system on various time and space scales as well as making predictions from observed Earth system states.
An important part of CMIP is to make the multi-model output publicly available in a standardized format.

Earth System Modeling Program (EaSM)
The Earth System Modeling (EaSM) Program supports the development of innovative Earth system modeling capabilities, with the ultimate goal of providing accurate and computationally advanced representations of the fully coupled and integrated Earth system, as needed for energy and related sectoral infrastructure planning.
Key examples of critical information for energy include accurate projections of water availability, drought incidence and persistence, temperature extremes including prolonged heat stress, probability of storms, opening of the Arctic Ocean, and sea level and storm-surge at coastal regions.
In order to provide this information, considerable effort is needed to develop optimal-fidelity Earth system simulations, with suitably-accurate representation of atmospheric dynamics, clouds and chemistry, ocean circulation and biogeochemistry, land biogeochemistry and hydrology, sea-ice and dynamic land-ice, and in each case including elements of human activities that affect these systems such as water management and land-use.
