v2.0 1deg data

The E3SM version 2 water cycle simulation campaign include standard set of Coupled Model Intercomparison Project Phase 6 (CMIP6) Diagnosis, Evaluation, and Characterization of Klima (DECK) simulations. These E3SM simulations at standard resolution  have been completed and the data is publicly available.

Data Resolution

The standard resolution configuration of E3SM v2.0 water cycle configuration has approximate horizontal resolution of 1 deg latitude by 1 deg longitude in atmosphere (110 km grid spacing),  with ocean and sea ice grid of 60 km in the mid-latitudes and 30 km at the equator and poles, and river transport at 55 km horizontal resolution.

For more details, refer to Coupled E3SM v2 Model Overview or directly to the scientific paper (doi:10.1029/2022MS003156), which documents the E3SM model version 1, its almost 3000 years of DECK simulations and discusses the model’s performance.

The datasets include the following experiments

  • piControl – Pre-industrial control (piControl) simulation (500 years)
  • historical – Historical simulations 1850-2014 (165 years) 5 ensembles
  • 1pctCO2 – Prescribed 1% / year CO2 increase (1pctCO2) simulation (150 years)
  • abrupt-4xCO2 – Abrupt CO2 quadrupling (abrupt-4xCO2) simulation (150 years)
  • amip – atmosphere only AMIP simulation 1870-2014 (145 years) 3 ensembles
