E3SMv1 (Water Cycle)

The E3SM version 1 water cycle simulation campaign includes the 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 v1.0 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.
