The CESM Large Ensemble Project is a publically available set of climate model simulations intended for advancing understanding of internal climate variability and climate change. All simulations are performed with the nominal 1-degree latitude/longitude version of the Community Earth System Model version 1 (CESM1) with CAM5.2 as its atmospheric component.

CESM1-CAM5-BGC-LE on raijin

We downloaded a subset of the entire collection, both monthly and daily fields. For each selected variables we downloaded all the available ensembles ??. The data was downloaded from the NCAR | earth system website . The current directory structure mimics the ESGF official DRS and location on raijin is:


For example: /g/data/ua6/CESM1-CAM5-BGC-LE/atmControl/day/atmos/day/r1/psl/v2/
