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:

/g/data/ua6/CESM1-CAM5-BGC-LE/<experiment>/<frequency>/<realm>/<mip_table>/<ensemble>/<variable>/<version>/<files>

For example:
