CESM2 Large Ensemble Data Sets

Data from the project are publicly available to any scientist who is interested. Annual, monthly, 5-day, daily, 6-hourly and 3-hourly outputs have been saved as single variable timeseries.

A selected list of monthly 100 member ensemble mean climate variables can be accessed through the IBS openDAP server.

For casper users, the data is available on glade at:


Restart files are also available on casper at:


CVDP-LE diagnostics are available from the ICCP Climate Data portal.

Note: 86 of the first 90 ensemble members are complete and available as of early-September 2021. The historical portions of an additional 4 members (1251.011, 1251.012, 1251.016 and 1251.017) are not complete, and ensemble members 91-100 (containing extensive MOAR output) are not yet accessible. We expect that the full 100-member ensemble will be available by mid-October 2021. Upon project completion, 1.8TB of CESM2-LENS data will be available from NCAR's Climate Data Gateway using the links below.
