CESM Models

CESM1 (CAM5) Large Ensemble Community Project
and Accompanying CVCWG Simulations

The climate simulated by each Large Ensemble member is documented by the new Climate Variability Diagnostics Package (CVDP). This diagnostics package calculates a variety of climate metrics not covered by the individual component diagnostic packages. The CVDP was run over a number of time periods: 1920-2018 | 1979-2018 | 2019-2048 | 2019-2100

Data for all the simulations shown below is available off of the Climate Data Gateway (CDG). For direct CDG links to the data please visit the Data Sets Available to the Community page.
