CMIP6 CESM2 hindcast (1850-2014) with high-top atmosphere (WACCM6) with interactive chemistry (TSMLT1), interactive land (CLM5), coupled ocean (POP2) with biogeochemistry (MARBL), interactive sea ice (CICE5.1), and non-evolving land ice (CISM2.1)

Simulation of recent past (1850 to 2014). Impose changing conditions (consistent with observations). Should be initialised from a point early enough in the pre-industrial control run to ensure that the end of all the perturbed runs branching from the end of this historical run end before the end of the control. Only one ensemble member is requested but modelling groups are strongly encouraged to submit at least three ensemble members of their CMIP historical simulation. (CMIP6 Experiment).

Users can access the data from the Earth System Grid Federation or Climate Data Gateway as registered users; see the 'Related links' section.

Diagnostic plots are also available from the 'Related links'.

NCAR users may access the data from Glade; path(s) listed in the 'Additional Information' section.

This is the only DASH metadata record for members 001 through 003 of a 3 member ensemble set.
