extended scenarios in CESM2

[l_vankampenhout@uu_nl]

Hello,
I was wondering, are extended scenario runs (beyond 2100) for CESM2 already possible, similar to the ECP scenarios in CESM1(CAM5)? If not, are these on the roadmap?

Best,
Leo

There are two runs in the CMIP6 archive of extensions beyond 2100, both with the WACCM configuration, an SSP5.34 overshoot and an SSP5.85, with an SSP1.26 extension coming soon.

I'll check and see if we'll be running CAM6 configurations of these runs.

Thanks Gary! Would you know the casenames for these WACCM runs, so I can take a look? For our application, we'd be mostly interested in extended CAM simulations.

In case it's of interest, Charlie Koven will be giving a talk on CESM2 extensions to 2300 at the LMWG meeting Feb. 23: https://www.cesm.ucar.edu/events/wg-meetings/2021/land.html
