bg.e30_beta08.B1850C_MTso.ne30_t232_wgx3.334.gris2way_init_CLMicase_GLCwithIceCap

Start by reading the related issues 320 and 338, then review the listed case directory, sandbox, output archive, and CISM/CAM/MOM configuration details. The issue records a CESM simulation rather than naming a code change; completion is not defined beyond preserving or validating this run's setup and output.

Purpose:
This simulation is testing the CESM with a fully dynamically evolving Greenland ice sheet with the removing ice cap option turned off.

---

Description:

This is a hybrid run branching from year 73 of https://github.com/NCAR/cesm_dev/issues/320. Prior to running the model, the Greenland ice sheet (GrIS) was initialized following the workflow:

Run an I compset using data atmosphere from run 334 between years 60 and 88.
Spin-up the GrIS for 10,000 years with CISM standalone using coupler history files from the I compset for SMB and temperature.
Use the last time slice of the CISM spinup as CISM input file for this run.

This issue is similar to https://github.com/NCAR/cesm_dev/issues/338 except that the configuration option in CISM remove_ice_caps = .false.
