b.e30_alpha08b.B1850C_LTso.ne30_t232_wgx3.289

Start by comparing the case directory with the cesm3_0_alpha08b sandbox and the referenced issue 280. Review the listed user_nl_cam, user_nl_clm, and user_nl_mom settings plus BareGroundFluxesMod.F90, then run the case and check the linked diagnostics and output locations for a completed experiment.

Purpose:
Moving to alpha08b + tuning of Leithy + clm bugfix + simone forcing

---

Description:
Same as 280 except

• using alpha08b tag

• add to user_nl_cam
