Hi all,
I have given a specified dynamics (SD) simulation using internally generated 3 hour meteorological data produced by another cesm simulation.
In its default form SD compsets use Merra2 meteorological files with bnd_topo =
fv_0.9x1.25_nc3000_Nsw042_Nrs008_Co060_Fi001_ZR_sgh30_24km_GRNL_MERRA2_c171218.nc
a. The bnd_topo file also has a PHIS value.Exactly what does bnd_topo file do (I understand its related to topography)?
b. And since i am using the internally generated 3 hour meteorological data of Cesm, which file do i use for bnd_topo?If i do not mention this change in user_nl_cam,it picks up the Merra2 bnd_topo file only (mentioned above).
c. Also in which of the component output log files should i see its use.I could not find its mention in any of the log files.So i am getting no clues.
Kindly help me out.

Thanks,
Anuishree
