Option to overwrite runoff with prescribed runoff for certain regions #928
Comments
This does need to be done in the release version. Here's some notes I've found on this from email: A paper on the simulation to compare to... https://agupubs.onlinelibrary.wiley.com/doi/epdf/10.1029/2019MS002031 I think this corresponds to this simulation with Ice Sheet on: b.e21.B1850G.f09_g17_gl4.CMIP6-piControl-withism.001 see https://csegweb.cgd.ucar.edu/experiments/public/ Here's a note from Bill:

Runoff sent to the coupler includes lnd2atmType terms: surface: History terms: QRUNOFF_TO_COUPLER(qflx_rofliq_grc), QRUNOFF_ICE_TO_COUPLER(qflx_rofice_grc) There's a glacier, lake, wetland residual term as well, and the transient land change flux qflx_rofliq_grc comes from qflx_roflig_col which comes from qflx_runoff qflx_runoff: is in HydrologyDrainageMod.F90 |
Looks like this should be a modification of SurfaceRunoff in SoilHydrologyMod.F90. So the namelist items to control the stream files would be in SoilHydReadNML which uses the namelist: soilhydrology_inparm. The streams handling could be additional subroutines part of SoilHydrologyMod.F90. This work is started on my fork on the prescribed_glc_runoff branch. |
Miren V. pointed me to the following in an email:

This work is started and on my prescribed_glc_runoff branch. So |
This is something needed for the TU Delft project. I'm putting it in here partially to see if there might be some interest in it long term.
This is a note from @billsacks on a discussion we had with Miren V. on how to do this.
The namelist control for this would be to turn it on or off, and then also which glacier region(s) to operate over. For present day there are a total of four regions: inland Greenland, outer Greenland and possible ice shelves for Greenland, Antarctica, and everything else.
For the Delft project this needs to go on the release branch.
