Initial Conditions for UFS-Aerosols

Initial Conditions for Prototype 7

Atmosphere

• Step 1:

  • Document from Bing on how GEFS IC were created using above document
  • Document from Shan on making fractional grid ICs
  • Document from Shan on creating oro data

• Step 2:

  • Document from Mike on Noah-MP land model spin-up In each INPUT directory by date, the gfs_data.tile*.nc are the output from Step 1 and the sfc_data.tile*.nc are the output from Step 2 (Note, that Step 2 uses the sfc_* files from Step 1 and then replaces soil temperature, moisture and liquid). The atm ICs are stored by date on hera here: /scratch2/NCEPDEV/climate/climpara/S2S/IC/GEFSwithNOAHMP

Ocean

ICs were created by Travis Sluka using a 3D var. Yan Xue’s overview presentation of 3Dvar (Same ICs used from P2 on)

Ice

Created from CPC ice analysis (Used from P3.0 on, see the procedure on how to generate them)

Waves

New ICs were created based on offline standalone wave runs forced by GEFS. (This document describes how ICs were created for CFSR but needs updating for GEFS)

Other locations for initial conditions

Target P7.1 configuration

On Hera:

ATM:  /scratch2/NCEPDEV/climate/climpara/S2S/IC/GEFSwithNOAHMP
ICE:  /scratch2/NCEPDEV/climate/climpara/S2S/IC/CPC
OCN:  /scratch2/NCEPDEV/climate/climpara/S2S/IC/CPC3Dvar
WAV:  /scratch2/NCEPDEV/climate/climpara/S2S/IC/GEFSwave20210528

These paths are used in the prototype7.1.yaml case file, found in branch feature/p7.1 of the global workflow.
