+ | ==== How to generate new sea ice initial conditions? ==== | ||
+ | |||
+ | == i00v and i057 == | ||
+ | |||
+ | 1. Fetch ERA-interim atmospheric forcing data | ||
+ | |||
+ | Go to the cfutools GIT repository (https:// | ||
+ | |||
+ | Follow the instructions from the README. All the scripts to fetch ERA-interim files are in that same directory | ||
+ | |||
+ | 2. Prepare wind perturbations and generate members fc1-fc4 for the forcings from member fc0 | ||
+ | |||
+ | Still in the prep_nem_forcings/ | ||
+ | |||
+ | Instructions in the README and all scripts in that same directory | ||
+ | |||
+ | 3. The atmospheric forcing files need to be stored there: | ||
+ | |||
+ | / | ||
+ | |||
+ | 4. Fetch ORAS4 monthly temperature and salinity for the ocean nudging at ECMWF ecgate. Run in the $SCRATCH/ | ||
+ | |||
+ | #!/bin/ksh | ||
+ | EXPID=s4 # Tag of ORAS4 on the ECFS repository | ||
+ | DATASOURCE=" | ||
+ | YEARI=2015 # First year to download | ||
+ | YEARF=2015 # Last year to download | ||
+ | MEMBER_LST=" | ||
+ | MON_LST=" | ||
+ | YEAR=$YEARI | ||
+ | while [[ $YEAR -le $YEARF ]] ; do | ||
+ | for mem in $MEMBER_LST ; do | ||
+ | for mon in $MON_LST ; do | ||
+ | ecp ${DATASOURCE}/ | ||
+ | done | ||
+ | done | ||
+ | YEAR=$((YEAR+1)) | ||
+ | done | ||
+ | |||
+ | 5. Download the ORAS4 monthly temperature and salinity locally: | ||
+ | |||
+ | cd / | ||
+ | ftp ecaccess.ecmwf.int | ||
+ | cd ECSCRATCH/ | ||
+ | prompt | ||
+ | mget * | ||
+ | for ((jmemb=0; | ||
+ | |||
+ | 6. For i057 only, interpolate + extrapolate vertically and horizontally + fill in empty seas for the ORAS4 nudging files to be usable with EC-Earth3 | ||
+ | |||
+ | Go to the cfutools GIT repository | ||
+ | cd prep_restarts/ | ||
+ | edit loop_outputs_oras4.sh | ||
+ | | ||
+ | |||
+ | | ||
+ | | ||
+ | fc0=0 # First member to process | ||
+ | fcf=4 # Last member to process | ||
+ | |||
+ | | ||
+ | | ||
+ | |||
+ | 7. Extend i00v and i057 | ||
+ | |||
+ | For i00v, it is necessary to copy / | ||
+ | necessary to copy at ithaca / | ||
+ | be used. | ||
+ | |||
+ | For both i00v and i057, the expdef needs to be modified to run only the extension of interest. If any permission | ||
+ | issue arises, you can ask to any IT who has root access to fix these permission issues. | ||
+ | |||
+ | The chunk length is 6 months for both i00v and i057. A change in the chunk length would induce code change in | ||
+ | the template relying on Omar's pluggin for ocean nudging. | ||
