 ==== How to generate new sea ice initial conditions? ====
+== i00v and i057 ==
+. Fetch ERA-interim atmospheric forcing data
+Go to the cfutools GIT repository (https://earth.bsc.es/gitlab/es/cpg_tools) in the prep_nem_forcings/eraint/orca1 directory
+Follow the instructions from the README. All the scripts to fetch ERA-interim files are in that same directory
+. Prepare wind perturbations and generate members fc1-fc4 for the forcings from member fc0
+Still in the prep_nem_forcings/eraint/orca1 directory from the cfutools GIT repository.
+Instructions in the README and all scripts in that same directory
+. The atmospheric forcing files need to be stored there:
+/esarchive/releases/fg/ocean/eraint
+. Fetch ORAS4 monthly temperature and salinity for the ocean nudging at ECMWF ecgate. Run in the $SCRATCH/scratchdir :
+  #!/bin/ksh
+  EXPID=s4 # Tag of ORAS4 on the ECFS repository
+  DATASOURCE="ec:/emos/OCEA/4/0001/" # Root of the path where to find ORAS4 on ECFS
+  YEARI=2015 # First year to download
+  YEARF=2015 # Last year to download
+  MEMBER_LST="0 1 2 3 4" # List of members to download
+  MON_LST="01 02 03 04 05 06" # List of months to download in formate MM
+  YEAR=$YEARI
+  while [[ $YEAR -le $YEARF ]] ; do
+  for mem in $MEMBER_LST ; do
+    for mon in $MON_LST ; do
+      ecp ${DATASOURCE}/opa${mem}/output/${YEAR}/0001_1m_${YEAR}${mon}01_${YEAR}${mon}*_grid_T_02.nc.gz s4_fc${mem}_${YEAR}${mon}_grid_T.nc.gz
+    done
+  done
+  YEAR=$((YEAR+1))
+  done
+. Download the ORAS4 monthly temperature and salinity locally:
+  cd /esarchive/releases/nudging/ocean/s4/ORCA1
+  ftp ecaccess.ecmwf.int
+  cd ECSCRATCH/scratchdir
+  prompt
+  mget *
+  for ((jmemb=0;jmemb<=4;jmemb++)) ; do mv *fc${jmemb}*gz* fc${jmemb} ; done
+. 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/example
+ edit loop_outputs_oras4.sh
+ change the following arguments:
+ year0=2015 # First year to process
+ yearf=2015 # Last year to process
+ fc0=0 # First member to process
+ fcf=4 # Last member to process
+ Launch on stargate:
+ sbatch loop_outputs_oras4.sh
+. Extend i00v and i057
+For i00v, it is necessary to copy /home/vguemas/autosubmit_i00v and used this autosubmit version. It is also
+necessary to copy at ithaca /scratch/cfu/vguemas/i00v into your scratch. For i057, Autosubmit 2.4 or 2.5 can
+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.
