+## Sponges
+
+This folder contains tools for creating temperature and salinity sponges for use in MOM6 based on the GLORYS reanalysis.
+
+## preproc_scripts
+
+Scripts to subset, average, and fill the GLORYS data on the uda to preprocess it for the python scripts.
+
+# Regional Subsetting
+
+Regional subsets of the GLORYS reanalysis are created using `ncks` in `get_so_monthly.csh` and `get_thetao_monthly.csh`. 
+You should adjust the regional subset in the script to match the region of interest.
+
+For example:
+```
+ncks -d latitude,40.,90. -d longitude,0.,360 filein.nc fileout.nc
+```
+
+# Scripts
+
+As written these preprocessing scripts must be run in three stages.
+1. First, subset the temperature and salinity and create monthly averages
+```
+sbatch get_thetao_monthly.csh <YEAR> <MONTH>
+sbatch get_so_monthly.csh <YEAR> <MONTH>
+```
+
+2. Next, fill the data
+```
+sbatch fill_glorys_nn_monthly.csh <YEAR> <MONTH>
+```
+
+3. Finally, once the filled data for every month in a given year has been created, the merge script can be used.
+```
+sbatch merge_so_thetao_year.csh <YEAR>
+```
+
+This should produce data that is compatible with `write_nudging_data.py`
+
+## Using these files in MOM6
+
+To use the sponges generated by these scripts in MOM6 we recommend the following settings:
+```
+#override SPONGE = True
+#override SPONGE_UV = False
+#override SPONGE_DAMPING_FILE = "damping_full_t_90d.nc"
+#override SPONGE_IDAMP_VAR = "Idamp"
+#override SPONGE_STATE_FILE = "glorys_sponge_monthly_bnd_${fyear}.nc"
+#override SPONGE_PTEMP_VAR = "thetao"
+#override SPONGE_SALT_VAR = "so"
+#override SPONGE_ETA_VAR = "depth"
+#override INTERPOLATE_SPONGE_TIME_SPACE = True
+#override SPONGE_DATA_ONGRID = True
+```
+These should be added to `MOM_override` in the experiment of the xml.
+
+In the xml, add the paths to the files needed for sponges so that they are include in the `INPUT` directory.
+```
+<!-- Two new files for the nudging: -->
+<dataFile label="input" target="INPUT/" chksum="" size="" timestamp="">
+  <dataSource site="ncrc">$(YOUR_PATH)/damping_full_t_90d.nc</dataSource>
+</dataFile>
+<dataFile label="input" target="INPUT/" chksum="" size="" timestamp="">
+  <dataSource site="ncrc">$(YOUR_PATH)/glorys_sponge_monthly_${fyear}.nc</dataSource>
+</dataFile>
+```
