+
+Generating Climate Patterns from CMIP6 Models
+=============================================
+
+Overview
+--------
+
+The recipe recipe_climate_patterns generates climate patterns from CMIP6 model
+datasets.
+
+.. note::
+  The regrid setting in the recipe is set to a 2.5x3.75 grid. This is done to
+  match the current resolution in the IMOGEN-JULES model, but can be
+  adjusted with no issues for a finer/coarser patterns grid.
+
+
+Available recipes and diagnostics
+---------------------------------
+
+Recipes are stored in esmvaltool/recipes/
+
+* recipe_climate_patterns.yml
+
+Diagnostics are stored in esmvaltool/diag_scripts/climate_patterns/
+
+* climate_patterns.py: generates climate patterns from input datasets
+* sub_functions.py: set of sub functions to assist with driving scripts
+* plotting.py: contains all plotting functions for driving scripts
+
