+description: 'Daily global sea ice concentration climate data record (product ID: OSI-450-a and OSI-430-a) for the preiod 1990-2021 interpolated onto a global regular grid with a resolution of 0.25 degrees'

+# The recipes section tells Pangeo Cloud where to find the recipes within your PR.
+# Many recipe PRs will have just 1 recipe, in which case this section will look similar to the example below.
+# If your PR contains multiple recipes, you may add additional elements to the list below.

+    # The `object` below tells Pangeo Cloud specifically where your recipe instance(s) are located and uses the format <filename>:<object_name>
+    # <filename> is name of .py file where the Python recipe object is defined.
+    # For example, if <filename> is given as "recipe", Pangeo Cloud will expect a file named `recipe.py` to exist in your PR.
+    # <object_name> is the name of the recipe object (i.e. Python class instance) _within_ the specified file.
+    # For example, if you have defined `recipe = XarrayZarrRecipe(...)` within a file named `recipe.py`, then your  `object` below would be `"recipe:recipe"`
