+  **CMORization as a fix.** As of early 2020, we've started implementing cmorization as
+  *fixes*. As compared to the workflow described below, this has the advantage that
+  the user does not need to store a duplicate (CMORized) copy of the data. Instead, the
+  CMORization is performed 'on the fly' when running a recipe. **ERA5** is the first dataset
+  for which this 'CMORization on the fly' is supported. For more information about fixes,
+  see: :ref:`fixing data <esmvalcore:fixing_data>`
