+"""This module stores definitions for derived variables.

+`DERIVED_VARIABLES` is a dictionary that stores definitions for derived

+keys and attempts to map them to a formula function to calculate a derived
+variable.
+
+For example to derive 'PRECT':
+ 1. In `DERIVED_VARIABLE` there is an entry for 'PRECT'.
+ 2. The netCDF file does not have a 'PRECT' variable, but has the 'PRECC'
+ and 'PRECT' variables.
+ 3. 'PRECC' and 'PRECL' are used to derive `PRECT` by passing the
+ data for these variables to the formula function 'prect()'.
