MODULE period_accumulator_vars

! The purpose of the derived-type "accumulator" variables is to
! keep track of selected variable values over a specified period
! of time.  This may include summation, running average, beginning
! period value, median, last period value, etc.

! Once the "accumulator" variable has been "filled" after reaching
! the end of it's specified period, the value is passed on to the
! selected period storage variables for each particular parameter.
