          13             : ! (aligned in a vector), providing a 4th dimension (time). During
          14             : ! emission calculation, only the vector element ('time slice')
          15             : ! representative for the given time will be used. Currently, the
          16             : ! following time slice intervals are supported:
          17             : !
          18             : ! \begin{itemize}
          19             : ! \item Constant: Only one time slice (default)
          20             : ! \item Hourly: Between 2-24 time slices. These slices will be split
          21             : !         into even day bins, and are cycled through accordingly.
          22             : !         the local time is used to obtain the current valid index at
          23             : !         each longitude.
          24             : ! \item Hourly\_gridded: As hourly, but uses the same time slice index
          25             : !         across all longitudes (based upon UTC time).
          26             : ! \item Weekdaily: Seven time slices, representing the days of the
          27             : !         week: Sun, Mon, ..., Sat. Uses local time.
          28             : ! \item Monthly: 12 time slices, representing the months of the year:
          29             : !         Jan, ..., Dec. Uses local time.
          30             : ! \end{itemize}

          32             : ! The time slice cycling frequency is automatically determined during
          33             : ! creation of a data container - based upon the time stamp settings in
          34             : ! the HEMCO configuration file and the time information read from the

          42             : ! taken into account and UTC time is used at all locations to select the
          43             : ! currently valid time slice. The exception is weekdaily data, which is
