  • timeVariableNames (str or list of 2 str, optional) – The name of the time variable (typically 'xtime' or ['xtime_startMonthly', 'xtime_endMonthly']), or None if time does not need to be parsed (and is already in the Time variable)

  • variableList (list of strings, optional) – If present, a list of variables to be included in the data set

  • endDate (startDate,) – If present, the first and last dates to be used in the data set. The time variable is sliced to only include dates within this range.
