14.4.1 Time and date

Namelist /ictime/

These variables are for use setting the time and date for initial conditions, referencing diagnostic calculations, and related items.

•  year0 = year of initial conditions (integer).
•  month0 = month of initial conditions (integer).
•  day0 = day of initial conditions (integer).
•  hour0 = hour of initial conditions (integer).
•  min0 = minute of initial conditions (integer).
•  sec0 = second of initial conditions (integer).

•  ryear = user specified reference year (integer).
•  rmonth = user specified reference month (integer).
•  rday = user specified reference day (integer).
•  rhour = user specified reference hour (integer).
•  rmin = user specified reference min (integer).
•  rsec = user specified reference sec (integer).

•  refrun = Boolean used to specify that the time and date to be used for calculating diagnostic switches is the starting time and date of each submitted job. For example, suppose each job submission integrates for one month starting at the beginning of a month but the number of days per month changes. Setting ``refrun'' = true and setting ``timavgint'' = (days in month)/3 will give 3 averaged outputs per month at intervals of approximately 10 days each. The averaging period timavgper may be set less than timavgint for shorter averages but the output is still every timavgint days. The only restriction is that ``timavgint'' divided into the integration time for each job should work out to be an integral number (because this diagnostic is an average over time). If not, then ``timavgint'' is reset internally to insure this condition.

•  refinit = Boolean used to specify that the time and date to be used for calculating diagnostic switches is the time and date of the initial conditions. For example, if term balances are desired every 20 days ``trmbint'' = 20.0, then they will be calculated and written out every 20 days starting from initial condition time.

•  refuser = Boolean used to specify that the time and date to be used for calculating diagnostic switches is a user specified time and date given by (ryear, rmonth, rday, rhour, rmin, rsec) described above.for comparing diagnostics from various experiments with different initial condition times, refuser =  true is appropriate. Note that setting refuser =  true and choosing the reference time to be the initial condition time is the same as specifying refinit =  true.

  Note that one of these reference time Booleans must be set true and the other two set false.

•  eqyear = Boolean which forces all years to have the same number of days (no leap years). If false, then a Julian calendar is used.

•  eqmon = Boolean which forces all months to have the same number of days. If false, then the actual number of days per month will be used. This is only used when eqyear is true.

•  monlen = the length of each month in days when eqmon = true.
