C o This routine initialises the calendar according to the user |
| 12 |
C specifications in "data.calendar". |

C started: Christian Eckert eckert@mit.edu 30-Jun-1999 |
| 15 |
C changed: Christian Eckert eckert@mit.edu 29-Dec-1999 |
| 16 |
C - restructured the original version in order to have a |
| 17 |
C better interface to the MITgcmUV. |

| 19 |
C Christian Eckert eckert@mit.edu 10-Jan-2000 |
| 20 |
C - Modified namelist input. The data file is first copied |
| 21 |
C to scrunit1 with the comment lines being left out. |
| 22 |
C After this, scrunit1 is used to read the namelist data. |

C Christian Eckert eckert@mit.edu 19-Jan-2000 |
| 25 |
C - Changed the role of the routine arguments. Chris Hill |
| 26 |
C proposed to make the calendar less "invasive". The tool |
| 27 |
C now assumes that the MITgcmUV already provides an ade- |
| 28 |
C quate set of time stepping parameters. The calendar |
| 29 |
C only associates a date with the given starttime of the |
| 30 |
C numerical model. startdate corresponds to zero start- |
| 31 |
C time. So, given niter0 or startdate .ne. zero the actual |
| 32 |
C startdate of the current integration is shifted by the |
| 33 |
C time interval correponding to niter0, startdate respec- |
| 34 |
C tively. |

C Christian Eckert eckert@mit.edu 03-Feb-2000 |
| 37 |
C - Introduced new routine and function names, cal_<NAME>, |
| 38 |
C for verion 0.1.3. |
