c o This routine initialises the calendar according to the user |
| 13 |
c specifications in "data.calendar". |
| 14 |
c |

c started: Christian Eckert eckert@mit.edu 30-Jun-1999 |

c |
| 19 |
c - restructured the original version in order to have a |
| 20 |
c better interface to the MITgcmUV. |
| 21 |
c |
| 22 |
c Christian Eckert eckert@mit.edu 10-Jan-2000 |
| 23 |
c |
| 24 |
c - Modified namelist input. The data file is first copied |
| 25 |
c to scrunit1 with the comment lines being left out. |
| 26 |
c After this, scrunit1 is used to read the namelist data. |
| 27 |

c |
| 30 |
c - Changed the role of the routine arguments. Chris Hill |
| 31 |
c proposed to make the calendar less "invasive". The tool |
| 32 |
c now assumes that the MITgcmUV already provides an ade- |
| 33 |
c quate set of time stepping parameters. The calendar |
| 34 |
c only associates a date with the given starttime of the |
| 35 |
c numerical model. startdate corresponds to zero start- |
| 36 |
c time. So, given niter0 or startdate .ne. zero the actual |
| 37 |
c startdate of the current integration is shifted by the |
| 38 |
c time interval correponding to niter0, startdate respec- |
| 39 |
c tively. |
| 40 |
c |

c Christian Eckert eckert@mit.edu 03-Feb-2000 |

c |
| 43 |
c - Introduced new routine and function names, cal_<NAME>, |
| 44 |
c for verion 0.1.3. |
