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

c changed: Christian Eckert eckert@mit.edu 29-Dec-1999 |
| 18 |
|
|
c |
| 19 |
|
|
c - restructured the original version in order to have a |
| 20 |
|
|
c better interface to the MITgcmUV. |

|
|
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. |

|
|
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. |
