question about SSH

#1 Unread post by nmichelet »

Hello,
I am currently trying to make a simulation with only tidal forcing, but I encounter a problem to calibrate the SSH. It seem to dissipate to much at the end of it and I don't really know what I need to modify. If you can give me an advice it would be really helpfull.
Thanks a lot

DSTART = 34042.0d0 ! days
TIDE_START = 34042.0d0 ! days
I believe the TIDE_START should be zero if your tides origin is the same as the ROMS time origin.

Thanks for your answer Kate but it does not work, I think the two dates are independent. Well to be sure if I put the right date, I want my simulation to begin the 15th of March 1993. So I calculate the number of days between the 1st of January 1900 (my reference time) and this one and put the difference in TIDES_START and DSTART. Is it correct?
