Re: about NRREC

Hi all, When I give NRREC value to -1 then it is running freshly i.e., from the first time step onwards. :?: This actually happens if you set NRREC=1. NRREC=-1 means restart from the latest available field in the ININAME file. I didn't experience any weird behaviour on this using both ROMS-2.1 and ...

Tide_start is not necessarily equal to dstart, while you should use the same convention.
Tide_start represent the reference time you used in the estimates of Ephase when creating tidal_frc.nc (or whatever you have as tidal forcing file).

roms_tools

Hi,
seek for "roms_tools" and download it. There is a GUI ("Visualization tool") that allows you to do pretty much everything. In addition, you can get inspiration looking there and there amongst subroutines if you want to build your own scripts.

you need to define TS_PSOURCE for salinity and/or temperature sources/sinks and/or UV_PSOURCE for mass sources/sinks due to river runoff. You can either add discharge data analytically (in analytical.F) or writing a full NetCDF forcing file. You can find examples on how to write such a river forcing...

time origin in tidal phase calculation

In clm_tides.F, omega is estimated in this way: omega=2.0_r8*pi*time(ng)/Tperiod(itide) time(ng) is the "ocean_time", that is, non necessarily zero (especially in realistic application) at the zeroeth timestep. Ephase should be referenced to the value of "ocean_time" = 0. However...

RAMP in clm_tides.F

Well, this is not a *real* bug. However, in the "official" downloadable ROMS tar file, the time ramping parameter in clm_tides.F has a default value not equal to 1. While the default setting ramp=tanh (tdays(ng)-dstart)/1) may be fine for spinning up at rest, it can be misleading when doin...
