I have a question about what is default Roms internal unit for wave_time and how can I apply a scale factor to my forcing netcdf wave_time unit.
My forcing netcdf wave_time unit is in hours; I can scan (with ncview) each netcdf variable (Hwave,Lwave,Dwave..) along wave_time dimension for 193 times, one each 0.3 hour. So wave_time dimension has a MIN=0 and a MAX=57.6 hours (=2.4 days).
I assume DT=5 sec and NTIMES=41472
When I run my application, I read in my .log file:
GET_2DFLD - wind-induced wave direction, t = 0.0000
(File: Forcscheve.nc, Rec=0001, Index=1)
(Tmin= 0.0000 Tmax= 57.6000)
(Min = 4.62099675E+00 Max = 4.79593447E+00)
GET_2DFLD - wind-induced significant wave height, t = 0.0000
(File: Forcscheve.nc, Rec=0001, Index=1)
(Tmin= 0.0000 Tmax= 57.6000)
(Min = 2.79368877E-01 Max = 5.38707078E-01)
GET_2DFLD - wind-induced mean wavelength, t = 0.0000
(File: Forcscheve.nc, Rec=0001, Index=1)
(Tmin= 0.0000 Tmax= 57.6000)
(Min = 7.50476694E+00 Max = 2.09574566E+01)
And Roms starts time stepping :
GET_2DFLD - wind-induced wave direction, t = 0.3000
(File: Forcscheve.nc, Rec=0002, Index=2)
(Tmin= 0.0000 Tmax= 57.6000)
(Min = 0.00000000E+00 Max = 4.80181473E+00)

(Min = 0.00000000E+00 Max = 5.45222461E-01)

What's the meaning of t=0.3000?I think it is in day,because Roms reads forcing netcdf file again in timestep:
5183 0.29994 1.622943E-03 4.083678E+01 4.083840E+01 3.148417E+07 0

So Roms doesn't reads my forcing netcdf file every 0.3 hours!Roms reads my forcing file in day,every 0.3 day. Is it true?
But I want that Roms reads my forcing file every 0.3 hour!
I look in varinfo.dat to find wave_time and apply a scale factor,but I don't find it!
What can I do?
Thank for advice!
Michele.
