how to get instantaneous output

Hi,
i am trying to get instantaneous data (especially sensible heat flux and evaporation) but i have a problem that whatever i do, the model gives me monthly averaged output

in my namelist :

hist_dov2xy = .false. (i want only for one grid)
hist_nhtfrq = -1 (for every timestep)
hist_mfilt = 7848 (i want only one output file containing all my data, i have 7848 timesteps)


i used HIST AVGFLAG PERTAPE = I but then the model didnt work
i have also used HIST_FINCL2 = FS:I but it didnt work either(monthly averaged again)

can anyone suggest any solutions for this?

thanks in advance...

Altug,

I see one problem:
hist_nhtfrq = -1
should be
hist_nhtfrq = 1
because the negative sign means "days".

However, the above cannot explain why you got monthly files. Are you possibly starting the simulation as a restart from a simulation that was writing monthly output? I believe that restarts keep everything the same even if you change the namelist.

If so, then you should overcome this problem by pointing to the same restart file but with a branch run. See the corresponding example in the clm user's guide. The branch run will require you to change the case name unless you say that you don't want to with the respective namelist parameter.
