[MITgcm-support] Bulk Force and SSS restoring

[Amato Evan]

Hello Everyone,

I am trying to estimate the effect of surface forcing by volcanic- 
aerosols on tropical SST. To do this I have a 1x1 degree model setup w/ 
23 vertical levels. After spining up the model for 130 years using  
NCEP and WOA data (and SSS restoring), I would like to "turn-on" the  
BULK_FORCE package in order to change downward lw & sw fluxes in  
accordance with volcanic aerosol surface forcing (something I  
calculate offline w/satellite obs. and an RT model).

I am giving the BULK_FORCE pkg wind stress values (calcWindStress  
= .FALSE.), but I would like to run w/surface salinity restoring, and  
not have the model calculate freshwater fluxes using runoff and precip  
input files. My motivation is just to make the model runs complete  
more quickly. What I can't determine from the documentation and source  
code is if I leave:

RainFile= ' ',
RunoffFile= ' ',
EmPFile= ' ',

in data.blk, will bulk_force just restore to surface salinity on the  
time scales I define in "data"? If anyone has experience with this, I  
would really appreciate input. Also, the contents of build/, code/,  
and input/ for my setup can be found here:

If anyone is so inclined to look them over.

Thanks!

Sincerely,
Amato
