Interpolation of monthly initial conditions

[chillwx@gmail_com]

I am running CAM3 with a "data ocean model", which requires prescribed monthly SST forcing. Can anyone point me to the file that interpolates the monthly averaged SST boundary conditions to the temporal resolution of the CAM timestep (I think it is 20 minutes for me). So far, my guess is that it is in the "inidat.F90" file in the dynamics/eul directory, but I cannot find the exact code.

In cam3 the sst data is handled by the module sst_data in
models/atm/cam/src/ocnsice/dom/sst_data.F90

Hi Brian,

I want to run CCSM3 in CAM mode (-compset F) with specified daily SST. I see that /ocn/docn6/data_in_mod.F90 reads "multiyear" data but I'm not sure if data at daily frequency is accepted. If the expected frequency is monthly, do you know anyone who has changed the code to allow daily frequency?

Thank you,

Cristiana

I got the following info about docn6 from Brian Kauffman who's one of the developers:

> years) or data for years 10 thru 10 (one whole year).

Thank you for your quick reply!
