input fields for bulk-NCEP formulation

[zhongyf01@yahoo_com]

Hello there,

I am tying to force the ocean model with external surface heat flux (SHF) and surface fresh water flux (SFWF). For 'bulk-NCEP' formulation, I don't know what's the exact field to input. For example, for surface heat
flux (SHF) forcing, the necessary fields are SST, air temperature, air humidity, downward shortwave radiation, cloud fraction, and
wind speed, but are those variables at surface, or at reference height, or even at exact 10m? Are these input fields obtainable
from ATM history files, like "T/TS/TREFHT, Q/QREFHT, FSDS, CLDTOT/CLOUD, U^2+V^2"? Or some complex formula to get the
input fields?

Thanks.

The 'bulk-NCEP' option for shf_formulation is not a POP option supported by the CCSM project. Running ocean-standalone experiments in the CCSM context (compset "C" integrations) requires use of the 'partially-coupled' option for shf_formulation. This configuration of CCSM3 is unsupported and requires significant expertise to run correctly.

Note that 'bulk-NCEP' results in a call to calc_shf_bulk_ncep. This routine has
parameters which specify the height of the various fields (windspd_height, tair_height, etc). A close examination of this subroutine should answer your questions.
