Calculation of hfds

Dear all,

When calculating hfds for the CMIP output, we use the following formula in cmorise package:

hfds = sum(sfc_hflux_from_runoff, sfc_hflux_coupler, sfc_hflux_from_water_evap, sfc_hflux_from_water_prec, frazil_2d)

Did you use the same formula or something different? I couldn’t find frazil_2d outputs in the JRA55 or ERA5 IAF one-degree ocean outputs, and neither from_runoff nor from_water_xxx are included. Does this mean we calculate hfds differently in the /g/data/ik11/outputs/access-om2/1deg_era5_iaf/ outputs?

Cheers,

Arnold
