[MITgcm-support] A query about EXF

[Abhisek Chakraborty]

Dear Dimitris Menemenlis,

I am using 63m version of the model and and the EXF_OPTIONS.h (e.g.
"global_with_exf") shows a table like the following one:

c    WIND |TEMP |DOWN |BULK |EVAP |            actions
c    -----|-----|-----|-----|-----|-------------------------------------
c         |     |     |     |     |

c         |     |     |     |     | swflux, and sflux.
c         |     |     |     |     |

Here I didn't find how to use hs and hl as inputs to EXF.

 (As far as I understand, EXF is using the above parameters to compute
mainly wind stresses and sensible as well as latent heat fluxes. SO THERE
MUST BE SOME MEANS TO USE UWIND, VWIND, HS AND HL DIRECTLY IN THE EXF
PACKAGE).

Any suggestion .....

regards,
Abhisek
