definition of fr1_i0 and fr2_i0 in coupled mode?

[smasson]

1) in coupled mode, fr1_i0 and fr2_i0 are defined as constant values:

      fr1_i0(:,:) = 0.18
      fr2_i0(:,:) = 0.82

2) In sbcblk_core they are defined as

      p_fr1(:,:) = ( 0.18 * ( 1.0 - zcoef_frca ) + 0.35 * zcoef_frca )
      p_fr2(:,:) = ( 0.82 * ( 1.0 - zcoef_frca ) + 0.65 * zcoef_frca )

but as zcoef_frca is defined as a constant equal to

      zcoef_frca   = 1.0  - 0.3

this means that fr1_i0 and fr2_i0 are in fact defined as constant values...

      fr1_i0(:,:) = 0.299
      fr2_i0(:,:) = 0.701

3) In sbcblk_clio they are defined as

            p_fr1(ji,jj) = 0.18  * ( 1.e0 - sf(jp_ccov)%fnow(ji,jj,1) ) + 0.35 * sf(jp_ccov)%fnow(ji,jj,1) 
            p_fr2(ji,jj) = 0.82  * ( 1.e0 - sf(jp_ccov)%fnow(ji,jj,1) ) + 0.65 * sf(jp_ccov)%fnow(ji,jj,1)

which means that they really depend on the could cover that is prescribed in the forcing fields.

What should be do in coupled mode?

• keep the values as it is?
• use the values used in sbcblk_core?
• give the possibility to receive the cloud cover from the atmosphere?
