    45    * for [wiki:private/ORCA2Runs/PHC16 PHC_16] based on PHC_15 but :[[BR]] 
    46 {{{ 
    47 - apply -9% on precipitation & runoff instead of -8% in PHC_15 experiment

    51 {{{ 
    52 just use "good" input fields for K1 and M2 waves 
    53 }}} 
    54  
    55    * for PHC_12 based on PHC_11 but :[[BR]] 
    56 {{{ 
    57 few tests to improve transport of few straits: 
    58 - fmask = 4.0 at the output of the Baltic sea 
    59 - fmask = 0.5 at Gibraltar 
    60 - fmask = 1.0 at Bab El Mandeb & add an identical value at one corner of the strait 
    61 - one specificity of the Sound strait is an annual mean output flow, so to catch it in outputs, 
    62 few modifications have been done in the diafwb.F90 module. further more an error on the location 
    63 of the Sound strait has been also corrected

    70 - global Kz tides  
    71 - increased Kz tides in the ITF area

    73  
    74    * for [wiki:private/ORCA2Runs/PHC10 PHC_10]: based on PHC_9 but includes both:[[BR]] 
    75 {{{ 
    76 - 3 waves lenghts penetration (RGB) through the traqsr.F90 module  
    77 - ocean color: climatology of a 2D chlorophyll field 
    78 }}} 
    79  
    80    * for [wiki:private/ORCA2Runs/PHC9 PHC_9]:  based on the PHC_8 experiment[[BR]] 
    81 {{{ 
    82 change the way to compute wind stress & wind module: 
    83 - wind module is now read and corresponds to ||U||clim, i.e. the one computed using 6hourly components  
    84 not the one using climatological components Uclim/Vclim  
    85 - wind stress: (||U||.u)clim & (||U||.v)clim fields are directly read instead computed. the drag coefficient is the one  
    86 computed using on the wind module read just above. 
    87 - in doing this we don't substract anymore relative velocity of the ocean/sea-ice in the computation of the wind module  
    88 and the wind stress 
    89 }}}

    91    * for [wiki:private/ORCA2Runs/PHC4 PHC_4]:  based on the PHC_3 experiment[[BR]]

    99 all these runs have been used for: 
    100 - freshwater budget adjustement in playing with new namelist parameters alpha_precip, alpha_runoff 
    101 - Gibraltar, Bab El Mandeb & Sound sraits transports adjustement ( based on scale factors or/and bondary condition fmask ) 
    102 - they all used the following computation for the wind module:  we add the wind module variance difference  
    103 (||U||clim)^2 - (Uclim^2 + Vclim^2) to the computation of the wind module where ||U||clim is the climatological wind module  
    104 and Uclim/Vclim are the climatological wind component
