Since March 2022 along with NEMO 4.2 release, the code development moved to a self-hosted GitLab.
This present forge is now archived and remained online for history.

     1Abstract for the simulations performed over 10 years (latest ones are the first presented):[[BR]]

     3   * for [wiki:private/ORCA2Runs/PHC16 PHC_16] based on PHC_15 but :[[BR]] 
     4{{{ 
     5- apply -9% on precipitation & runoff instead of -8% in PHC_15 experiment 
     6}}}

     8   * for [wiki:private/ORCA2Runs/PHC15 PHC_15]: based on PHC_11 but :[[BR]] 
     9{{{ 
     10just use "good" input fields for K1 and M2 waves 
     11}}} 
     12 
     13   * for PHC_12 based on PHC_11 but :[[BR]] 
     14{{{ 
     15few tests to improve transport of few straits: 
     16- fmask = 4.0 at the output of the Baltic sea 
     17- fmask = 0.5 at Gibraltar 
     18- fmask = 1.0 at Bab El Mandeb & add an identical value at one corner of the strait 
     19- one specificity of the Sound strait is an annual mean output flow, so to catch it in outputs, 
     20few modifications have been done in the diafwb.F90 module. further more an error on the location 
     21of the Sound strait has been also corrected 
     22-  
     23}}} 
     24 
     25   * for PHC_11: based on PHC_10 but includes both:[[BR]] 
     26{{{ 
     27it seems that input fields were not the good ones 
     28- global Kz tides  
     29- increased Kz tides in the ITF area 
     30}}} 
     31 
     32   * for [wiki:private/ORCA2Runs/PHC10 PHC_10]: based on PHC_9 but includes both:[[BR]] 
     33{{{ 
     34- 3 waves lenghts penetration (RGB) through the traqsr.F90 module  
     35- ocean color: climatology of a 2D chlorophyll field 
     36}}} 
     37 
     38   * for [wiki:private/ORCA2Runs/PHC9 PHC_9]:  based on the PHC_8 experiment[[BR]] 
     39{{{ 
     40change the way to compute wind stress & wind module: 
     41- wind module is now read and corresponds to ||U||clim, i.e. the one computed using 6hourly components  
     42not the one using climatological components Uclim/Vclim  
     43- wind stress: (||U||.u)clim & (||U||.v)clim fields are directly read instead computed. the drag coefficient is the one  
     44computed using on the wind module read just above. 
     45- in doing this we don't substract anymore relative velocity of the ocean/sea-ice in the computation of the wind module  
     46and the wind stress 
     47}}} 
     48 
     49   * for [wiki:private/ORCA2Runs/PHC4 PHC_4]:  based on the PHC_3 experiment[[BR]] 
     50{{{ 
     51just remove the TKE penetration in setting nn_etau= 0 in namelist:

     53 
     54 
     55   * from PHC_1 to PHC_8 :  
     56{{{ 
     57all these runs have been used for: 
     58- freshwater budget adjustement in playing with new namelist parameters alpha_precip, alpha_runoff 
     59- Gibraltar, Bab El Mandeb & Sound sraits transports adjustement ( based on scale factors or/and bondary condition fmask ) 
     60- they all used the following computation for the wind module:  we add the wind module variance difference  
     61(||U||clim)^2 - (Uclim^2 + Vclim^2) to the computation of the wind module where ||U||clim is the climatological wind module  
     62and Uclim/Vclim are the climatological wind component
