     15''' Motivations'''[[BR]] 
     16Merge of active and passive tracer advection/diffusion modules to avoid duplication of almost identical modules. Continuation of the work done in 2010

    18 '''Status''' 
     18'''Status'''[[BR]] 
    1919The merge has been done for transport routines, using a switch to avoid the suppression of T and S array at this time, See wiki:ticket/664_TRA_TRP

     23'''(1)''' Merge dtatem-dtasal into dtatsd [[BR]] 
     24 
     25In previous version of NEMO, the 3D field of T and S were used for (1) internal damping to levitus (key_tradmp) and (2) for sst and sss restoring. This was the reason why dta_tem and dta_sal where called at the beginning of step before the surface fluxes computation and the tra_dmp call. 
     26 
     27With the new surface module, the optional restoring to sst ans sss now uses another data file containing only the 2D temp and salinity data required for the sea surface restoring. The read of 3D field is now only required if the key_tradmp is defined (and in the initialisation, when starting from levitus). Therefore, the call to dta_tem and _sal can now be moved in tradmp module. Furthermore, it is suggested to combine the two modules (dtatem & dtasal) into a single module as they are almost identical.
