New URL for NEMO forge!   http://forge.nemo-ocean.eu

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.

    3030Direct initialization (DI) refers to the instantaneous correction 
    3131of the model background state using the analysis increment. 
    32 DI is used when \np{ln_asmdin} is set to true.

    4141IAU is a common technique used with 3D assimilation methods such as 3D-Var or OI. 
    42 IAU is used when \np{ln_asmiau} is set to true.

    118118$A_D = \alpha e_{1t} e_{2t}$, where $\alpha = 0.2$. The divergence damping is activated by 
    119 assigning to \np{nn_divdmp} in the \textit{nam\_asminc} namelist a value greater than zero.  
     119assigning to \np{nn\_divdmp} in the \textit{nam\_asminc} namelist a value greater than zero.  
    120120By choosing this value to be of the order of 100 the increments in the vertical velocity will  
    121121be significantly reduced.
