    681681numeric of the code, so that the trajectories never intercept the bathymetry.  
    682682 
    683 Input coordinates can be with Ariane Tools convention ( IJK coordinates ,(\np{ln\_ariane}=true) ) 
     683\subsubsection{ Input data: initial coordinates } 
     684 
     685Initial coordinates can be given with Ariane Tools convention ( IJK coordinates ,(\np{ln\_ariane}=true) ) 
    684686or with longitude and latitude. 
     687 
     688 
     689In case of Ariane convention, input filename is \np{"init\_float\_ariane"}. Its format is: 
     690 
     691\texttt{ I J K nisobfl itrash itrash } 
     692 
     693\noindent with:  
     694 
     695 - I,J,K  : indexes of initial position 
     696 
     697 - nisobfl: 0 for an isobar float, 1 for a float following the w velocity   
     698 
     699 - itrash : set to zero; it is a dummy variable to respect Ariane Tools convention 
     700 
     701 - itrash :set to zero; it is a dummy variable to respect Ariane Tools convention 
     702 
     703\noindent Example: 
     704 
     705\noindent \texttt{ 100.00000  90.00000  -1.50000 1.00000   0.00000}\\ 
     706\texttt{ 102.00000  90.00000  -1.50000 1.00000   0.00000}\\ 
     707\texttt{ 104.00000  90.00000  -1.50000 1.00000   0.00000}\\ 
     708\texttt{ 106.00000  90.00000  -1.50000 1.00000   0.00000}\\ 
     709\texttt{ 108.00000  90.00000  -1.50000 1.00000   0.00000}\\ 
     710 
     711 
     712In the other case ( longitude and latitude ), on, input filename is \np{"init\_float"}. Its format is: 
     713 
     714\texttt{ Long Lat depth nisobfl ngrpfl itrash} 
     715 
     716\noindent with: 
     717 
     718 - Long, Lat, depth  : Longitude, latitude, depth 
     719 
     720 - nisobfl: 0 for an isobar float, 1 for a float following the w velocity 
     721 
     722 - ngrpfl : number to identify searcher group 
     723 
     724 - itrash :set to 1; it is a dummy variable. 
     725 
     726\noindent Example: 
     727 
     728\noindent\texttt{  20.0 0.0 0.0 0 1 1 }\\ 
     729\texttt{ -21.0 0.0 0.0 0 1 1 }\\ 
     730\texttt{ -22.0 0.0 0.0 0 1 1 }\\ 
     731\texttt{ -23.0 0.0 0.0 0 1 1 }\\ 
     732\texttt{ -24.0 0.0 0.0 0 1 1 }\\ 
     733 
     734 
     735\subsubsection{ Output data } 
    685736 
    686737\np{jpnfl} is the total number of floats during the run. 
     
    691742is the frequency of creation of the float restart file. 
    692743 
    693 Output data can be written in ascii files (\np{ln\_flo\_ascii = .TRUE.} ) or in Netcdf files. In the case 
    694 of netcdf outputs, fields are selected in iodef.xml file when IOM is used (\key{iomput}).  
     744Output data can be written in ascii files (\np{ln\_flo\_ascii = .TRUE.} ). In that case,  
     745output filane is \np{is trajec\_float}  
     746 
     747Another of writing format is Netcdf. There are 2 possibilities: 
     748 
     749 - if (\key{iomput}) is used, outputs are selected in  \np{iodef.xml}. Here it is an example of specification  
     750   to put in files description section: 
     751 
     752\vspace{-30pt} 
     753\begin{alltt}  {{\scriptsize 
     754\begin{verbatim} 
     755 
     756     <group id="1d\_grid\_T" name="auto" description="ocean T grid variables" >   } 
     757       <file id="floats"  description="floats variables"> }\\ 
     758           <field ref="traj\_lon"   name="floats\_longitude"   freq\_op="86400" />} 
     759           <field ref="traj\_lat"   name="floats\_latitude"    freq\_op="86400" />} 
     760           <field ref="traj\_dep"   name="floats\_depth"       freq\_op="86400" />} 
     761           <field ref="traj\_temp"  name="floats\_temperature" freq\_op="86400" />} 
     762           <field ref="traj\_salt"  name="floats\_salinity"    freq\_op="86400" />} 
     763           <field ref="traj\_dens"  name="floats\_density"     freq\_op="86400" />} 
     764           <field ref="traj\_group" name="floats\_group"       freq\_op="86400" />} 
     765       </file>}\\ 
     766  </group>} } 
     767 
     768\end{verbatim} 
     769}}\end{alltt} 
     770 
     771 
     772 -  if (\key{iomput}) is not used, a file called \np{trajec\_float.nc} will be created by IOIPSL library.
