r2906 r2916 681 681 numeric of the code, so that the trajectories never intercept the bathymetry. 682 682 683 Input coordinates can be with Ariane Tools convention ( IJK coordinates ,(\np{ln\_ariane}=true) ) 683 \subsubsection{ Input data: initial coordinates } 684 685 Initial coordinates can be given with Ariane Tools convention ( IJK coordinates ,(\np{ln\_ariane}=true) ) 684 686 or with longitude and latitude. 687 688 689 In 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}\\ 710 711 712 In 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 } 685 736 686 737 \np{jpnfl} is the total number of floats during the run. … … 691 742 is the frequency of creation of the float restart file. 692 743 693 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}). 744 Output data can be written in ascii files (\np{ln\_flo\_ascii = .TRUE.} ). In that case, 745 output filane is \np{is trajec\_float} 746 747 Another 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. 773 774 695 775 696 776 See also \href{http://stockage.univ-brest.fr/~grima/Ariane/}{here} the web site describing
