C flt_surf :: "surface" level of the floats. |
| 18 |
C Can be deeper than 1, e.g. IF no mixed layer model is used |
| 19 |

C flt_xLo :: Full domain lower X boundary |

C== Parameters == |
| 36 |
|
| 37 |
C flt_noise :: range of noise added to the velocity component |
| 38 |
C (randomly). The noise can be added or subtracted, |
| 39 |
C the range is +/- flt_noise/2 |
| 40 |
C flt_deltaT :: time-step to step forward floats (in flt_runga2.F) |
| 41 |
C default is deltaTClock |
| 42 |
C flt_int_traj :: period between storing model state at float position, in s |
| 43 |
C flt_int_prof :: period between float vertical profiles, in s |
| 44 |
C |
| 45 |
C note: flt_int_prof is the time between getting profiles, not the |
| 46 |
C the return cycle of the float to the surface. The latter can |
| 47 |
C be specified individually for every float. Because the mechanism |
| 48 |
C for return ing to the surface is called in the profiling routine |
| 49 |
C flt_int_prof has to be the minimum of all iup(max_npart). |
| 50 |
C The subsampling of profiles can be done later in the analysis. |

C flt_file :: name of the file containing the initial positions. |
| 59 |
C At initialization the program first looks for a |
| 60 |
C global file flt_file.data. If that is not found it |
| 61 |
C looks for tiled files flt_file.iG.jG.data. |

C kfloat :: target depth of float. |

C iup :: type of float : |

C o should profile ( > 0 = return cycle, in s, to surface) |
| 92 |
C o remain at depth ( = 0 ) |
| 93 |
C o is a 3D float ( = -1 ) |
| 94 |
C o should be advected without additional noise ( = -2 ). |
| 95 |
C This implies that the float is non-profiling |

C o is a mooring ( = -3 ), i.e. the float is not advected |
