This icon runs the FLEXPART Lagrangian particle dispersion model and converts its outputs to formats Metview can work with. For help on editing icons, please see Editing Icons.

The macro language equivalent is flexpart_run().

The FLEXPART Run Editor

Info
All the date parameters used for FLEXPART Run have yyyymmdd format. Relative dates are allowed: e.g. -1 means yesterday, 0 means today, etc.                   

Output Path

Specifies the location of the output data files. Both an absolute and relative path can be given here.

...

Specifies the location of the input data files and the AVAILABLE file using a FLEXPART Prepare icon. Please note that if an icon is  is set here it takes preference precedence over the path specified in Input Path.

...

Specifies the list of times for the age class calculation. If it is left blank (this is the default value) no age class is defined.  

Particle Splitting

...

Specifies the time constant interval for particle splitting in HHHH[:MM[:SS]] format. Particles are Each particle is split into two after every N seconds given here. If -1 travelling the multiple of this interval. If 0 (default value) is given here particle splitting is not used. The default value is -1 (no splitting)disabled.

Sync Interval

All processes are synchronized with this time interval, therefore, all other time constants must be multiples of this value. Output interval and Output Averaging Interval must  must be at least twice of this value. The default value is 900.

  • none
  • full: in this mode the the particles are not released at specific locations but the 3D-volume of the first release is taken and the particles are uniformly distributed in the volume proportionally to air density.Each particle will receive the same mass, altogether accounting for the total atmospheric mass. Subsequently, particles can move freely in the atmosphere.
  • o3_tracer: in this mode domain-filling is to simulate a stratospheric ozone tracer. This option is similar to fill option, but only particles in the stratosphere (defined by PV < 2 pvu) are released.
