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().

...

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.

Data

Defines how Specifies the location of the input data files and the AVAILABLE file is specified. If it is set to Icon the input is specified via using a FLEXPART Prepare icon in parameter Input Data. While if it is set to Path then parameters Input Path and Available File Path specifie he input data. The default value is Icon. Input Data

Holds a FLEXPART Prepare icon specifying the input data location. Enabled when Input Mode is set to Icon.

. Please note that if an icon is  set here it takes preference over the path specified in Input Path.

Input Input Path

Specifies the location of the input data (GRIB) files files and the AVAILABLE file. Both an absolute and relative path can be given here. Enabled when Input Mode is set to Path. 

Available File Path

Specifies the location of the AVAILABLE file. If the default value (the string literal SAME_AS_INPUT_PATH) is set or left blank it indicates that the AVAILABLE file is located in the same directory as the input data. Enabled when Input Mode is set to Path.  

...

Please note that when an icon is specified in Input Data the path specified here is ignored.

User Exe Path

Specifies a user defined FLEXPART executable. Both absolute and relative path can be given here. If it is left blank (this is the default) Metview will use the MV_FLEXPART_EXE environment variable to locate the executable.

User Resources Path

Specifies the location of the

user defined parameter files (IGBP_int1.dat, OH_7lev_agl.dat, surfdata.t, surfdepo.t ) needed to run FLEXPART. Both an absolute and relative path can be given here.

...

If it is left blank (this is the default) Metview will use the MV_FLEXPART_RESOURCES environment variable to locate the resources

Simulation Direction

Specifies the FLEXPART simulation direction in time. The possible values are: Forward and Backward. The default value is Forward.

...

Specifies the beginning date of the simulation in YYYYMMDD format.   Relative dates are allowed: e.g. -1 means yesterday, 0 means today, etc.   

...

Specifies the frequency for the output generation. The output is averaged over the period given in Output Averaging Interval. The format is HHHHHHH[:MM[:SS]]. The default value is 3 (hours).

...

Specifies the averaging interval for the output generation in HHHHHHH[:MM[:SS]] format.  If 0 is given here instantaneous values are written into the output files. The default value is 3 (hours).

...

Specifies the sampling rate used for the averaging of the output. This period must be shorter than the Output Averaging Interval. The format is HHHHHHH[:MM[:SS]]. The default value is 1 (hour).

...

Specifies the type of the gridded output. The possible values are: none (no gridded output), conc (concentration), mixr (mass mixing ratio) and both (concentration and mass mixing ratio). The default value is conc. 

...

Specifies the list of height levels of the gridded output. The levels are given in metres units. The default value is an empty list.

User Species Path

Specifies the location of the user defined species files files. Both an absolute and relative path can be given here. If the default value (the string AS_MV_FLEXPART_SPECIES) is used or left blank Metview will use the MV_FLEXPART_SPECIES environment variable to locate the species.
