Problem with OUTGRID felxpart wrf

Reported by: rab_h Owned by: jbrioude
Priority: major Milestone:
Component: FP other Version: FLEXPART-WRF
Keywords: Cc: rstow



I have a problem to create an outgrid domain.

I need a little bit smaller domain than the mother one.

but i try a lot of values to test and run flexpart-wrf but no thing works.
and already i get this erreur.

£ of vertical levels in WRF data

n_bottom_top & "true" nuvz: 50 50
nwz & "augmented" nuvz: 51 51

nwzmax, nuvzmax, nzmax : 61 61 61
nconvlevmax, nconvlev : 60 49
nx, ny, nxmax, nymax : 149 119 334 334

Mother domain:

east-west range: 0.0 2220000.0 Grid distance: 15000.0
south-north range: 0.0 1770000.0 Grid distance: 15000.0

* ll_to_xyindex_wrf error -- x_i, y_j out of bounds

x_lon, y_lat = 2.160E+08 1.500E+08
x_i, y_j = 1.387E+09 -1.764E+03

forrtl: severe (59): list-directed I/O syntax error,

Now i am confused what i should putting in FORMER OUTGRID namelist.

my domaine is :

LON :-10.52 to 12.52
LAT : 28.22 N 43.07 N

with 15Km resolution and mercator projection

-9.0 OUTLONLEFT geograhical longitude of lower left corner of output grid

29 OUTLATLOWER geographical latitude of lower left corner of output grid
120 NUMXGRID number of grid points in x direction (= # of cells )
100 NUMYGRID number of grid points in y direction (= # of cells )
0 OUTGRIDDEF outgrid defined 0=using grid distance, 1=upperright corner coordinate
1800000 DXOUTLON grid distance in x direction or upper right corner of output grid
1500000 DYOUTLON grid distance in y direction or upper right corner of output grid
3 NUMZGRID number of vertical levels

The way you defined your domain, you asked for a domain with a resolution of 1800000 degrees in longitude and 1500000 degrees in latitude.
Assuming you used the correct option to define your output domain in degrees, you should use for instance:
and say


it will generate your output domain based on the coordinates of your upper right corner (in this case, 12.E and 42.5N)

If you use
then, you need to use the resolution of your output domain in degrees.
