[Wrf-users] wrfout_d01 discrepancy on XLONG between 1st and 2nd file

[HEDDE Thierry]

Hi to the WRF community,

WRF3.1.1, 3 nested domains

I found a discrepancy on values of XLAT or XLONG variables between the first mother grid wrfout_d01 file and the following ones. (FLEXPART_WRF feels bad about it!).
There is no problem with inner domains.

Please check whether you have the same problem, by typing similar UNIX commands with your own wrfout_d01 files:

    ncdump -f f -v XLONG wrfout_d01_2009-07-08_12:00:00 > X1.out
    ncdump -f f -v XLONG wrfout_d01_2009-07-08_13:00:04 > X2.out
    diff X1.out X2.out | more

where one of the wrfout file must be the first one.

Here is the result of my diff command:
    <     5.918274,  // XLONG(56,53,1)
    >     5.918243,  // XLONG(56,53,1)

which is a about a 3 meter error.

Thanks
