XLAT discrepancy in wrfout_d01 files for same(i,j)

[hedde]

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 problem, by typing similar UNIX commands with your own wrfout_d01 files:

Code: Select all

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:

Code: Select all

<     5.918274,  // XLONG(56,53,1)
>     5.918243,  // XLONG(56,53,1)


which is a about a 3 meter error.
Thanks

The problem seems to have disappeared with the WRF V3.2.1. Tested on one result files (but it was only a one domain run).
