[Wrf-users] Error in DX and DY when running WRF after WPS

[Don Morton]

Just a thought - are any of your dx/dy values in your namelist.input
fractional (e.g. 3333.33)?  I've found that you need to specify these
exactly as they're listed in your wrfinput files.  So, use ncdump to
view your DX/DY values in the wrfinput file, then make sure you list
them in your namelist.input the same way.

As far as WRF (or just about any programming language, for that
matter) is concerned, 1.66667 is not the same as 1.67.

If you're not using fractional dx/dy values, then it still wouldn't hurt
to use ncdump on your wrfinput files to double-check that you
have your namelist.input value specified the same way.
