[Met_help] [rt.rap.ucar.edu #101298] History for How to turn off smoothing

  Initial Request
----------------------------------------------------------------

Hello, John 
I am a beginner of MET，I want to use grid-stat to obtain CSI, but I found that I got two different CS，which may be caused by the use of different interpolation methods.（INTERP_PNTS 9 or 25） . I found there are "Both", "OBS" and "FCST" options in the user guide. How can I turn off smoothing? I tried "NONE", but it doesn't seem to work.
Thank you very much.

“interp
The “interp” entry is a dictionary that specifies what interpolation or smoothing (for the Grid-Stat tool) methods should be applied. This dictionary may include the following entries:
The “field” entry specifies to which field(s) the interpolation method should be applied. This does not apply when doing point verification with the Point-Stat or Ensemble-Stat tools:
“FCST” to interpolate/smooth the forecast field.
“OBS” to interpolate/smooth the observation field.
“BOTH” to interpolate/smooth both the forecast and the observation.”
Here is my config：
“}

////////////////////////////////////////////////////////////////////////////////

//
// Data smoothing methods
//
interp = {
   field      = NONE;
   vld_thresh = 1.0;
   shape      = SQUARE;

   type = [
      {
         method = NEAREST;
         width  = 1;
      }
   ];
}”
