[Met_help] [rt.rap.ucar.edu #66187] History for A question about "grid_stat" tool

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

Dear Professor,

I have a question about  'grid_stat' tool.  In the configurable items for Grid-stat, set
output_flag = {
   fho    = NONE;
   ctc    = BOTH;
   cts    = BOTH;
   mctc   = NONE;
   mcts   = NONE;
   cnt    = 
NONE
; sl1l2 = NONE; vl1l2 = NONE; pct = NONE; pstd = NONE; pjc = NONE; prc = NONE; nbrctc = NONE; nbrcts = NONE; nbrcnt = NONE; };
To indicate that contingency table counts (CTC), contingency table statistics (CTS) . Now the question is that if I only want the CSI、GSS ,not all the CTS outputs，how to set it? Look forward to your feedbacks soon.Your help is highly appreciated.Thanks, Crystal

Crystal,

The configuration file for Grid-Stat allows you to turn on/off
different statistic line types, not individual statistics within the
line.  The contingency table statistics line type (CTS) includes CSI
and GSS.  So you should turn the CTS line type on (set to STAT or
BOTH) and turn all the others off (set to NONE).  There is no way to
disable individuals statistics within the CTS line type.

But if you'd like to make grid_stat run faster, make sure that the
number of bootstrap replicates is set to 0:
   boot = {
    ...
    n_rep    = 0;
    ...
   };

Computing bootstrap confidence intervals on gridded data can be quite
slow since there are so many points.  Setting "n_rep = 0" disables the
bootstrapping process, but there's no way of disabling the
computation of the other statistics in the CTS line type.

Hope this helps clarify.  Please let me know if you have other
questions.

Thanks,
John

Dear Professor,
Nice hear from you ! Thank you very much for your help !

Now I have another problem about 'Point_stat' tool , I use the obs
output from "ascii2nc" tool and fcst output from "pcp_combine" tool,
the scripts can be run, but the problem is "Processing APCP_03(*,*)
versus APCP/A03, for observation type ADPSFC, over region FULL, for
interpolation method UW_MEAN(9), using 0 pairs." It is very strange
there is no pairs matched. I am wandering why.
I have posted the data I am using to the ftp site.The folder is
/met_help/qiu. Please help me.
Very thanks!
Crystal
