[Met_help] [rt.rap.ucar.edu #82438] History for Error with MET

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

Hi John,

I am running MET Mode tool on observation and precipitation files. I
noticed this one error for certain 24 hour forecast accumulation,

DEBUG 3: Applying convolution threshold >=10.0 resulted in 242 simple
observation objects.

DEBUG 3: Skipping observation object area threshold.

DEBUG 3: Skipping observation object intensity percentile threshold.

DEBUG 2: Computing contingency table statistics...

DEBUG 2: Identified: 67 forecast objects and 242 observation objects.

DEBUG 2: Performing merging (THRESH) in the forecast field.

DEBUG 2: Performing merging (THRESH) in the observation field.

ERROR  :

ERROR  : FcstObsSet::add_obs(int) -> too many obs numbers!

ERROR  :


Do you know what is causing this? Is there a way to fix it?


Thanks,

Andrew,

I see that you're running MODE to generate a large number of objects.

Looking in src/libcode/vx_shapedata/set.h, I see that we have defined
hard
upper limits:
   static const int max_fcst_numbers = 100;
   static const int max_obs_numbers  = 100;

You could change those to arbitrarily large values... maybe 500 and
then
recompile.

However, I realize that that's less than ideal.  Instead, we should
dynamically allocate as much memory as required rather than having a
fixed
upper limit.  I'll add a development task to update this for MODE in a
future release.

Sorry I don't have a better answer for you.

Thanks,
John Halley Gotway
