[Met_help] [rt.rap.ucar.edu #76781] History for auto AVN replacement to GFS in tc_pairs and tc_stat

[John Halley Gotway via RT]

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

Hi John,

I've run into an issue with tc_pairs when trying to use a model name that
contains "AVN". We test various consensus products that are often named
according to the input models being excluded or included. Could the logic
of tc_pairs / tc_stat be changed such that "AVN" isn't automatically
replaced with "GFS"? We can definitely work around this issue by choosing
different names, but it would be great to be able to use "AVN".

Thanks,
Andy

Hi Andy,

It's funny that you mention that.  I've always felt like that
conversion is
a bit contrived.  But we were instructed to replicate the
functionality of
NHC and that's what their logic mandates.

Ideally, we'd be able to keep that conversion of AVN to GFS as the
default
behavior, but provide a way (likely through the config file) to
override it.

I can tell you that renaming is done in a single line of code... line
261
of the file atcf_line.cc:

    253 ConcatString ATCFLine::technique() const {
    254    ConcatString cs;
    255
    256    // Use Technique, if already set
    257    if(Technique) cs = Technique;
    258    else          cs = get_item(TechniqueOffset);
    259
    260    // Replace instances of AVN with GFS
    261    cs.replace("AVN", "GFS");
    262
    263    return(cs);
    264 }

Commenting out that line and recompiling would provide a quick and
dirty
way to disable it for now.

I'll ask around about a better long term solution.

John

Hi John,

Thanks for the workaround. One difference between the logic of
tc_pairs and
NHC's verification is that either "AVNI" or "GFSI" can be requested
and
verified (it knows to search for AVNI), it will just be output as
"GFSI".
Very confusing (and unnecessary in my opinion)!

Thanks and take care,
Andy
