Re: 20040609: DVB readnoaaport software

Hi Tom,

I'll take a look at sigco.pgm, thanks.  Outputting data to non-standard file names shouldn't be too hard assuming that the internal structure is unchanged.  As to the grid filing, Scott Lindstrom is mostly finished with a GRIB server that will eliminate the XCD grid decoder.  Instead XCD will just file the GRIB messages using a modified version of the existing GRIB filer.  This will get rid of RTMODELS.CFG and make the process (on the XCD side) much simpler.  I believe he is (or will be) looking into modifying the GRIB server to support GRIB2 as well.

Thanks,
Todd

Hi Todd,

  

We have ordered the DVB receivers and expect them in a week or so.
    

I will assume that you are buying the NOVRA S75 units?

  

I'll 
contact you when we're close to being ready to set up a system for testing.
    

OK.

  

XCD heads up:  We found that the XCD grid decoder does not include a 
change that you made a year or two ago to fix some NCEP Vs. ECMWF grid 
confusion.  We had to back out of it then because it broke our ECMWF 
grid ingest.  The problem only crops up on high res grids coming in from 
the CONDUIT feed so we didn't notice it during our testing.  We're 
testing your fix (Mcmkmcgrid.f) and will be releasing an addendum very soon.
    

Here is another heads up for XCD:  sigco.pgm does an include of
m0xcd.inc before it does an 'implicit none'.  Since m0xcd.inc declares
types of variables, it will cause a compilation error on some platforms
when built with gcc/g77.  The solution is simple: move the include to
after the 'implicit none'.

On a related topic...  What is _really_ needed in XCD is:

- being able to name output files in a non-standard manner.  Here are
  two examples:

  20040611_sfc.md     - instead of MDXX0003
  20040611_gfs_12.gid - instead of GRIDnnnn

  This is doable now that DSSERVE can create MD and GRID datasets using
  DIRFILE=.  The beauty of this is that it would get rid of the
  incredibly hard to understand RTMODELS.CFG file.

- the ability of XCD to decode GRIB2 model data (this is a biggie!)

- data compression in decoded GRID files

Anybody thinking about things like this?  :-)

Cheers,

Tom
