[CONDUIT #OMX-565412]: LDM CONDUIT config

> Hello,

Hi Dan, 

It looks like this slipped through the cracks :(

OK

Who are you "feeding" from?


 The name on record for those feeds is likely David Welsh.

Sure :)

Have you seen:
http://www.unidata.ucar.edu/data/conduit/ldm_idd/index.html

This should help you form a regular expression for the data you desire, we can 
help if needed.

Yes, two pqact entries will be needed:

1) a FILE command to keep native

2) a PIPE to a decoder for grib to netcdf transform

Apologies for the delay, was not overly verbose in case this was resolved and 
just not closed, we are here for any
additional support, and we/I will assure you it will not languish!
