I'm trying to limit our LDM to ingest CONDUIT data from only the Northeastern
part of the U.S., however I'm not certain what regular expression I should use.
I notice the documentation talks about grid numbers, but I can't seem to find
any documentation on the actual values of these numbers, or what group of
numbers would be considered the Northeast U.S.
I don't have a strong background in meteorology, so perhaps that's my problem,
but surely someone has already done this.
I've noticed that some people use the following REQUEST statements in their
ldmd.conf file:
request CONDUIT "[09]$" host.domain.org
request CONDUIT "[18]$" host.domain.org
request CONDUIT "[27]$" host.domain.org
request CONDUIT "[36]$" host.domain.org
request CONDUIT "[45]$" host.domain.org
I know this divides CONDUIT into 5 separate data channels, but is this limiting
CONDUIT to a certain region? If so, what numbers would I use for the
Northeast? Would it even make sense to limit CONDIUT to a region?
I know that conduit contains several products, and currently we're ingesting
the GFS set with the following entries is our ldmd.conf file:
REQUEST CONDUIT "MT.gfs_CY.*[05]$" ourprimaryhost.domain.org PRIMARY
REQUEST CONDUIT "MT.gfs_CY.*[05]$" idd.cise-nsf.gov ALTERNATE
REQUEST CONDUIT "MT.gfs_CY.*[16]$" ourprimaryhost.domain.org PRIMARY
REQUEST CONDUIT "MT.gfs_CY.*[16]$" idd.cise-nsf.gov ALTERNATE
REQUEST CONDUIT "MT.gfs_CY.*[27]$" ourprimaryhost.domain.org PRIMARY
REQUEST CONDUIT "MT.gfs_CY.*[27]$" idd.cise-nsf.gov ALTERNATE
REQUEST CONDUIT "MT.gfs_CY.*[38]$" ourprimaryhost.domain.org PRIMARY
REQUEST CONDUIT "MT.gfs_CY.*[38]$" idd.cise-nsf.gov ALTERNATE
REQUEST CONDUIT "MT.gfs_CY.*[49]$" ourprimaryhost.domain.org PRIMARY
REQUEST CONDUIT "MT.gfs_CY.*[49]$" idd.cise-nsf.gov ALTERNATE
I believe this reduces our CONDUIT ingestion to a global subset, is that right?
I've also noticed that some people use NGRID with GFS, is this necessary, or
simply a good idea?
I've been bugging the heck out of Unidata Support (Thank you for being patient
with me Tom Yoksas), and trying to glean hints from the support archives, but I
think I'm out of ideas. Any help would be greatly appreciated.
