[LDM #MBO-227000]: NBM product

Hi,

re:

> Can some one provide us some help regarding this request?

The first thing to do when checking to see if a desired (set of) product(s)
is available in the IDD is to determine what the products WMO IDs look
like.

A quick Google (tm) search using the terms:

 national blended model guidance products wmo id

returns in its list:

WMO Headings for National Blend of Models Text Products
https://www.weather.gov/media/mdl/nbm/NBM%20V3.2%20Text%20Product%20WMO%20Header%20Scheme.pdf

This PDF:

​​WMO Headings for National Blend of Models Text Products
Effective with implementation of NBM V3.2 – November 2019

describes the WMO header for these products:

WMO headings have the format of T1T2A1A2ii CCCC1.

1. The originating center ID (CCCC) for National Blend of Models text products 
is KWNO
   indicating that they originate from the Meteorological Development 
Laboratory.

2.The T1 represents the data type:
  F = Forecasts

3.The T2 represents the product type:
  O = Guidance (short-range)
  E = Guidance (extended-range)

4.A1A2 represents the geographical area:
  US = United States

5.ii further designates bulletin type as follows:

  For T2=O
  15 = Hourly (1-24 hours)
  16 = Short-range (6-66 hours)

  For T2=E1
  16 = Extended (12-192 hours)
  17 = Extra-extended (204-264 hours)
  18 = Probabilistic (out to 10 days)

and so on.

Based on this one can use the LDM utility 'notifyme' to see if products
that have WMO IDs that match this formalism are available in the IDD:

<as 'ldm'>
notifyme -vl- -f ANY -h idd.unidata.ucar.edu -p "F[OE]US1[5678] KWNO" -o 3600

This invocation should produce a listing that looks like:

and so on.

This listing shows that the products that have WMO IDs that match the pattern
(-p flag value) are in the NGRID feed (which originates from the NOAAPort SBN).

If these are, in fact, the desired products, than the following LDM 
configuration
file REQUEST line would request them:

REQUEST NGRID "F[OE]US1[5678] KWNO" <upsteam feed host>

where one would replace 'upstream feed host' with the fully qualified
name or IP address of the upstream LDM host that relays the NGRID feed.

Cheers,

Tom
