[LDM #FVG-157850]: ldmd.conf & pqact.conf



Hi Elmer,

Are you doing this with your own NOAAPORT reception system, or are
you doing this by requesting the data from an IDD node?  Just curious...

Yes, this is an easy thing to do using the LDM.

The general pqact.conf pattern we use for processing NEXRAD Level III data is:

#########################################################################
#
# NNEXRAD section
#
#########################################################################

#
####              NEXRAD Level III radar products
#

# FILE everything
NNEXRAD ^SDUS[2357]. .... ([0-3][0-9])([0-2][0-9])([0-6][0-9]).*/p(...)(...)
        FILE    -close  data/nexrad/NIDS/\5/\4/\4_(\1:yyyy)(\1:mm)\1_\2\3

This will create a hierarchical directory structure that looks like:

<as 'ldm'>
cd ~ldm

ls data/nexrad/NIDS

If you want only the base reflectivity products filed, then you can change
the pqact.conf pattern to look like:

# FILE base reflectivities for all stations (N0R)
NNEXRAD ^SDUS[2357]. .... ([0-3][0-9])([0-2][0-9])([0-6][0-9]).*/p(...)(N0R)
        FILE    -close  data/nexrad/NIDS/\5/\4/\4_(\1:yyyy)(\1:mm)\1_\2\3

NOTEs:

- pqact.conf patterns require tabs as whitespace in several places.  If you
  use spaces instead of tabs in those locations, your pattern will not work.
  The pattern listed immediately above is read:

NNEXRAD<tab>^SDUS[2357]. .... ([0-3][0-9])([0-2][0-9])([0-6][0-9]).*/p(...)(N0R)
<tab>FILE<tab>-close<tab>data/nexrad/NIDS/\5/\4/\4_(\1:yyyy)(\1:mm)\1_\2\3

- again, if you only want to FILE the N0R products, you might want to eliminate
  the product type part of the hierarchical storage.  One way to do this would
  be to use the following pattern:

# FILE base reflectivities for all stations (N0R)
NNEXRAD ^SDUS[2357]. .... ([0-3][0-9])([0-2][0-9])([0-6][0-9]).*/p(...)(N0R)
        FILE    -close  data/nexrad/NIDS/\5/\4_(\1:yyyy)(\1:mm)\1_\2\3

- it is your responsibility to control the number of data products you keep
  on disk; the LDM does NOT do the data scouring for you.  If you want to keep
  days of NEXRAD Level III data, you can use the LDM's scour utility to do
  the data scouring.  Please refer to the LDM HomePage for additional details.


So, you see that it is very easy to save the data in the way that you want.

Cheers,

Tom
