Neil,

Here is an example of the FILE action we use for all NEXRAD Level III
products in the IDD:

# NEXRAD feedtype,
NEXRAD  ^SDUS5. .... ([0-3][0-9])([0-2][0-9])([0-6][0-9]).*/p(...)(...)
        FILE    -close  
data/pub/raw/nexrad/nids_(\1:yyyy)(\1:mm)\1/\5/\4/\4_(\1:yyyy)(\1:mm)\1_\2\3

The things to note in this action are:

o keying on the '/p' portion of the header
o using the two fields in the '/p' action to get the NEXRAD station ID
  and product type

The first three character group in '/p' is the product name (e.g., N0R,
NVL, NTP, etc.); the second character group in '/p' is the three
character station ID (e.g., FTG, GLD, BIS, etc.).

The correspondence between the WSI and NOAAPORT product naming schemes
is:
