NEXRAD national composites are available on the FNEXRAD IDD data feed as PNG-compressed GINI images. The typical LDM pattern action to receive and file all composites is:
FNEXRAD ^rad/NEXRCOMP/(...)/(...)_(........)_(....)

Level II data are available as raw bz2 files. The filing of data is a two step process, with the raw data first written to a hidden temporary file before being renamed when the last part of the data file is received.

Level 3 products are available on the NEXRAD3 data feed. For all products at all WSR-88D locations nationwide, use the following pattern action:
NEXRAD ^SDUS[23578]. .... ([0-3][0-9])([0-2][0-9])([0-6][0-9]).*/p(...)(...) FILE -overwrite -close data/gempak/nexrad/NIDS/\5/\4/\4_(\1:yyyy)(\1:mm)\1_\2\3
To get all tilt 0 for all sites:
NEXRAD ^SDUS[23578]. .... ([0-3][0-9])([0-2][0-9])([0-6][0-9]).*/p(N0.)(...) FILE -close data/gempak/nexrad/NIDS/\5/\4/\4_(\1:yyyy)(\1:mm)\1_\2\3
For a single product (N1P):
