            SI.cccc/    Data site: A radar site for each data subcategory for all 200 sites.

Delivery Details.

Data files are updated on the FTP server every five minutes or sooner with data from the RPG or SPG.
 
File names within each radar site directory have the format sn.nnnn where nnnn is a four-digit number ranging from 0000 to 0250.

Files are written in sequence with the file sn.0000 following sn.0250.
 
This scheme provides unique file names for at least the previous 48 hours of data received, as older files are over-written.


A sample of the most recently written radar file (base reflectivity - 54 nmi range, elevation of 1.5°) for Dallas/Fort Worth, TX is:
SL.us008001/DF.of/DC.radar/DS.p19r1/SI.kfws/sn.0114.

Data files are written only when data of that subcategory type is available.
