Teresa,
The resolution depends on where the file are obtained from, conduit feed
give the 1x1 resolution and the NOAAPORT is the 1.25x1.25 resolution. I
included the avn-1x1.cdl file that I created. The patterns are much
different, something like: *fh.0000_tl.press_gr* You can use the notifyme
command to find the names of the products, ie
%notifyme -vl - -f CONDUIT

fh.0192_t1.press_gr.2p5deg (where fh = 0192 - 0384)
61 one degree files per cycle -- 61*700kb=42.7Mb
17 2.5 degree files per cycle -- 17*200kb=3.4Mb
Total -- 46.1 Mb increase per cycle
4 cycles per day -- 184.4 Mb
