20010226: RCM Plotting

Glenn,

The leading pattern:
001 \r \r \n
#### \r \r \n

is actually not part of NOAAPORT- instead, its something that
you are sticking on to make the products look like "FOS". Its
not part of the product.

At any rate, GEMPAK5.6.A should handle stripping off those first
4 lines. Your product actually starts with the:
\0   %   ,   t  \0  \0 332 233
etc.
You could remove the first 4 lines manually like:
tail +5 NCR_20010226_1221 > newfile
You should be able to view newfile using nsat's "user select" browser.
If not, then the product might be encrypted. Its not zlib compressed
since the product portion starts with "\0" and not "x 234". Let me know
if you are able to view it after you strip off the first 4 lines.

I can view the products at:
ftp://weather.noaa.gov/SL.us008001/DF.of/DC.radar/DS.p19r0/
These do have the 2 WMO and PIL but without the leading FOS characters.

>Hello Steve,
>Kudo's to your perseverance on the GRIDDED RCM files- I'm finally
>plotting them.  Now back to my original problem which was the level-III
>rcms'.  I'm getting the data out to directories in the proper structures
>(i.e., NCR/N0R, etc.) but I have all the noaaport junk before the actual
>data.  An od dump reveals:
