I've attached a filter for the LDM to decompress the NIDS data directly by the LDM. Compile it with: cc ucnids.c -o ucnids -lz /******************************************************************** * ucnids - NIDS decompression utility for data compressed with zlib * * syntax: ucnids [options] ifile ofile * ifile and ofile can be "-" to use standard input and output * options: * none - output uncompressed product with NOAAPORT CCB * -c - output with standard WMO CCB * -w - output with WXP-like WMO header * -n - output stripping header and leaving raw NIDS data ********************************************************************/ Here is how I use it in the LDM: # # Radar - NIDS WMO ^SDUS5. .... ([0-3][0-9])([0-2][0-9])([0-5][0-9]).*/p(...)(...) PIPE -close /home/ldm/bin/ucnids -c - /home/ldm/data/nids/\5/(\1:yy)( \1:mm)\1\2\3_\4.nid BTW, WXP can handle all 4 of the above outputs plus the original compressed format. ________________________________________________________ Daniel Vietor Mail: devo@xxxxxxxxxxxxx Unisys Corp Title: Engineer/Meteorologist 221 Gale Lane Phone: 610-925-5206 Kennett Square PA 19348 Fax: 610-925-5215
