Q. What are the possible values for "center" and "subcenter"?
A. The center refers to who generated it, and can be found on http://www.wmo.int/pages/prog/www/WMOCodes/WMO306_vI2/LatestVERSION/LatestVERSION.html by clicking on "Common Code Tables to Binary and Alphanumeric Codes"(pdf) The subcenter is allocated by the originating Center. In GRIB2 they can have a value between 0 and 65535, where 65535 indicates missing.
Q. Why does "tar" keeps producing a "checksum error"?
A. On the Sun platform, the "tar" executable (located under /usr/bin) is not 100% compatible with "GNU tar". Sun users are recommended to look for "/usr/local/bin/gtar".
