We need names to identify objects and people. In the beginning,
there was variable names (ex. TMP, HGT), the level (ex. surface, 500 mb)
and a date code (ex. 2017010100, x seconds after 1 Jan. 1970).
Then there was a need for forecast time (ex. 12 hour forecast)
and accumulations/averages (0-6 hour accumulation). Life became
more complicated and wgrib2 used the -misc
option to print out the additional items necessary for identification.
The -misc will change with time as
more details are needed to identify the fields. As of 9/2017,
-misc includes ensemble information
(ex 10th member), probability (10% forecast), spatial processing,
wave_partition, JMA specific, climatology, error, confidence indicator,
chemical information and aerosol information.
The -misc option is called by the
-s option and many other similar options.
