DESCRIPTION

ncpdq packs or re-shapes variables in input-file and stores them in output-file. Which
variables to pack/unpack are determined by the packing policy encoded in the pck_plc
argument to the -P switch. Valid pck_plc options are all_new, all_xst, xst_new, and upk.
The numeric type of variable to pack or re-pack a variable to is determined by the packing
map encoded in the pck_map argument to the -M switch. Valid pck_map options are flt_byt,
flt_sht, hgh_byt, hgh_sht, and nxt_lsr.

ncpdq re-shapes variables in input-file by re-ordering and/or reversing dimensions
specified in the dimension list. The dimension list is a comma separated list of
dimension names, optionally prefixed by negative signs, that follow the -a switch. To re-
order variables by a subset of their dimensions, specify these dimensions in a comma-
separated list following -a, e.g., -a lon,lat. To reverse a dimension, prefix its name
with a negative sign in the dimension list, e.g., -a -lat. Re-ordering and reversal may
be performed simultaneously, e.g., -a lon,-lat,time,-lev.

Users may specify any permutation of dimensions, including permutations which change the
record dimension identity. The record dimension is re-ordered like any other dimension.
The record dimension is always the most slowly varying dimension in a record variable.
The specified re-ordering will fail if it requires creating more than one record dimension
amongst all the output variables.
