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.
