_Wrap Functions

Most NCL built-in functions do not transfer, maintain, or create metadata. Specialized wrapper functions have been created to duplicate the behavior of a built-in function while preserving meta data. Metadata is often used in:

the creation of netCDf or HDF files
graphics via the gsn_* high-level graphical interfaces

All _Wrap functions take the identical arguments of the corresponding built-in function and reside in the contributed.ncl library. This llibary must be loaded prior to use:

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"
