    Hi Lin,

    You might want to consider using NCL (NCAR Command Language) for your
    application, since we have developed some NCL scripts that do
    nice-looking polar stereographic plots with latitude/longitude labels.
    NCL is built on top of NCAR Graphics, so you still get the high
    quality graphics. NCL is especially useful if you have netCDF, HDF,
    or GRIB data, as there is a simple interface in NCL for reading these
    files.

    To see some of the polar stereographic plots that can be created and
    the NCL scripts that created them, go to:

      http://www.cgd.ucar.edu/csm/support/CSM_Graphics/polar.shtml

    This web site was developed by Sylvia Murphy in the Climate and Global
    Dynamics Division at NCAR. They use NCL heavily for both model and
    observational data, and Sylvia has set up this web site to provide
    lots of NCL examples for doing various kinds of plots, especially for
    use with the CCSM (Community Climate System Model)

    If you decide to go this route, let me know via a personal email
    message, and I'll help you with masking the values over the ocean.

    There are some masking examples at:
