to the working directory. The file must be copied and edited prior to execution if default settings are to be changed. Preset values and comments on userdef.ncl are meant to aid the user in this respect.

The color maps that are available by editing userdef.ncl are rainbow (default), red-white-blue (recommended for the color blind), shades of gray, tiger stripes and NRL. See example 6 in the documentation of contour.sh for more information. Two of the color maps can have up to 37 different colors, whereas the others are limited to 18 different colors. Note that tiger stripes may well be used with color repetion.

It is also relatively easy to zoom in on a subdomain (see example 2 in the documentation of vector.sh), and to change the vector specification if vectors are present (see example 3 in the documentation of vector.sh). A new feature in v.1.2 is that for depictions on geographical maps, the user may instead zoom in by limiting the range of longitudes & latitudes, see text in 'userdef.ncl' for details.

For the NCL trained user, the present shell scripts may be used to produce a preliminary ncl script for later editing (with the exception of the m*.sh multi-plot scripts), by setting a flag for retaining the ncl script (see the syntax description for each shell script).

The products after execution of the presently provided shell scripts are:
