POST-PROCESSING wkColorMap, as set in your .hluresfile can be overwritten in any NCL script with the use of the function “gsn_define_colormap”, so you do not need to change your .hluresfile if you just want to change the color map for a single plot. Create NCL scripts The basic outline of any NCL script will look as follows: load external functions and procedures begin end ; Open input file(s) ; Open graphical output ; Read variables ; Set up plot resources & Create plots ; Output graphics For example, let’s create a script to plot Surface Temperature, Sea Level Pressure and Wind as shown in the picture below.
