NCL: NOGAPS (Wind Forcing)

How these scripts work

Each script is a stand alone entity that produces a particular type of plot, vector only, contour only, vectors on contours, panels etc. Your first task is to determine what type of plot you want. All of the scripts are located in:
"/u/NOGAPS/NCLscripts".

At the top of each script, is an area where the user is allowed to make selections, such as which variables, which periods etc. to plot. These are your scripts, so you certainly are allowed to change the underlying NCL code. The current format was designed so that non-NCL users can use the scripts.

The following is an example of the user's parameters for the contour only script

   ; -1 means let NCL determine range of data. Note fluxes have 
   ; hard-wired ranges to ensure colormap centered on zero.  
    mincn      =  -1        ; min contour
    maxcn      =  -1        ; max contour
    cnint      =  -1        ; contour interval
   ; 
    linesOn    = False      ; turn on contour lines
    centerLon  = 0          ; choose any value

All these scripts call func_nogaps.ncl

global_nogaps_con.ncl: Creates single pane images of scalar variables, one period per pane. As many periods as desired may be chosen. Each period is a separate frame in a postscript or X11 file.

global_nogaps_vec.ncl: Creates single pane images of vector variables, one period per pane. As many periods as desired may be chosen. Each period is a separate frame in a postscript or X11 file. Choose between wind and curl.

global_nogaps_vec_con.ncl: Creates single pane images of vector over scalar variables, one period per pane. As many periods as desired may be chosen. Each period is a separate frame in a postscript or X11 file.

global_nogaps_con_panel.ncl: Creates panel plots of scalar variables, up to four plots per page. This example demonstrates the configuration of four plots.

global_nogaps_vec_panel.ncl: Creates panel plots of vector variables, up to four plots per page. This example demonstrates the configuration of three plots.

global_nogaps_vec_con_panel.ncl: Creates panel plots of vector over scalar variables, up to four plots per page. This example demonstrates the configuration of 2 plots.
