Scripting in ISL (IDV Scripting Language)

Making your own Images--Example Script in ISL or Text
NOTE: ISL stands for "IDV Scripting Language" and this file extension
is needed for IDV to execute tasks in Linux. More advanced techniques
can be found in the recently developed Jython script below.

Scripting in Jython

All functions in the IDV may be called through Jython scripts. This
language provides much more flexibility in specifying parameters
for displays of atmospheric data. The example script at right uses
an MIT circulation model as the data source. The script then takes
various inputs from the user and produces an image of horizontal
potential temperature and accompanying wind vectors.
A web interface will run the script and produce images from the
user's choices. A wide range of display options are documented
throughout the script's code. NOTE: This script can always be
improved, hence there are some comments of this nature too.

Jython Script (2dhzt.py) - Horizontal Slice of Pot. Temp. & Wind Vectors

The following Linux command runs the script:

runIDV -islfile 2dhzt.py < Input

The Jython script (in the link above) takes in arguments to plot potential temperature contours and arrows for wind vectors.
This set of inputs is described below:
      0 = Selects only one time frame (no animation)
      30 = Selects time frame 30 (indexed from 0 to 60)
      theta,color,y,---, = Data Field, Contour type (line or color),Wind Vectors?(y/n),Colortable (for line contour)
      red,0,3,14, = Vector: Color, Skip, Width, Length
      2,0,-75,30,2,n, = Contour: Interval, Base, Minimum, Maximum, Width (for line contour), Labels?(y/n)
      35,23,1.95, = Azimuth, Tilt, Zoom-Factor
      7 = Selects data from level 7 (indexed 0 at top, 15 at bottom)

The resulting image, from the arguments in Input, is displayed below:

This is the view from the terminal window as the script is
run with the input arguments from Input:

Here's another example with line contours, using the arguments in Input2:

Click on the image below to see a loop, generated with Input3.
Note that the 1st line of Input3 is a 1, which creates a loop.
The 2nd and 3rd lines are the first and last frames respectively.
