All:
I have put a small tar file on my web site which demonstrates how to
create a Python/NCL program where Python is used to create the NCL
script. This is using a very simple library that Ethan Alpert wrote for
me a while back at SCD.
You can download it at: http://www.nssl.noaa.gov/~lwicker/testncl.tar
I am simply using one of the demonstration scripts to show how you build
a simple program.
Now, please check for where your GSUN is defined, the testncl.py script
defines where it is as part of an ncl load statement.
Also, remember, the ncl.so module is the new library and it is based on
Python2. So you need to be running that and also be on a RH Linux
system. I do not know if other Intel-based Linux systems will work.
Here is a quick example of using the lib:
$ python2
>>> import ncl
>>> ncl.command("a = 17.0")
(0) 17
>>>ncl.command("print(a)")
Variable: a
Type: float
Total Size: 4 bytes
1 values
Number of Dimensions: 1
Dimensions and sizes: [1]
Coordinates:
(0) 17
Merry Xmas, and enjoy. Not sure if this adds a lot to what you already
have.
