The python netcdf module is finally available for testing and use.

Please check the following url for information:

<http://snow.cit.cornell.edu/noon/ncmodule.html>

Quick overview:

Python is an interpreted, object oriented language that is supported on a
wide range of hardware and operating systems.  Information and sources
can be obtained from <http://www.python.org/>

The netcdf bindings allow easy creation, access and browsing of netcdf files.

The bindings also use the udunits library to do unit conversions.

An example of opening a netcdf file, reading a value, changing it and
saving the file:

>>>
# python
Python 1.3 (Oct 26 1995) [C]
Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
>>> import nc
>>> file = nc.open('test.nc',nc.WRITE)
>>> file.list_dim()
[('time', 0), ('len', 10)]
>>> y = file.var('y')
>>> y[0] = range(10)
>>> y[0]
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> y[0] = [0, 1, 2, 3, 99, 5, 6, 7, 8, 9]
>>> y[0]
[0, 1, 2, 3, 99, 5, 6, 7, 8, 9]
>>> file.close()
>>> file = nc.open('test.nc')
>>> y = file.var('y')
>>> y[0]
[0, 1, 2, 3, 99, 5, 6, 7, 8, 9]
>>> file.close()

Give it a try.
