Modules for Scientific Computing and Visualization
SciPy/NumPy
pylab
Matplotlib/pylab Plotting functions with a high degree of Matlab compatibility
http://matplotlib.sourceforge.net/basemap/doc/html/ Matplotlib Basemap
Import the Basemap module
from mpl_toolkits.basemap import Basemap
GDAL
GDAL - Geospatial Data Abstraction Library for various satellite data formats
To enable GDAL use
module load gdal
from osgeo import gdal
PyNGL PyNio
PyNGL/PyNIO Python interface to NCAR Command Language
- Scientific visualization and data formats (netCDF, HDF, GRIB etc.)
To enable PyNGL (on ZMAW Linux ia32/x64 and solaris10) you have to type
module load PyNGL/1.2.0
Please note, that Nio should be on the top of the list, e.g.
import Nio from osgeo import gdal import pylab as pl
Python Interface to GrADS
RPy
RPy (R from Python) Statistical computing and graphics
F2PY: Fortran to Python interface generator
Calling Fortran code from python is easy!

Python and Climate
Download (try this at home)
A basic system for scientific computing consists of Python, ipython, numpy/scipy, pylab, and an editor of your choice
Editor (a nice editor for Windows user, if you don't like to install xemacs)
The python(x,y) distribution contains all that above.
