python-meteorology first post, interesting Python projects

[Esben Stigård Nielsen]

Hi,

I will initiate this group with a listing of Python projects relevant
for satellite data applications.
Of the top of my head:

Pyproj, Python bindings to Proj.4: http://code.google.com/p/pyproj/
h5py, Python HDF5 library: http://h5py.alfven.org/
netCDF4, Python netcdf4 and netcdf3 library:
http://netcdf4-python.googlecode.com/svn/trunk/docs/netCDF4-module.html
Python-bufr, Python bindings to ECMWF BUFR-decoder:
http://code.google.com/p/python-bufr/
Pydap, Python OPeNDAP implementation: http://pydap.org/

Please feel free to extend the list.

Best regards
Esben

I'd also think of

- numpy
- scipy
- matplotlib

and in addition to the data formats

- pytables (another HDF5 wrapper)

Hi Everyone,

some more suggestions might be:
-PIL (Python Imaging Library)
-BEAT (Basic Envisat Atmospheric Toolbox project) http://www.stcorp.nl/beat/
and its interfacing layer CODA.

Also in addition to the already mentioned Python-bufr module
http://code.google.com/p/python-bufr
(which uses c-code to interface some selected routines from the ECMWF
bufr library to python)
there are 2 alternative approaches:
-pybufr-ecmwf http://code.google.com/p/pybufr-ecmwf/
uses the f2py tool from numpy to build a full interface to the ECMWF
bufr library, so including the writing routines as well.
-pubufr http://code.google.com/p/pybufr/
tries to implement bufr reading functionality using pure python.

Finally, maybe it would be usefull to compile these contributions in a
single list. A wiki-page would be nice, although I don't know if that
is possible for a group like this.

best regards,

Jos de Kloe, KNMI.

The basemap addition to matplotlib is probably helpful for quite a few
of us.
http://sourceforge.net/project/showfiles.php?group_id=80706&package_id=142792/&abmode=1

Be sure to install PIL as well, this enables NASA's Blue Marble as a
background for worldplots in matplotlib with basemap.

SciPy already implies using iPython, but it is worth to emphasize
this.

For code quality and bug prevention, I'd add PyLint to the list
( http://www.logilab.org/projects/pylint ), and a Source Code
Management system (Mercurial). I combine them using Eclipse, but some
have a rather strong dislike for that system.

Just to add the link:
http://www.pytables.org/moin
PyTables is one of the cleanest interfaces for python I've seen so
far. Not so helpful if you are familiar with the C or Fortran
interface, but a pleasure to work with if you enjoy Python.

Not a dataformat, I've seen them far too often: IDL 'save' files:
http://idlsave.sourceforge.net/

Best,

Maarten Sneep
