[Numpy-discussion] Request for porting pycdf to NumPy

+1 for Whitaker's package.

The new location of the package is:


I use netcdf for everything I do, and so I checked out all of the  
packages in detail.  All follow a similar API, although there are  
very minor differences that will catch you if you are not careful  
(like writing a single character).

Although this is (austensibly) made for netcdf4, Whitaker's package  
works well both reading and writing netcdf3 files.  It also has  
support for stitching together multiple files.  It also has support  
for compression of numpy4 data (as well as all of the other cool  
netcdf4 features).  The only disadvantage is that netcdf4 is a bit  
harder to install than netcdf3 -- primarily because the user must  
first install hdf.  However, recent versions work fine on all the  
platforms I use (Mac and Redhat).

Clearly this is the way to go.
