[Glenn Carver sent the appended note for the netcdfgroup mailing list.]

I thought I would write highlighting the excellent compression of netcdf
files offered by the new compression tool 'bzip2'. bzip2 is a high quality
data compressor which is freely available. The website is :
"http://sourceware.cygnus.com/bzip2/";

As an example with some of my netcdf files 200Mb uncompressed, bzip2
squashes these down to 20Mb whereas gzip can only manage 160Mb (both on
default settings).

I hope this is of use to people on the netcdf mailing list.

  Glenn
