Hi,
Can anyone list what file compression methods THREDDS can support when
accessing data files, i.e. can a data file be stored in a compressed
format, such as bzip2, and yet THREDDS can still access the file and
extract data.
Kind regards,

If the URL ends with a with ".Z", ".zip", ".gzip", ".gz", or ".bz2", the
file is assumed to be/*compressed*/. The netCDF-Java library will
uncompress/unzip and write a new file without the suffix, then read from
the uncompressed file. Generally it prefers to place the uncompressed
file in the same directory as the original file. If it does not have
write permission on that directory, it will use thecache directory
