Some people have reported that the Mac FTP client has trouble with files bigger
than 4GB.  If you look at the monthly composites directory and the files there
appear to be around 500-600MB rather than ~4.5GB, you are affected by this
problem.  If you attempt to download, you'll get ~500MB corrupt files.

We suggest either downloading another FTP client (and will update this file
with recommendations if we're told of them) or use the Mac command line, which
appears not to be affected.  To use the command line:
 - Open a terminal, type (or cut & paste):
 ftp ftp://oc-cci-data:ELaiWai8ae@ftp.rsg.pml.ac.uk/occci-v1.0/geographic/netcdf/monthly/all_products/
 - You can then use standard FTP commands, like:
    "cd DIRECTORY" to change directory
    "ls" to list the contents of the current directory
    "get FILENAME" to download a specific file
