The ftp directory structure follows the [ CMIP5 DRS convention ](http://cmip- pcmdi.llnl.gov/cmip5/docs/cmip5_data_reference_syntax.pdf) , with one exception:
////<time_frequency>//<CMOR_ta ble>///<file_version>/<file_name>
For example:
output1/BCC/bcc-csm1-1/decadal2001/mon/atmos/Amon/r1i1p1/hur/1/hur_Amon_bcc- csm1-1_decadal2001_r1i1p1_200201-201112.nc
The exception to the DRS convention is the <file_version> field, which is an integer number starting at 1. The larger the file version number, the more recent the file. For example, if there are directories numbered 1,2, and 3, then the file(s) in directory 3 are the latest versions.The DRS 'dataset version number' does not appear in the ftp directory structure.
