Time slice

Choose a common time slice out of all the CMIP5 sea ice concentration files in our directory:

import cmipdata as cd
ens = cd.mkensemble('sic_OImon*')
ens = cd.time_slice(ens, start_date='1979-01-01', end_date='2013-12-31')

where start_date and end_date are given in YYYY-MM-DD format. This will create a new set of files covering the chosen period, and by default will delete the original input files (to prevent this specify delete=False). Any realizations that do not contain the full requested date range will be dropped from the ensemble (and deleted by default).
