original wrf output format of the variable Times is year-month-day_hour:minute:sec and when I apply CDO with splitlevel, seltime, merge, etc. Times format change to fractionary format, ex:
2007-12-03_14:00:00 change to 20071203.5416667.
how can I fix this problem? how can I format again Times variable to date_hour format after CDO use?
