Jeff,
Thanks for your suggestion for preparing a control file. I browsed the
site given by Jennifer and started preparing an xdfopen control file
below
But I will need your help to fill in the vars. how do I get these and
do I have to put in the whole of them?
What I get from "ncdump -v Times wrfout_d01_2012-01-27_00:00:00" is
alos below (a small part not to congest the mail)
DSET ^wrfout_d01_2011-11-19_00:00:00
TITLE WRF output Rwanda
