Re: 'units' attribute of coordinate array

Hi Wenshan,
I see you have 3 printVarSummary statements in your code. Please send ncl-talk the output from these statements. At first glance, I do not see anything wrong. As another ncl-talk contributor has posted, as it is Christmas Eve and tomorrow is Christmas, a reply from someone on the list is not likely until the 26th at the earliest.
Thanks, Adam
