Hi Kunal,

because not knowing your data, please take a look at:

https://www.ncl.ucar.edu/Document/Graphics/error_msg.shtml*
*
go to  ' Coordinate Variables do not have correct units attribute*'

* or just search (google) the first part of your error message. It will 
give
you the important links straight forward.

Bye,
Karin
