Hi Saji

If "y" already exist and has named dimensions

    y(time,LAT,LON)

and "x" is

    x(time,lat,lon)

the

    y = x

will result in the above error message.

====

Variable: y
Type: float
Total Size: 96 bytes
            24 values
Number of Dimensions: 3
Dimensions and sizes: [time | 2] x [lat | 3] x [lon | 4] <=== Note
it has the dim names of "x"
Coordinates:
========================================================

To avoid the message

      y = (/ x /)

The will result in "y" retaining its original named dimensions.
