You need to change the ‘units’ field in your variable declaration; instead of ’99’ you need a comma-delimited set dimensions, perhaps something like “t,y,x”. Look in the output of ncdump for the dimensions of the precip variable.

Is it possible to get grid distance value inside GrADS script somehow?<br>

<br>
Best regards and thanks!<br>
