[ncl-talk] NCL coordinates erroe

[Kunal Bali]

After editing the scripts according to you , the dimensions size not
showing [lon | 421] ??

How to fix it ??

its shows like

*Variable: lat (coordinate)*
Type: float
Total Size: 1252 bytes
            313 values
Number of Dimensions: 1
Dimensions and sizes:    [lat | 313]
Coordinates:
Number Of Attributes: 9
  scale :    0
  stride :    0.08333334
  gridReference :    edge
  standard_name :    latitude
  endValue :    26
  units :    degrees
  scaleType :    linear
  startValue :    -0.08333065
  size :    313
