<div dir="ltr">I have had this problem occasionally. Usually it's because the undefined values in your .nc file is set as -8e+38. You can change the default undefined values of the .nc file to be 99999.0, as per your .ctl file, using programs such as CDO. You could also change your .ctl file UNDEF parameter to -8e+38 and see if that works for you.</div>

<p dir="ltr">As per your ncdump output, you have 721 lat points and 721 lon points. But in your description file you specified 1637 lon points and 200 lat points. Please verify it.<br>
