<p style="font-family: bookman old style, new york, times, serif;">A couple of points I should mention:</p>
<p style="font-family: bookman old style, new york, times, serif;">1. I installed conda and NCL on two different servers, but the same issue occurred.</p>
<p style="font-family: bookman old style, new york, times, serif;">2. This issue also happened, for example, when I tried to read "PRES_P0_L1_GLL0" from sp files on ECMWF.</p>
<p style="font-family: bookman old style, new york, times, serif;">Any help would be greatly appreciated. The script and sample file are attached.</p></div></div><div class="ydp2bc85b9esignature" style="font-family: bookman old style, new york, times, serif;"><div dir="ltr" style="font-family:old times, serif;font-size:16px;"><div><div dir="ltr" style="color:rgb(0, 0, 0);font-family:old times, serif;font-size:16px;"><i><font size="2">-----------------------------------------------------------------------------</font></i></div><div dir="ltr" style="color:rgb(0, 0, 0);font-family:old times, serif;font-size:16px;"> <div><div style="color:rgb(0, 0, 0);font-family:serif;font-size:16px;"><div dir="ltr"><i><font size="2">Best regards,</font></i></div><div dir="ltr"><i><font size="2">Ehsan Taghizadeh</font></i></div><div dir="ltr"><i><font size="2">Ph.D. Student in Natural Resources & Environmental Studies (NRES),</font></i></div><div dir="ltr"><i><font size="2"> University of Northern British Columbia (UNBC)</font></i></div></div></div></div></div></div></div></div></body></html>
