<div dir="ltr"><font color="#000000">Dear all,</font><div><font color="#000000">Thank you for your suggestions. However, the problem still exists. I checked the files individually and found out nothing wrong with them. I run the script for each year separately and did not get the warnings, but once run the script for all the years together the warnings appear. I attached the output from tests that Dave has suggested. </font></div><div><font face="arial, sans-serif" color="#000000">NCL version:<span style="font-size:14px;font-variant-ligatures:no-common-ligatures"> 6.6.2 </span></font></div><div><font color="#000000" face="arial, sans-serif"><span style="font-size:14px;font-variant-ligatures:no-common-ligatures">Computer system: macOS Mojave, version 10.14</span></font></div><div><font color="#000000" face="arial, sans-serif"><span style="font-size:14px;font-variant-ligatures:no-common-ligatures">Best wishes,</span></font></div><div><font color="#000000" face="Menlo"><span style="font-size:14px;font-variant-ligatures:no-common-ligatures"><br></span></font></div>
