<div dir="ltr">Hello Koichi,<div><br></div><div>Thanks for your email and detailed explanation, as well as I am sorry to hear the inconveniences you have been having!</div><div><br></div><div>As you already mentioned, NCL is in maintenance mode, and we are doing our best to provide support for it (prioritizing Conda installation related issues). However, even those types of issues are leading us to spend days most of the time, sometimes without finding a solution. Since we have several other toolkits in our GeoCAT stack that need to be planned, developed, deployed, and maintained in our daily workflow, sometimes, we can't even check and respond to NCL issues even though we wouldn't like to oversee any support ticket such a vibrant community has. </div><div><br></div><div>With all that being said, we are noting down such issues for being addressed in a future bug fix release (the date of which is not current as of today), if the community itself does not resolve the issue with the help of other users/developers. </div><div><br></div><div>The community developers are more than welcome to offer any solutions/bug-fixes to such NCL issues.</div><div><br></div><div>I hope this helps understand our situation and the tool's maintenance plan.</div><div><br></div><div>Regards,</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, Aug 22, 2021 at 11:06 AM Sakaguchi, Koichi via ncl-talk <<a href="mailto:ncl-talk@mailman.ucar.edu">ncl-talk@mailman.ucar.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<p class="MsoNormal"><span style="font-size:11pt">I found a bug in the ncl function taper (and taper_n) such that when the option 1 is chosen the function does not copy all the values of the input array to the output array, except for the portions that are
tapered. In my environment (NERSC and PNNL computing facilities), the uncopied values in the output array are all zero. This bug had a serious impact on my work.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt">The function works correctly when option 0 is chosen. This difference arises because the output array is not initialized properly in the underlying fortran code (taper.f) when option 1 is selected.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt">I provided more details in the NCL github issues<u></u><u></u></span></p>

<p class="MsoNormal"><span style="font-size:11pt">I posted a bug report about a month ago following
<a href="https://www.ncl.ucar.edu/Support/posting_guidelines.shtml" target="_blank">https://www.ncl.ucar.edu/Support/posting_guidelines.shtml</a>, but no responses have been provided, so I am reporting here in the ncl-talk. I see a few even older postings without responses
from the developers there... I am aware that NCL is in the maintenance mode without further development, but I think more close and regular attention should be paid to the issues posted on NCL github because NCL is still very widely used.
