That's good news Zilore. I am really perplexed as to why wrf_user_getvar works, but a->XLAT does not - both should be valid. In any case, I'm happy to hear you have a way forward!<div><br></div><div>Rick<br><br>On Friday, August 6, 2021, Zilore Mumba <<a href="mailto:zmumba@gmail.com">zmumba@gmail.com</a>> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>Rick , You have solved my problem.

It would seem that the file is somehow corrupt, although I don't understand how or why. Are you able to open it with some other tool, such as "ncdump"? Can you simply discard it from your analysis? If it's not too large and you can send it to me, I will take a look, although obviously that won't change the outcome if it is indeed corrupt.</div><div><br></div><div>Rick<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Aug 6, 2021 at 2:57 AM Zilore Mumba via ncl-talk <<a href="mailto:ncl-talk@mailman.ucar.edu" target="_blank">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"><div dir="ltr">Hello,<div>I need help opening a WRF output file.
