<p>Hi Mr. Shea,</p>
<p>the variable out1 is the result of a interpolation made by roms_3d_interp (function of Roms_utils.ncl - <span><span><a href="https://www.ncl.ucar.edu/Applications/Scripts/ROMS_utils.ncl" target="_blank">https://www.ncl.ucar.edu/<wbr>Applications/Scripts/ROMS_<wbr>utils.ncl</a></span></span>). If you looking for the temp values in the problem region in original file (nested_avg_19811216_LEILANE.<wbr>nc) you will see this file is fine, I checked with Ncview, Ferret, Matlab and Ncdump. Because this I guess that problem is in my Roms_utils.ncl</p>
<p>Thank you <span><span>for trying to help.</span></span></p>

<p><span><span>I had to make 2 modifications to be able to use this script:<br></span></span></p>
<p><span><span>1 - comment some lines: 5-133 - <span><span>I do not know</span> <span>why, but</span> <span>the script</span> <span>does not run</span> <span>if these</span> <span>lines are</span> <span>uncommented</span><span>.</span></span><br></span></span></p>
<p><span><span>2 - add another parameter to call function roms_3d_interp: in my case the variable h (Final bathymetry at RHO-points) and the variable that will be interpolated (temp: time-averaged potential temperature) don't be in the same file. h is in </span></span>my <strong>grid file</strong> and temp is in the <strong>output model file</strong>. So, <span><span>I added</span> <span>a new parameter</span> <span>when I calling</span> <span>the function - the file_grid</span></span>:</p>
<p><span style="color:#808080">137</span> <span style="color:#ff0000">function</span> roms_3d_interp( file_handle, <strong>file_grid</strong>, var:string, \<br><span style="color:#808080">138</span> rec:integer, z:numeric )</p>
<p>and I changed the lines 166-176 and 208: <span><span>to call</span> <span>the file</span> <span>that contains the variable h</span></span></p>
<p><span><span><span style="color:#808080">166 </span>if(typeof(file_grid).eq."file"<wbr>) then<br><span style="color:#808080">167 </span> ISFILE = True<br><span style="color:#808080">168 </span> nc_grid = file_grid<br><span><span><span style="color:#808080">169 </span></span></span> else if(typeof(file_grid).eq."list"<wbr>) then<br><span><span><span style="color:#808080">170</span></span></span> ISFILE = False<br><span><span><span style="color:#808080">171 </span></span></span> nc_grid = file_grid[0]<br><span><span><span style="color:#808080">172</span></span></span> else<br><span><span><span style="color:#808080">173 </span></span></span> print("roms_interp_3d: error: the first argument must be a file or a list of files opened with addfile or addfiles")<br><span><span><span style="color:#808080">174</span></span></span> return<br><span><span><span style="color:#808080">175</span></span></span> end if<br><span><span><span style="color:#808080">176</span></span></span> end if</span></span></p>

<p><span style="color:#808080">208</span> if(isfilevar(<strong>nc_grid</strong>,"h"))</p>
<p> </p>
<p>After this function a region with constant temperature is interpolated with missing values. The figures and the scripts are attached. The files: nested_avg_19811216_LEILANE.nc and mesh_donor_grd_004nested_</p>
<div>LEILANE.nc are in the FTP server. My NCL version is 6.3.0.</div>
