<p>Hi Dave,</p>
<p>If you use ncl_filedump to look at your data you will see this
listed for sst:</p>
<p> short sst ( time, latitude, longitude )<br>
long_name : Sea surface temperature<br>
units : K<br>
add_offset : 289.9202167899307<br>
scale_factor : 0.0006308732635179985<br>
_FillValue : -32767<br>
missing_value : -32767<br>
</p>
<p>Notice there is an offset and a scale factor in the data record
for sst. I believe you will need to add the offset and multiply by
the scale factor to get back to actual temperature in kelvins.</p>
<p>Good luck.</p>
<p>Jim<br>

<div>Dear NCL Users,<br>
<div>I plotted sst on a local scale using NCL. The result for
the sst variable are way too high. Plotting the same data
with CDO and using ncview, the results for the sst variable
are in the values to be expected. In CDO, the variable sst
has a range from 297.274K to 300.189K but in NCL the plotted
graph showed a range from about 12000 to 16000. Could our
most esteem NCL experts help me out here? I would be
grateful for your help.<br>
<div>Attached are the file, script and the corresponding
plot.</div>
<div>I am using NCL version 6.4.0<br>
<div>Data is from ERA5</div>
<div><br>
<div>Best regards</div>
