<font face="Times New Roman">Hi Martin,<br>
<br>
I'm not sure about this, but according to the Appendix D. of the
CF-conventions <br>
<br>
(see:
<a class="moz-txt-link-freetext" href="http://cf-pcmdi.llnl.gov/documents/cf-conventions/1.5/cf-conventions.html#dimensionless-v-coord">http://cf-pcmdi.llnl.gov/documents/cf-conventions/1.5/cf-conventions.html#dimensionless-v-coord</a>
)<br>
<br>
</font><font face="Times New Roman">the formulas are different
enough, at least for some variants of sigma coordinates, that the
script will unlikely work. </font><br>
<br>
Anyway, let us know what you find out.<br>
cheers,<br>
Karl<br>

<pre wrap="">I think Gary's suggestion will work -- I should have said from "sigma-height" levels to height (it is ocean data that the user is trying to deal with), so it should be the same as getting to pressure from the usual pressure based sigma system. I'll check it and let you know,
cheers,
Martin

doesn't that return pressure levels? seems they're requesting height

Hello,
does anyone have a robust and portable script (e.g. NCL) to interpolate CMIP5 data from sigma levels to height levels? A user has asked for advise on this, and it would make sense to provide something which exploits the uniformity provided by the CMOR2 data model,
See
