In order to do any vertical interpolation, you would need a three dimensional heat flux variable. You're trying to use a one-dimensional interpolation routine, which is really meant for one vertical column in a three-dimensional variable. If you had a 3D heat flux variable, you would want to use wrf_interp_3d_z or wrf_user_intrp3d. </div><div><br></div><div>However, since all you have is the 2D heat flux at the surface, I think you're going to have to resort to the radiation equations for calculating the 20 m, 30 m, and 100 m values. Off the top of my head, I don't think NCL has anything built in to do this for you, so you'll probably have to implement this yourself. It's been a long time since I took radiation, so if all this is new to you, start with the concept of 'optical depth' and go from there. Maybe others have better suggestions here.</div><div><br></div><div>Bill</div></div><div class="gmail_extra"><br><div class="gmail_quote"><div><div class="h5">On Mon, Jul 25, 2016 at 1:51 AM, ananya sritawan <span dir="ltr"><<a href="mailto:ananbeam76@gmail.com" target="_blank">ananbeam76@gmail.com</a>></span> wrote:<br></div></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div class="h5"><div dir="ltr"><div style="font-size:12.8px">Dear all </div><div style="font-size:12.8px"><br></div><div style="font-size:12.8px">I have been working on WRF-LES and now I am trying to get a data at a specific height says 20m 30m 100m.</div><div style="font-size:12.8px">The data that I want to obtain is sensible heat flux from my wrfout at 20m 30m and 100m.
