<p class="MsoNormal">Hi ncl’ers,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a 3d array for the full model height levels, say, zfull(nlat,nlon,nlevs). I want to calculate the midpoints of the height levels of the full model heights and put it into a new array, say zhalf(nlat,nlon,nlevs-1). The following
code:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> do i=0,nlevs-2<o:p></o:p></p>
<p class="MsoNormal"> zhalf(:,:,i) = 0.5 * (zfull(:,:,i)+zfull(:,:,i+1))<o:p></o:p></p>
<p class="MsoNormal"> end do<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">or, the following code:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> zhalf = 0.5*( zfull(:,:,0:nlevs-2) + zfull(:,:,1:nlevs-1) )<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">generates some data, but I don’t know and think what I am doing is right since the half height levels are strange. How can I calculate the mid-points of height levels of a 3d array of height levels?
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thank you for your help.<o:p></o:p></p>
