<br>
</p>
<p>
<span style="font-family:Georgia;font-size:16px;">Millions of thanks for the clarification</span><span style="font-family:Georgia;font-size:16px;">. I could use the 'simpne' for integral of T(t,x,y). </span>
</p>
<p>
<span style="font-family:Georgia;font-size:16px;"><br>
</span>
</p>
<p>
<span style="font-family:Georgia;font-size:16px;">Could you please tell me How can I use this function for <span style="font-family:Georgia;font-size:16px;white-space:normal;">integral y.T(t,x,y)</span>?</span>
</p>
<p>
<br>
</p>
<p>

<div>
The documentation for <a href="http://www.ncl.ucar.edu/Document/Functions/Built-in/simpne.shtml"><b>simpne </b></a>states it uses 3 points<br>
</div>
<div>
<b>simpne</b> - Integrates a sequence of unequally or equally spaced points using Simpson's t<b>hree-point formula</b>. <br>
</div>
<div>
<br>
</div>
<div>
Hence: 2 points will not work.

Possibly: the <a href="http://www.ncl.ucar.edu/Document/Functions/Built-in/ftcurvi.shtml"><b>ftcurvi</b></a> could be used

<p>
<span style="font-family:Georgia;"><span style="font-size:16px;">I want to integrate latitude (y) over the temperature (T(x,y)). I tried to use the function "simpne" but It gives me an error which is "Must have three or more non-missing values". </span></span>
</p>
<p>
<span style="font-family:Georgia;"><span style="font-size:16px;"><br>
</span></span>
</p>
<p>
<span style="font-family:Georgia;"><span style="font-size:16px;">Could you please suggest me an another way to do the integration?</span></span>
