<p>To whom it may concern,</p>

<p>I am trying to use this function <span style="font-size:12pt">wrf_user_ll_to_ij on a moving nested domain but found things problematic for moving nested domains. Here is the prototype of this function:</span></p>
<p><span style="font-size:12pt"></span></p>
<pre style="margin-top:0px;margin-bottom:0px;padding:0px;font-size:13.3333px;line-height:12pt;font-family:courier;border-style:solid;border-width:0px 0px 15px;border-color:transparent"> function wrf_user_ll_to_ij (
file_handle : file or list [list added in V6.0.0],
lon : numeric,
lat : numeric,
opt : logical
)</pre>
The first statement is the file that needed to be handled. But for a nested domain output, each time step has a different domain region. Then how do we represent each time step for this first statement? For example. I have this file <span>wrfout_d02_2005-08-20_18:<wbr>00:00
which include 12-time steps . When I want to extract one certain point from all the time steps, how do I define the first statement?</span>
<div>For example, if<br>
