Hi,<br>
In WRF you can give explicitly the values for vertical levels, to do this you need add eta_levels values like this:<br>
<br>
<span style="font-family: courier new,monospace;"> &domains</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;"> eta_levels = 1.0000, 0.9960, 0.9940, 0.9920, 0.9900,</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;"> 0.9880, 0.9850, 0.9820, 0.9780, 0.9740, 0.97, 0.965,</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;"> 0.96, 0.949, 0.937, 0.924, 0.909,</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;"> 0.892, 0.873, 0.851, 0.826, 0.798,</span><br style="font-family: courier new,monospace;">

<div><font face="ËÎÌå" size="2"> I am trying to run WRF ideal case
em_quarter_ss, and I set "s_vert=1, e_vert=41 " in namelist.input file. But I
want to know the sigma value of each level, does anyone know how does WRF model
generate sigma values according the total number of vertical levels? What
is the default sigma value according vertical level settings?</font></div>
