<p class="MsoNormal" style="margin-bottom: 12pt;">John,</p><div class="im"><br>
I get the WRF WPS projection information as following:<br>
<br>
e_we
= 98, 118,<br>
e_sn
= 70, 103,<br>
geog_data_res =
'10m','2m',
<br>
dx = 30000,<br>
dy = 30000,<br>
map_proj = 'lambert',<br>
ref_lat = 34.8,<br>
ref_lon = 113.7,<br>
truelat1 = 30.0,<br>
truelat2 = 60.0,<br>
stand_lon = 113.7,<br>
<br>
My key point here is : CMAQ domain is a little bit smaller than WRF domain
because we eliminate the outside columns and rows to diminish lateral effects.
So my WRF domain has 98*70 grids while my CMAQ domain has 94*67 grids.<br>
<br>
so the question is: how to set (isize, jsize) and (iref, jref) in pdef
variable? I am confused.<br>
