<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I’m running a version of the ARW (v2.1.2) coupled to a
land surface model software, which is invoked within the module_surface_driver.F
file beginning with the first model timestep (as well as every subsequent model
timestep) instead of calling one of the standard LSMs. The coupled system
is set up such that the t=0 wrfout file is written prior to the call to the special
LSM routine. </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>What I’d like to do is to re-write the t=0 wrfout file
after the LSM routine is called in the first timestep, so that the data obtained
from the LSM call over-ride the initial data in the t=0 wrfout file. </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Does anyone have a suggestion on how best to re-write the
t=0 wrfout file with new data after the first timestep has already been called?
</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I suppose another (possibly simpler) option might be to
write out the WRF data after 1 timestep and then stop the model at that point.</span></font></p>
