What I did for an experiment was write a fortran program that forced changes in the LU_INDEX category located in the wrfinput files (based on the i,j of the points I wanted to modify). This has to be done after real.exe is run. Modifications to the geo_em files can be done, but are lost during the metgrid.exe and real.exe steps.<div>
<br></div><div>Otherwise you can change some land use effects such as albedo or roughness lengths in the LANDUSE TBL in the WRFV3 run directory, but those changes are applicable to all the points of the land use category.</div>

Hi! All<br>
<br>
I am going to investigate Climate Sensitivity of Land Use and Land<br>
Cover changes over Southern Ontario, Canada using WRF. I am a novice<br>
WRF user (started learning WRF from October 2009). Would you please<br>
help me by providing some information about LULC change experiment<br>
using WRF.<br>
<br>
I would like to see the climate sensitivity by extending an existing<br>
Urban area or turning a particular type of vegetation into another type.<br>
<br>
How can I change the Land Use and Land cover over a selected domain?<br>
Which file I should change?<br>
<br>
I look forward to hearing from you.<br>
<br>
Thanks in advance<br>
