WRF4.3 BEP+BEM set up

[jli628]

Hi,

I am using WRF4.3 to examine the impact of urbanization on mesoscale convective systems. My current domain contains some regions of the US and Canada. I use "nlcd2011_9s+default" static data in the namelist.wps. According to my understanding, it is a combination of NLCD2011 for the US and MODIS for other regions, which is confirmed by the "geo_em.d01.nc" file. Now, there are 5 urban classes:
13 Urban and Built-up
23 Developed Open Space
24 Developed Low Intensity
25 Developed Medium Intensity
26 Developed High Intensity.

13 is for MODIS for non-US regions, and 23-26 are for NLCD2011 for the US regions. I am wondering whether BEP+BEM can handle such a case. Will it produce correct results? Thanks.

Hi,
When NLCD and MODIS are combined to provide landuse type over a specific region, NLCD has the top priority, i.e., it is used to produce landuse over areas covered by NLCD. In areas not covered by NLCD, MODIS will be used to produce landuse type. This is why we have five 5 urban classes. BEP+BEM is able to handle this situation.
