How to make sure my URBAPARM.TBL is read

[Kecheng Zhao]

I used Python code to replace urban category 13 in the geo_em file with 31 (low-density residential), 32 (high-density residential), and 33 (commercial). I also made corresponding modifications in LANDUSE.TBL and VEGPARM.TBL.

For example, I added entries like these:

• 31, 10., .10, .97, 80., 3., 1.67, 18.9e5, 'Low Intensity Residential'
  32, 10., .10, .97, 80., 3., 1.67, 18.9e5, 'High Intensity Residential'
  33, 10., .10, .97, 80., 3., 1.67, 18.9e5, 'Commercial'

And also definitions like:

• LOW_DENSITY_RESIDENTIAL
  31
  HIGH_DENSITY_RESIDENTIAL
  32
  COMMERCIAL
  33

After setting surface_input_source to 3, my wrfinput file also contains land use categories 31, 32, and 33.


So, I started running WRF, but I found the following two sections in rsl.error:

• USING DEFAULT URBAN MORPHOLOGY
  USING DEFAULT URBAN MORPHOLOGY
  USING DEFAULT URBAN MORPHOLOGY

and

• USING DEFAULT URBAN MORPHOLOGY
  WARNING, FRC_URB2D = 0 BUT IVGTYP IS URBAN
  WARNING, THE URBAN FRACTION WILL BE READ FROM URBPARM.TBL
  USING DEFAULT URBAN MORPHOLOGY
  WARNING, FRC_URB2D = 0 BUT IVGTYP IS URBAN
  WARNING, THE URBAN FRACTION WILL BE READ FROM URBPARM.TBL
  USING DEFAULT URBAN MORPHOLOGY
  WARNING, FRC_URB2D = 0 BUT IVGTYP IS URBAN
  WARNING, THE URBAN FRACTION WILL BE READ FROM URBPARM.TBL

This makes me confused about whether URBPARM.TBL was actually read. Why is 'DEFAULT URBAN MORPHOLOGY' being used? Shouldn't all settings be read from URBPARM.TBL?


Thank you for your answer.

Not sure if/when it is read, but there is a very simple test to figure it out. Delete it and rerun. If you get the same results, it is not being read. Otherwise, it is.

Yes, you're right. Thank you for your advice and I'll try it later.
