2 WRF-ARW v3.4 coupled with SSiB v3.0 land-surface model
5 The SSiB v3.0 is a land-surface model with a multi-layer snow scheme.
10 To run WRF-ARW with SSIB v3.0, set sf_surface_physics to 8
12 Currently, the SSIB will only work with the following options:
13 1) SW and LW radiation schemes: 1 or 3
14 2) Surface layer schemes: 1
16 4) Eta levels: the first two levels must be 1.0 and 0.982
17 For example, for a e_vert=28 domain, eta_levels may be set to:
18 eta_levels = 1.000, 0.982, 0.973, 0.964, 0.946,
19 0.922, 0.894, 0.860, 0.817, 0.766,
20 0.707, 0.644, 0.576, 0.507, 0.444,
21 0.380, 0.324, 0.273, 0.228, 0.188,
22 0.152, 0.121, 0.093, 0.069, 0.048,
24 5) num_soil_layers = 3
29 By default, SSiB will work with the USGS land-use maps, however,
30 for better results, we suggest that you use the SSiB land-use (vegetation) maps.
31 This can be done by prefixing the variable geog_data_res with string "ssib+"
33 For instance, to use SSiB 10-minute resolution land-use map:
34 geog_data_res = 'ssib+10m',
36 Make sure to set the correct path for the SSIB land-use maps
37 in the GEOGRID.TBL file
39 abs_path= ssib:your_path/vegtype_10m/
