frustrate UCM

Postby colopolo70 » Mon Jun 08, 2009 10:27 pm

Dear All,

I am testing the effects of UCM option on Tokyo area with 3 nested domains for 1 month.

1. When I quickly check the results of TC_URB, TG_URB, and TB_URB, The value did not change with time.
So, I frustrate the result of UCM. I thought that if UCM option would be used, UCM variables (such as above mentioned vaiables or UCM variables) should be changed with time.

2. I am interesting heat conductivity of wall, roof, and road (AKSR, AKSB, AKSG). but I don't know where I can
find time series of these values.

Please give me any tips and ideas about using UCM model.

The below is my physics option
------
&physics
mp_physics = 6, 6, 6,
ra_lw_physics = 1, 1, 1,
ra_sw_physics = 1, 1, 1,
radt = 9, 1, 1,
sf_sfclay_physics = 1, 1, 1,
sf_surface_physics = 2, 2, 2,
sf_urban_physics = 0, 2, 2,
bl_pbl_physics = 8, 8, 8,

bldt = 0, 0, 0,
cu_physics = 1, 1, 0,
cudt = 5, 5, 5,
isfflx = 1,
ifsnow = 1,
icloud = 0,
surface_input_source = 1,
num_soil_layers = 4,

mp_zero_out = 0,
maxiens = 1,
maxens = 3,
maxens2 = 3,
maxens3 = 16,
ensdim = 144,
slope_rad = 0,
topo_shading = 0,
sst_update = 1,

Had you set up these variables in the Registry.EM file?
I'm trying to accomplish an ucm run, but I'm in early steps. I've read about registering variables somewhere.

Hello everyone,
I have downloaded the NLCD 1990 data from earthexplorer.org for Florida. I have been successful in obtaining urban roof skin temperature and canopy temperature, however the urban wind parameter is appearing to be zero. Any suggestions on how to obtain the urban wind parameter ?
I have initialized it as "rhd" in registry.EM_common
