Hi,
I am trying to run WRF simulation by using ERA-5 model level to simulate the upper stratosphere and lower mesosphere.
I download the ERA-5 model data from CDS, and I successfully run ungrib, metgrid, and real.
However, my simulation created nan values after a few steps and crashed. Note that the model top is set to 1 hPa.
Could you give me some suggestions?
I am using WRF Model Version 4.7.1 and WPS 4.6.0.
I downloaded values as follows:
3D data-> geopotential, T, u, V, q, lnsp,
Surface data-> mean_sea_level_pressure, skin_temperature, 2m_temperature, 10m_u_component_of_wind, 10m_v_component_of_wind, 2m_dewpoint_temperature, geopotential, land_sea_mask, sea_surface_temperature, sea_ice_cover, snow_depth, soil_temperature_level_1, soil_temperature_level_2, soil_temperature_level_3, soil_temperature_level_4, volumetric_soil_water_layer_1, volumetric_soil_water_layer_2, volumetric_soil_water_layer_3, volumetric_soil_water_layer_4, snow_density, surface_pressure
My vtable is as follows:
