Error simulating lightning NOx using WRF-Chem.

[Manas Ranjan Mohanty]

Hi everyone, 

I am trying to run a test case with WRF-Chem by switching on the lightning NOx option. But I am getting an error which states "lightning_init: Selected lightning option requires microphysics and do_radar_ref=1". Do we need to set some specific microphysics options for computing the lightning NOx? 

I am simulating 2 domains at 20km and 4km. I have used the lightning options as 11 and 2 respectively. 

I have attached the namelist file for reference.

Hi,

It looks like you just need to add to the namelist in physics:  do_radar_ref = 1 

It appears that the default is 0 for this namelist variable.
