running idealized Thompson aerosol-aware simulations

[frankr]

Hi,

I've been running idealised convection WRF 4.2.2 simulations in derecho with
Thompson mp=8 microphysics and am now trying to use the aerosol aware scheme
(mp=28) with mp_physics=28, use_aero_icbc=.false.
The problem is it won't run and the output error

FATAL CALLED FROM FILE: <stdin> LINE: 4506
module_mp_thompson: error opening CCN_ACTIVATE.BIN on unit 20

Can anyone advise me what to do?

thanks

frank

I fixed this by copying CCN_ACTIVATE.BIN from /run

ok now.
