Do you suppose corona cares whether the air molecules themselves are
charged or whether the unbalanced charge is held on these highly
electrified dust particles?

Corona requires an ionized path through the air with
a sustained current of 100 uA per cm^2. What you are
calling corona is not corona. If a charged particle
is not in the act of discharging, by definition it
cannot be corona. On a clear dusty day, where is the
ionized glowing path through the air that necessarily
accompanies corona?

What W8JI has previously been describing is the electric
fairweather field, not corona. Please see:
