I've been wondering about this for a while, do you have a reference? Do you know how humidity affects transmission? Pre-pandemic I used to go indoor bouldering where there tends to be a lot of chalk in the air and I was curious how that affects transmission. Couldn't decide if the dryer air meant less transmission, or the larger particles meant more maybe. Couldn't find anything about it.
