Good question, but my impression is that it is really difficult to measure humidity above 95%. I more or less have the impression that fog happens when temp/dewpoint are about the same and the temperature falls. I think you need a fog sensor that actually measures impaired light transmission. Surely there is a norm for measuring that already. I need one too, right after I build a seismograph. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
