OK, thanks. A good "offline" comparison of your sunshine sensor with the formula will be difficult, since with your archive data the fomula will produce only one estimation for a 5 min period, based of the archive radiation measurement , which is the mean radiation measured over of archive period . When used "online", as an installed weewx extension, the evaluation is done on the basis of the instantaneous radiation LOOP data, and is updated as soon as a new radiation value is sent by the Davis radiation sensor (about every 50 seconds).
