I appreciated the added detail of using barometric pressure to calibrate the RH%. One issue that wasn't covered on any other instructional video for the sling psychrometer for fire weather calculations is, if it is sunny out, spin the psychrometer using our own shadow to keep it out of direct sunlight. Thanks again!

Im in IT. I came here because I got sent down to the basement where the building engineers sit and was trying to figure out what this thing was.
