How do you know those instruments in the photo are measuring temperature?
- giantg2 3y agoI'd assume (maybe wrongly) proper air measurement would require some adjustment for things like density based on altitude, temperature, etc so there's a standard to compare it to.
- stephen_g 3y agoThe cylindrical unit half way up the pole and to the right with the louvres is a solar radiation shield that would be typical for containing a thermometer and possibly a humidity sensor - the louvres let the air through without letting direct sunlight hit the thermometer and throw off its reading. But I’m sure they aren’t using it as a calibrated value (obviously they would have guidelines for placement and would know this doesn’t meet them), it’s probably just being used as an indicative reading.
