There's a decent difference between sheltered and unsheltered from my experiences. 6-8F is probably on the very extreme side...most of the ones I've seen run a good 3-5F too cold on rad nights. Like you said, it depends on the radiating properties of the sensor. Some of them are like perfect mini blackbodies. On 10/21/2014 at 1:20 AM, HoarfrostHubb said: I still don't get how something like a Stevenson shelter prevents it from radiating less than an unsheltered thermo It's all about the net radiation. Inside of the shelter the sensor is losing heat via emitting longwave infrared, but it gets re-radiated inside of the shelter. When you add fan aspiration you're continually refreshing the sensor chamber with the "new" current 2m temperature. A sensor exposed to clear space at night has little radiation being reemitted back to it. The net is essentially just one way...a loss of longwave infrared out to space. It's essentially the same thing that the sfc of the ground experiences on a clear night. Keep in mind that the ground skin temp can be a solid 3-5F+ colder than 2m on a rad night. It's why we can get frosts despite 2m temps of 36-37F. Link to comment Share on other sites More sharing options...
HoarfrostHubb Posted October 21, 2014 Share Posted October 21, 2014 Thanks, Brian. Would the thermometer also eventually reach an end temp of the dew point? Link to comment Share on other sites More sharing options...

Sure, it could...just like the ground can. You'd get dew/frost formation on it. Link to comment Share on other sites More sharing options...

That's been trending higher and thus less of a torch here compared to previous runs, but I think the idea of a milder start seems for real. Not that it means anything of course, but there are a few that will get antsy. Link to comment Share on other sites More sharing options...

Obviously storms can "feel" that warm water and usually end up tickling towards it. A good lesson in Atmospheric dynamics. Link to comment Share on other sites More sharing options...
