I have an Air/Sky myself, but several of my friends from college (all of us are meteorologists) want to purchase WeatherFlow units, however they want actual in-situ measurements of temperature. With the Tempest being placed in potentially full sun (with no fan) that doesn’t seem possible. Yes we rea…

That is a downside of the one-sensor-suite architecture for sure. Seems to me that you want a calibrated LAN-only instrument in a Stevenson Screen if you want really accurate readings that aren’t “helped” by the vendor changing the tunings or doing magic math on the readings. I’d suggest WF might …

WeatherFlow will come out with a commercial lite weather station in the future. How soon? That I don’t know.

These are good ideas that I’ve also thought about. I guess it’s unfortunate because I placed by Air in full shade and get great readings, but now that’s no longer an option. And a $1,000+ Davis really isn’t in the cards for us on a budget :slight_smile:

I have an Air/Sky combo with the add-on solar for sale. I keep thinking about putting it on eBay, but I will gladly sell it here. PM me or email gmm@ t i k c u f dot com

Yup. Maybe you can pick up a used station cheaply. Perhaps do a ‘looking to buy’ thread with exactly what you want

“black box math” isn’t the same as physics. Do you really care how the temperature is measured? as long as it is correct, it should be fine. Because the physics model also needs data from solar radiation sensor and wind sensor, it might be slightly less accurate (in case errors in those sensor read…

Call it what you will, but unless the equations and algorithms are spelled out, a scientist sees it as “black box math”. There are hundreds of meteorological equations in existence, but if they are not explained, any scientist would be skeptical. At the same time, WeatherFlow is a public company tha…

there is a difference between physics and black box math. Both can be very scientific. I wouldn’t be surprised, if they made a thermal model of the unit and applied the relationship between solar radiation and the measured temperature vs the real temperature. Then do some experiments to get some cal…

btw, never buy two weather stations, one of them will always be “wrong” :slight_smile: (saves you some money too)

I did have many ds18b20 and dht22 sensors to compare my Air/Tempest units with, as well as a Davis VP2 and Ecowitt units. So I did that experiment. The Tempest was slow to warm up, ran hot once it stabilized, and was slow to cool down as the sun set. That tells me bad thermal design of the case. …

Still Able to Purchase an Air/Sky Unit?

Unless WF have changed the algorithm since last summer (perfectly possible!), the maximum temperature correction they make is 1.5 deg F, so I don’t think the difference you are seeing is due to the algorithmic correction. It is probably more related to the different thermal properties of the two devices.
