It confirms. With all the air that he sucks always arrives much earlier than others both uphill and downhill. I think, as Toby said, the sht35 naked inside it will not last long but in this first month of use I am personally very satisfied

I won't get an Apogee but I do intend on putting a much stronger fan inside the Davis FARS sometime in 2025, I wonder whether that'll make it look similar to the Apogee.

I hereby inform you that, and I apologize on behalf of the Company, from now until the end of the Christmas and New Year holidays, shipments will be suspended.

I am of course always available for any need and, in the case of orders, to manage them in the appropriate timeframes that will be not very quick, in agreement with Siap+Micros I will evaluate possible emergency.

Thank you all

Hello,
I have searched everywhere in internet for a shop, dealer or so who sells this shield, but found nothing.
What distribution channel do they use? I have looked at their official website but they don’t have a BTC shop, as far as I saw.

Thanks a lot.
Happy holidays.

My report from yesterday! Since day 24 the Metspec Rad 14 has become my reference! After a year of careful evaluation the Rad is the screen with the best performance in my observation point! Then since December 20th the Cometeo f8004 screen has been tested on my site which has taken the place of the Barani Meteoshield Fars! Tested for years now in the normal version and in the Fars one! Both excellent screens but on my site the Rad 14 has always proven to be the best performing! I renew my wish to all the users of the Forum for a peaceful Christmas!

The station with the screens in use! I remember that my station is of the urban type! And placed 2.5 meters from the roof on the terrace of a building! It is located in the south/west quadrant of the city of Rome ... 200 MT from the Tiber River and 20 km from the Tyrrhenian Sea.

Hello,
yes I confirm that there is no e-shop or official direct resellers, Siap+Micros does not sell directly to private individuals.

However, there is an agreement, which concerns the MeteoNetwork association, I am the person in charge of selecting direct requests from private individuals and evaluating the possibility of a direct supply.

If you are therefore interested you can write to me, perhaps attaching a brief description of your installation and specifying the type of sensor you would like to use.

Sunny and windy days continue. Systems during the day very aligned.

After having pretty much no sun for weeks (5.2 h since the 6th of Dec), today was finally sunny and immediately gave interesting results. My anemometer returned no data for some time as the cups froze solid, but there was some wind around sunrise (around 5 km/h from what I can tell from official stations and interpolation). There was a period from 11:00 to 12:30 where the SC went as much as 0.8C cooler than the Davis and this was with low/moderate wind and low sun, so completely the opposite of what you'd expect, as you'd expect the passive shield to be warmer than the active one in such a scenario. I think the main reason for this is that there was ice on the plates of the SC and the ice was in the process of melting, something that requires energy, and I suspect the melting process extracted that energy from the incoming air into the shield. Before and after the melting process, the shields ran basically the same, despite the continuous low/moderate wind (5-10 km/h at 5 m height) and low angle winter sunshine. Imo, this is some evidence that the low sun angle effect does not occur on the SC with wind speeds of 5-10 km/h. As for the strange cool period on the SC, this shows the advantage the Davis design has with drawing in air from below, as it can't be influenced from water/ice/heat/whatever from the plates.

Here's the graphs with the difference between the shield and the actual temps. You can see that the SC (orange line) lagged behind right as the temperature was around 0C, which indicates that the melting process was likely influencing things here and stopping the rising trend via extracting heat needed for the phase change.

Thanks for the contribution and the wonderful images ;)

I agree with your conclusions, overcooling due to rain or ice is absolutely obvious and affects most passive screens in a more or less similar way.

Anything that lowers the surface temperature of the components of a SRS to a level lower than that of the air can affects the sensor data, and this is inevitable.

Report yesterday. Interesting behavior in the morning, when temperatures and radiation began to rise after the morning frosts
During the day all screens aligned with negligible average deviations

Happy New Year to all!

Report from yesterday.
I added in the first chart and report a test on Apogee with inside probe ds18b20 in VN34 Ecowitt.
The first data are very comforting, from my point of view. End OT.

Very good SC and all other systems

The fact you’re getting more frosts than me at 51N in Belgium just shows how horrific the climate here is. Going back on topic, what is that undercooling of the Apogee in the morning there? Looks very significant.

...about the minimum take into account that I installed weather stations on a farmland in an extra-urban area. At home, in the city, it’s different.
About the peak of the Apogee, I think it may be because we were up in radiation, without wind with a decent cold layer on the ground that Apogee kept breathing while the other screens, I guess, start warming the air inside. These are just my guesses. Already today, the situation is different "thanks" to a slight blight of wind during the same period. Also look at the distance between Pro3 and Rad14

There’s not been much frost here in the countryside or the city, so from that perspective it hasn’t mattered a whole lot. Just a very poor climate here.

Report yesterday. Changes in ventilation and drop in temperatures during the night. Rain during the day, where good alignment between systems could be observed

Deviations of yesterday’s day of passive screens only. At about 13:30 fog returned (also present during the night) and the temperature dropped. Reaction of the systems in the graph.

Just thought I'd post another winter picture of the SmartCellino in action. Thanks to everyone for posting their comparisons!
The photo was taken today at 14:00 and the temperature at that time was -17,3°C.

Tomorrow evening a weakened snow "storm" will hit my location after it has moved over the southern and southeastern part of Norway.
The expected snow accumulation here is 25-30 cm in 24h with wind gusts up to 14 m/s.

Very jealous! That same storm is currently giving me temps of 11-12C, after some snow fell overnight. Enjoy! Maybe a good idea to clean the snow off the shield?
