I'm not sure why the "official" temperatures are taken there like you said.
Airports have been local official wx measurements as far back as I know. The equipment is meant to be checked for accuracy one or twice a year and supposedly top of the line. Decades ago, airports were much smaller than what they are now (props vs jets, just for starters..), so perhaps the surrounding terrain wasn't as influential. Needless to say, AWOS's and ASOS's ain't cheap, nor is the upkeep and ensuring proper security, so siting them away from airports isn't cost-effective. My 2 cents.

Hi!

I see a little clearer ...
The transmitted AD value "soilad1..8" is NOT the calibration value but the actually measured raw value. This raw value is now also transmitted.

But:
I still do not understand the sense of transmitting this raw value!
What do I do with it?
If I have calibrated the sensor so that it transmits a correct percentage value of the soil moisture - why do I still need the actual measured value?
Maybe you can explain the added benefit?

In Ecowitt's own forum there was a post here about calibrating the WH51 with reference to the sensor's manual. BTW: there is a newer version of the WH51 manual.
Maybe you can develop an idea from that?

Some very cool shots.

Yes they are (meaning they are calculated by the gateway), or at least to Ecowitt.net, I did not try custom , but I can't imagine in would be different.
Now this is from a GW1000 , which is what I use for my soil moisture sensors.

I also forgot those sensors have 2 calibration points for this gateway, 0% AD, and 100% AD, stock values being 70 and 500.

So that raises further questions. As I do not have a WN1980 I have no idea how those are handled with that unit.

But are they only throwing out one calibration value Oliver?,  because that would make even less sense

So this is the only inside photo of the 076b Iíve been able to find. Itís from the USCRN website. Iíve rode out to a nearby USCRN site nearby and Iíve been able to see the intake. As you describe, it looks like a multiplate assembly at the intake with two shields with offsetting holes to block incoming light. The two outer tubes for scrubbing make sense, but what I donít quite understand is how the air flows into the inner tube with the actual sensor. From the photo it almost looks like there is another additional plate at the bottom of the inner tube, but itís hard to tell. So the air flows through the 9 holes of the bottom plate, through a second plate with holes presumably at the center of the plate and then there is potentially a third plate just smaller than the diameter of the inner tube at the inner tube intake? Do you happen to recall?

A few of my lightning photos over the last 20 years or so. I'm kind of burned out on photography after doing it professionally for half my life, so you probably won't see much more in the form of pictures from me.  :grin:

My first good lightning shot. Probably about a 30-second shutter speed.

Video screen grab.

One of the most difficult ones to get since it was daytime and I couldn't just do a long shutter.

Hi!

I had asked Ecowitt again about the soilad values and the, in my opinion, completely unnecessary permanent dispatch via custom server.
Here is the answer from Ecowitt:
Quote
The custom mode is calculated on gateway side, if people need to use the custom mode, these raw ad value is needed. So we included them in the package.

The calibration values are important - no question.
But I gain nothing at all by receiving the set calibration values with each transmission - the calibrated soil moisture values already arrive!

Ecowittís answer would make sense if the sent data would contain the uncalibrated values, and the correct value is calculated by the receiving party. But this is not the case, is it?

That's fair. I'm not sure why the "official" temperatures are taken there like you said. It isn't indicative of the general environment rather the near runway conditions.

The sites are standardized but the siting is by no means grounds for a climate station.

Thanks for your time and effort to communicate with Ecowitt on this, Oliver.  I agree with you on this and wanting clean, efficient data.

It sounds as if the soil moisture values are not adjusted when sent via the custom server option.  Then they are sending the adjustment/calibration values plus the original values so it's up to the software that receives the custom server data to calculate the final values.

I don't think any other data is sent that way and I don't understand why the calibration wouldn't be applied first and then the resulting values are sent.
