« Last post by CW7491 on Today at 08:22:57 PM »Yeah, that's just not right. To be honest, it's not that surprising considering the NWS is using equipment manufactured by a company that went defunct nearly 15 years ago. It comes down to cost I assume. Lots more user friendly technology available now with the ability for better siting. The issues with the current MMTS system have been documented. Although the radiation shield seems to work well. Even Davis published a study in comparison around 2007 and ran into problems https://ams.confex.com/ams/87ANNUAL/techprogram/paper_118190.htm
I was also surprised they accepted this COOP MMTS tying of the Utah state temperature record on siting alone ...

ASOS isn't immune either though as I posted elsewhere a really interesting video from NWS Lexington KY documenting the extremely lax tolerances. At least a fix there is in the works ...

« Last post by CW2274 on Today at 07:53:51 PM »I guess the point I was making (or trying to make) is the term “sea level pressure” applies to both Altimeter setting and SLP. SLP is called sea level pressure (Aviation Weather Center) - that's what S-L-P stands for, but Altimeter is also “sea level pressure.” In other words, both are converted down to sea level.I get what's trying to be conveyed. Problem is, they're not the same. I think a lack of further explanation here (by whomever) has some people thinking that they actually are. For instance, my altimeter right now 29.82, but my SLP is 29.62. Quite the difference.
I think the aviation industry got it right; QNH = QNH and QFF = QFF. No confusion there and no head scratching about sea level pressure, barometric pressure, etc, etc.
Aviation had to get it right. It's used for vertical separation from other aircraft and terrain below 18,000' (FL180).

Thank you! I thought I confirmed it was still 008 yesterday, but maybe I looked in wrong place.
Can confirm that fixes the error!
Thank you again!

If you are new to personal weather stations, it will take a while to just “know” the difference. It's all in the details...

I can't comment much on the latest Davis console as I don't own any of their equipment. However, I did see that 6313 console thread and was a bit surprised. No SLP, just Altimeter is what I understood. An interesting design choice for a weather console.

Davis Instruments Weather Stations / Re: console 6313 restart stuck
« Last post by thomas on Today at 07:21:12 PM »I had a console freeze up after an update. Never could get it to work and Davis sent me a new one. It was very difficult trying to reach someone at Davis. After many call attempts I reached a time when I was second in line. It still took 20 minutes to reach a live person. Yes, since the sale the customer service has fallen way off.

« Last post by CW2274 on Today at 06:09:43 PM »Some METAR reports are not especially helpful for discriminating between the two different sea level pressures, either. Sea level pressure in a decoded METAR report would indicate SLP as “SLP (sea level pressure).” But for Altimeter (setting), there is no equivalent descriptor and no indication that it is, equally, a sea level pressure just like SLP.Unless I'm missing what you're getting at, the altimeter in an encoded METAR is notated by an "A" followed by the setting, minus the decimal in inHg, but I know you must know that. As far as the equivalent descriptor, my take is that the people who primarily use this information have been educated on the similarities and differences of the two, and most novices don't care, unless they're "us".
It seems some (most?) weather station manufacturers are avoiding using the standard meteorological terms like station pressure, Altimeter (setting) or SLP.
Like I said in another post, things continue to be dumbed down for the buyer, hence the lack of description. At least the VP2 and Vue console tell you what you're choosing, and that's the way it should be, even if there is no choice. Which is it? Temp is temp, humidity is humidly, but the pressure is not necessarily the pressure, if you get my drift. Exactly why the type of reduction (or none) being used should be included, always. That irked me about the 6313, they tell you nothing.

Got the HP1553 and the GW2000. Data reporting via the GW2000 to the regular weather sites and then to a custom python script that pulls the data into my local database 😎
