@dsj I’m really struggling to understand what’s going on here. As you can see from the chart, at 7:30 my pressure was 30.346, virtually identical to my Davis VP2 and surrounding, trusted stations (including NWS/FAA sites nearby). But then, all of a sudden, it was off to the races as the pressure increased to 30.54 for absolutely no reason. Why would the CL take over in a situation where every trusted station is reporting essentially the same 30.34-30.35 readings? What would be the purpose of increasing pressure to 30.54 which no station in my area is even close to…even ones I know are whacky.
At some point (my station has been up for 2 weeks now) doesn’t the CL process say, “Yup, that reading is essentially correct as I can see from trusted sources (my Davis is supposed to be one of them) and I’ll leave it alone”? There’s got to be a gap in my understanding of what’s going on here. BTW, my new Air behaves essentially the same way except for more false lightning strikes than my first Air. However, in general, my original Air seems to be doing somewhat better overall.
Dave, can you ‘splain’ this weird barometric pressure behavior and when, if ever, does this settle down?
