To make this same standardization and ensure consistent readings enter your elevation in this screen." "Meteorologists standardize barometric pressure data to sea level so that surface readings are comparable, whether they're taken on a mountainside or by the sea. I would guess that Davis is supposed to adjust the barometric pressure in the console? Right in my Davis manual I find: I think there is a good reason though, the Davis stations do ask for your elevation. However, this comment is not to be found for Davis stations. That would suggest that Stu is correcting the barometric pressure for some stations and I would guess that is to adjust it for sea level. "Please note, WeatherCat uses your altitude to calculate relative barometric pressure with this station ? please be sure your altitude is correctly set in WeatherCat?s preferences." However, for a number of station models there is the cryptic comment: I checked the WeatherCat manual and there absolutely nothing you can set with respect to barometric pressure. Good luck convincing them your data is good. I'll check and see if the pressures change at the airport. ![]() Nope, that probably accounts for my not getting that nasty email. I'm not sure I even forward my info to AWEKAS. ![]() There is no "SLP" reported in the 'normal' Wx report, nor would I expect it! My station is reporting 29.88 on the hour, I suspect the newest NWS and METAR reports will show up any minute. ![]() That agrees with the METAR of almost exactly the same time. The "current" NWS weather report for Memphis shows 29.93 in/Hg as of 5:54 local (nearly an hour old. I think most crews will be using charts as a back up, of course. For airlines, most of that is already done by company computer, often with the required data input from the METAR data, or by the crew with Automatic Terminal Information System, and a laptop/tablet. But that is really only used, as far as I know, for computing aircraft performance. I get the pressure converted to sea level in my METAR reports.
