Re: [weewx-user] Re: altitude for barometer calibration

If you are comparing your external sensors to your console's barometer keep in mind that the offset does not mean the sensor is out-of-spec. An absolute offset is not a specification. It is just the sensor correction offset so that all your barometers read the same absolute pressure. I am assum

thanks for the comments. I will be digesting all of the replies and CWOP data and coming up with a cal plan. "gszla...@gmail.com" writes: > For a Davis VP2, SLP is already calculated for you in the console so all > you need is the elevation of your sensor. Hwever you still need to check if >

Looks like you've got the elevation for your location nailed down if you've gotten it down to 10cm. For us ordinary folks we have to rely on topo maps or google earth ( or similar map reference tools) to get down to 1 meter accuacy. Not all countries have gone digital for surveys quite yet. Her

Also doesn't it vary with temperature? The formula I use is at Conversion to sea-level pressure Calculator - High accuracy calculation (casio.com) (which is also used in a number of other sites). Susan On Sunday, 29 May 2022 at 2:41:27 am UTC+

Greg - does https://www.usna.edu/Users/oceano/pguth/md_help/html/vert_datum.htm help any ? There are some links at the bottom of the article to NOAA info as well... -- You received this message because you are subscribed to the Google Groups "weewx-user" group. To unsubscribe from this group
