[TOC] The pressure presented on our web pages is adjusted to sea level. This is common practice and makes it possible to compare data between stations. To adjust back to absolute atmospheric pressure, multiply the sea level pressure by: =((288-0.0065*ElevFeet/3.28)/288)^5.256 where ElevFeet is the elevation in feet. You can see that ElevFeet/3.28 is the elevation in meters. The sensor is usually accurate to within 3 mb. If you need more accuracy than this, you’ll have to get a mercury barometer and take your own measurements. You can get data from our Site 300 barometer from our web site. Also, you can get barometric data from the Livermore Airport (KLVK), Oakland (KOAK), and Stockton (KSCK) here. You might have to start at the University of Wyoming home page and click on Weather and Surface Observations.
