The elevation does not correspond with the estimated elevation (0 meters (0 feet) -- source NED Alaska 2 arc second (15 minute) elevation data) at that point. It seems probable that the elevation was entered as feet rather than as meters. Please use the 'send the updated information' link below to update the location or elevation.

The site coordinates appear to be of low precision, and the station may be anywhere within the marked area. Clicking within the map area (or you can drag the 'PABX' marker) will display the latitude/longitude of that point.

If the displayed location (or elevation) of the weather observing location is incorrect, please drag the marker to the right location (or click in the right location), and then send the updated information. Please note that we are trying to spot either the Stevenson Screen (or equivalent) or the location where the barometric readings are taken.

The best way to get elevation is to consult a topographic map. Make sure that you know whether the contours are marked in feet or meters. Note that handheld GPS receivers do not provide readings of elevation accurate to better than 10-20 meters (technical discussion). If you do not have access to a topographic map, then a GPS receiver is acceptable, but make sure that it is operating in 3D mode and let it average the position for at least five minutes.

For more information on reading maps, please see the Topo Map Reading Guide -- in particular it discusses how to read contours.

The location information for this site was gathered from 1 data source. The source which most closely matches the consensus is chosen. Many of these sources only report the location to the nearest minute (or hundredth of degree). This can lead to the marker being placed noticeably incorrectly. Please see Discussion of Location Errors for more information.

There are no photographs of the station. If you have pictures of this location, then please upload them to Flickr (detailed instructions) and add the two tags 'wxtagged' and 'wx:metar=pabx'. If the picture is of the weather station itself, then please also add the 'wx:station' tag as well. Please geotag your images, and those coordinates may be used in the estimation of the location of this site.
