Registered Location

Latitude: 77° 57' 0" S (deg min sec), -77.9500° (decimal), 7757.00S (LORAN)
Longitude: 166° 30' 0" E (deg min sec), 166.5000° (decimal), 16630.00E (LORAN)
Elevation: 10 metres (33 feet)
Location: US Navy Automated (USA), -, Antarctica (the territory South of 60 deg S)

The elevation does not correspond with the estimated elevation (-9999 metres (-32805 feet) -- source Geonames) at that point. Either the location or the elevation (or both) are almost certain to be incorrect. 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 '89667' 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 metres. Note that handheld GPS receivers do not provide readings of elevation accurate to better than 10-20 metres (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 3 data sources. 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. Show location history.

Data Status

Over the last 28 days, no data was seen on the following dates: 2023-08-28 to 2023-09-07, 2023-09-09 to 2023-09-22.

All the means and standard deviations shown below are from the last 28 days. Change analysis period to Last 3 days Last 7 days Last 14 days Last 8 weeks Last 13 weeks Last 26 weeks Last 39 weeks Last 52 weeks

The inconsistency noted above in your location information means that the analyzed readings for your location may be incorrect. For example, if your location is incorrect, then the analysis values will be for a location other than your station. This will give different analysis results, probably leading to errors being shown below. If the elevation is incorrect, then the comparison of temperature readings will be in error.

Neighboring Stations

This is a list of stations that are close to this station. You can look at those for comparison purposes. The average difference between your station and each station below is listed as well. This may allow you to detect local stations which are erroneous. You can also use these numbers to adjust your instruments -- especially if a number of ASOS stations have similar differences to your station. Also, try increasing the analysis period to more than the default 28 days. The difference is only given if both stations report reasonably often during each day. Some stations only report every 6 hours, and this makes the average of less interest. In this case, the average is not displayed. The values reported are the differences between this station and the neighboring station. I.e. if the difference is positive, then this station is reading higher than the neighboring station. Since this station has not been reporting continuously during the analysis period (it missed 25 days out of 28), the offsets below may not be accurate.

The sites marked above thus did not report continuously during the analysis period, so the offsets may (probably will) not be accurate.
