The site location should be at the mark shown -- or very close. Clicking within the map area (or you can drag the 'L34BX' 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.

Can you help with location quality? Please indicate if the marker on the map points at the weather instrument cluster:

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. Show location history.

There are no photographs of the station. If you have pictures of this location, then please email them to l34bx@photo.gladstonefamily.net.

Picture Submission

There are two ways to submit pictures. If you are a flickr user, then see the flickr section below. Otherwise you can simply email the pictures as follows:

Email the pictures to l34bx@photo.gladstonefamily.net.
If you use a smartphone that embeds the GPS coordinates in the pictures, then you can send any picture of a weather station to gps@photo.gladstonefamily.net and it will be associated with the correct station automatically.

Flickr Upload

Uploading picktures to flickr.com is easy. If you do not have a free flickr account, then you need to create one. Just go to flickr and click the 'Create your account' button. You can use a google account if you have one.

Once logged in, click on 'Upload Photos & Video'. Next click on 'Choose Photos and Videos', and walk through the process to upload your pictures. They will automatically be resized appropriately.

After the upload is complete, it will ask you to add titles, tags and descriptions. The key step is to add tags as follows:

wxtagged -- this indicates that this picture is of a weather station or surrounding area
wx:id=l34bx -- this indicates the site of which this is a picture
wxstation -- add this tag if the picture includes the weather station.

If you had to create your account, then you must upload at least five pictures. It will also take longer for your pictures to appear (a week or so). Otherwise, the pictures should appear after 24-48 hours.

You can try to find photographs from the area surrounding the site marker by clicking on Find nearby photographs. (There are some) (There are none) (There may be some) (Automatically loaded if any)

Latest daily graph:

There is a significant mean error in your barometer readings. You may need to calibrate your barometer. Since your readings are low, it is possible that your software is not adjusting the reading for elevation, or that your station altitude has been entered incorrectly into your software.

Neighboring Stations

This is a list of stations that are close to this station. Note that this is not the list of stations that are used in the data analysis. That list of stations is known only to MADIS. You can see all the stations at MADIS Data Display. Your station should be in the middle of the display. If you think that the analysis is incorrect, then maybe one of the close stations has failed.

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 24 days out of 28), the offsets below may not be accurate.

Quality Control Notes

This page reports on the quality control checks performed by MADIS. The green check mark and red cross are chosen based on the average performance during the analysis period (which is selectable above). The red cross can appear even if MADIS reports that all observations pass the MADIS QC checks.

The 'MADIS rating' reports on the percentage of observations that pass the MADIS checks. You should aim for two thumbs up!
