The site location should be at the mark shown -- or very close. Clicking within the map area (or you can drag the 'GW5331' 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.
NOTE: The Registered Location is the location that the station owner provided when they signed up with CWOP.
Latitude: dummy (deg min sec), dummy (decimal), dummy (LORAN)
Longitude: dummy (deg min sec), dummy (decimal), dummy (LORAN)
Estimated elevation is dummy metres (dummy feet) from dummy.
Location is dummy (reverse geocoded).

There are no photographs of the station. If you are the site operator and have pictures of this location, then please email them to g5331@photo.gladstonefamily.net.
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:
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.

The location reported in the weather reports (via APRS) is significantly different to the registered location above. In particular, the difference is about 20.1 miles. If you have changed your location (or software) since the time above, then this can be a false alarm. Check the location currently being reported at findu.com.
Please check which location is correct. If the registered location is incorrect, then you can correct it by dragging the marker above and using the 'send the updated information link'. If the APRS location is incorrect, then you must enter the correct coordinates into your software which generates the weather report (APRS) messages. Note that the various different types of software take the location in different formats, so be sure to use the correct format when entering the latitude and longitude.
Recent observations from this weather station can be downloaded as a CSV file suitable for importing into various spreadsheet programs: last 7 days, last 14 days, last 28 days, last 56 days. This data can also be linked directly from Excel using a Web Query. The main link goes to the page with the data on it, and the IQY link is the Web Query that will access it: last 7 days (IQY: last 7 days), last 14 days (IQY: last 14 days), last 28 days (IQY: last 28 days), last 56 days (IQY: last 56 days).
All the means and standard deviations shown below are from the last 28 days. Change analysis period to Last 3 days Last 7 days
The analysis is performed by MADIS. This web page just provides visualization of the data that MADIS produces. There are a number of very knowledgeable people who participate on the WXQC Mailing List who do understand exactly how MADIS works and can resolve issues when the analysis seems to be broken. However, in most cases, the station readings are at fault, or the software that is transmitting the data to CWOP. Please check those paths first.
You can also see how this station compares with other stations.
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.

Latest daily graph:
These values are within range, so your sensor is probably calibrated correctly.
NOTE: If the error above is POSITIVE, then it means that the analysis temperature is HIGHER than the reported temperature. This means that your sensor is reading COLDER than expected. |

Latest daily graph:
Not enough data has been received to perform a day / night analysis to check for various types of shielding problems. Please wait a few days, and then try again.

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 20 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.
