The site location should be at the mark shown -- or very close. Clicking within the map area (or you can drag the 'DW2649' 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. Show location history.

There are no photographs of the station. If you are the site operator and have pictures of this location, then please email them to d2649@photo.gladstonefamily.net.

APRS Location

APRS Location recorded at 2021-Jul-24 00:17 UTC
Latitude: 41° 5' 49" N (deg min sec), 41.0970° (decimal), 4105.82N (LORAN)
Longitude: 112° 3' 11" W (deg min sec), -112.0530° (decimal), 11203.18W (LORAN)

The location reported in the weather reports (via APRS) is significantly different to the registered location above. In particular, the difference is about 123.0 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.

Data Status

Over the last 28 days, no data was seen on the following dates: 2021-06-26 to 2021-07-18.

Data is being seen at findu.com, but this site is not currently marked as active. To fix this, send email to CWOP-Support and ask her to activate your site.

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.

A recently received weather report from this station was

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.

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 23 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.

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!

Location Formats

The location is shown in three different formats. Each of these is used in some software, and is shown on some websites.
