The site location should be at the mark shown -- or very close. Clicking within the map area (or you can drag the 'FRLU1' 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 2 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: 2024-09-19 to 2024-10-05, 2024-10-07, 2024-10-09 to 2024-10-11, 2024-10-14.

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

By default, the longer analysis periods display graphs that show the long term performance of this station. The graphs show the mean error over time, and include error bars which are one standard deviation long. This provides an easy way to see if there are any underlying trends in the data. Note that a 'step' in your data does not (necessarily) mean that something happened to your station. It could mean that another station came online in the local area, and they are changing the analysis.

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.

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