The site location should be at the mark shown -- or very close. Clicking within the map area (or you can drag the 'WCSW1' 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.

The station (or view from the station) is shown here. You can choose the view direction to see the surroundings. Other information (and somewhat larger images) can be found by clicking on the picture.

You can try to find photographs from the area surrounding the site marker by clicking on Find nearby photographs. (There are none)

Data Status

Over the last 28 days, no data was seen on the following dates: 2025-02-18 to 2025-02-20, 2025-03-03 to 2025-03-16.

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  Last 14 days  Last 8 weeks  Last 13 weeks  Last 26 weeks  Last 39 weeks  Last 52 weeks

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.

These values are within the acceptable range. This probably means that your sensor is sited correctly and is calibrated correctly.

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 17 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!
