The site coordinates appear to be of low precision, and the station may be anywhere within the marked area. Clicking within the map area (or you can drag the 'PARL' 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.
The location information for this site was gathered from 6 data sources. The possible locations for this site are up to 6.8 miles away. This makes it possible that the location chosen is incorrect. 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.
Latitude: dummy (deg min sec), dummy (decimal), dummy (LORAN)
Longitude: dummy (deg min sec), dummy (decimal), dummy (LORAN)
Estimated elevation is dummy meters (dummy feet) from dummy.
There are no photographs of the station. If you have pictures of this location, then please upload them to Flickr (detailed instructions) and add the two tags 'wxtagged' and 'wx:metar=parl'. If the picture is of the weather station itself, then please also add the 'wx:station' tag as well. Please geotag your images, and those coordinates may be used in the estimation of the location of this site.
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)
Status: Status: None found.Clicking on the map above will redo the search centered on the clicked point.
If any images are of the weather station, then please click on those images, and add the 'wxtagged' and 'wx:metar=parl' tags to those images. For the station itself, please add the 'wx:station' tag as well. Some users do not permit other users to add tags to their images. In these cases, just add a comment to the picture asking the photographer to add the tags themselves.

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.

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. Since this station has not been reporting continuously during the analysis period (it missed 1 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.
