There are no photographs of the station. If you are the site operator and have pictures of this location, then please upload them to Flickr (detailed instructions) and add the two tags 'wxtagged' and 'wx:cwop=c6751'. If the picture is of the weather station itself, then please also add the 'wx:station' tag as well.

Flickr Upload

Uploading picktures to flickr.com is easy. If you do not have a free flickr account, then you need to create one. Just go to flickr and click the 'Create your account' button. You can use a google account if you have one.

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:

wxtagged -- this indicates that this picture is of a weather station or surrounding area
wx:cwop=c6751 -- this indicates the site of which this is a picture
wxstation -- add this tag if the picture includes the weather station.

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.

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)

Wind Vector

The wind vector is the average wind over the relevant period. Note that if the wind blows North for half the time at 2 knots, and then blows South for the other half of the time at 2 knots, then the result is zero -- i.e. North wind and South wind will cancel out.

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. 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.
