Meteorological station locations

Comprehensive meteorological measurements are taken by the Hilbre Island weather station situated at the outer part of the Dee Estuary.

It is more representative of local coastal conditions than the Bidston site. This weather station has now replaced the Bidston Observatory weather station.

Hilbre Island weather station was renewed on 10 February 2010.

Hilbre Island weather station #1
This logger and sensor package started taking measurements on 14th April 2004 and has now ceased to take measurements as of 10 February 2010 when it was replaced by the new logger and sensor package.

Bidston Observatory measurements
This station has now ceased to take measurements (26th Nov 2004) due to the POL relocation to Liverpool.

Gladstone Lock measurements
Currently damaged. This weather station will not be replaced due to problems of access to the location.

Important data notes:
1. The rain gauge was off-line between 18th January and 27th April 2005. Data values were recorded as zero values.
2. There is evidence from the data that the rain gauge has been over reading during the windiest periods. This would suggest that the unit is being shaken to the extent that tips are being registered. We have added extra supports to try and prevent this from happening, however if it continues we may have to move the gauge lower down on the tower.
3. Wind sensor was damaged and gradually failed from the 18th December 2009 until 10 February 2010 when replaced.
4. Rain gauged partially blocked by bird droppings (noted on 10 February 2010).

Met stations
15th February 2010
The replacement weather station was installed on the 10 Feb 2010. It will be in a testing phase over the next two weeks.

The solarity and rain gauge sensors are still to be set up (readings are being recorded as near zero values).
