There is already a thread on the Shannon station due to the question over its suspiciously high temperature readings lately. This started a debate on the quality of the siting of this and other stations, so here is one thread aimed at providing a reference to as many stations as possible (coordinates, aerial imagery, etc.).
Met Éireann have a page on all of their synoptic stations (excluding Airports) here, and one for their airports here. Here's a table summarising all, including the regional airports. The coordinates shown are the centre of the instrument enclosure, taken from the Bing aerial image.
Stations should be sited in such a way as they can represent conditions of the general area. The station enclosure should be level and covered in short grass, well away from buildings, walls, paved areas, etc. The temperature sensors should be free from extraneous heat and radiation, and for this reason the they are housed in a Stevenson Screen, which allows natural ventilation of the air through its louvred sides while protecting the sensors from direct solar radiation. Rain gauges are usually sunk into circular pits in the ground to minimise the effects of undercatching due to wind turbulence. Anemometers are located on masts 10 metres above the ground, located several times that distance away from buildings and large trees to minimise turbulence effects.
Departure from the above guidlelines can lead to biases in longterm climate trends for that station. In the case of Shannon, it's been discovered that it was relocated to an enclosure close to a large carpark some time after 2005. This has possibly led to false high temperature readings in times of sunny weather and easterly winds. A recent record temperature in Motherwell, Scotland, was since rejected by the Met Office as it was found that a vehicle had its engine running too close to the temperature sensor.

Not for me, just bring me to the search front page. Maybe you have to be signed in?
Bing links work as in it brings you there but not sure what I am ment to be searching for when there
No not for me either.
I've been trying recently to find a full list of stations they use for climatic data. Is that the
full list above? Was Mount Juilet dropped?
Also the only data I can get from Waterford airport is the latest reports which only covers the most recent couple of hours. Is this published somewhere else?
BTW anyone know who runs the Killarney National park weather station. I was only looking at it yesterday wondering if it was still active.
Gaoth Laidir, the problem with the bing links is they add "</td><td>" to the end of the url for some reason. If I copy and paste the text they work fine.
It looks like you have an empty column at the end of the table (thin grey vertical bar with a "_" at the top), so probably some formatting issues causing the problem.
The above list is only the hourly stations on their website plus a few more regional airports. You can see reports for the airports here. Airport codes are four letters, EI**, where the ** is the individual identifier.
I took a few photos of the various weather instrumentation at Dublin Airport yesterday. There are two 10-metre anemometers, the main one is located midfield, south of the main runway, but I notice a new one further east, at the touchdown zone of R28. It's beside the Glidescope antenna array and therefore probably used by the tower when issuing landing clearances on that runway (I assume).
At the midpoint of the runway there is another RVR sensor array with its own automatic weather station and 2-metre anemometer. These would most likely be part of the RVR system and used as a more precise indicator of conditions right at that point.
Here's all the info on that refected record at Motherwell. Look at the stevenson's screen and the crap that's surrounding it. Ironically it was an ice cream van that was the source of extra heat.
There is some more detailed info on some of the synoptic stations in the Subsets in the Ireland BUFR files, such as this one. It gives the height altitude of east station and its barometer, which in the case of the airports seems to be in a building several floors above ground level, but just 1 metre at the automatic stations. Exception: Casement's barometer is 4 metres BELOW station level (obviously some other part of the airfield).
|Station||WMO ID||Station altitude (m amsl)||Barometer altitude (m amsl)||Temperature sensor height (m agl)|
I spent ages looking for that station on maps when that was first reported, suspected it was near tarmac but never would have even thought to look there, ridiculous location
Does anyone know how the proposed new runway at Dublin Airport could affect the Airport station?
Will it have to be moved again or will it remain in the same place but potentially be affected by the new building works?
Not at all, the new runway would be about 2km away from the met station at it's closest point.
Should have no affect on the current position
