    Today's update on the ME website:
    Friday 9th August: A major repair is being carried out as a matter of top priority by Met Éireann especially given the current unsettled Atlantic weather pattern. The progress will be updated here on Monday.

    Come on lads.....I've gotten soaked twice this week because of the lack of radar coverage.

    If it was the Airport radar it would be fixed in hours.

    At least, they would have a plan B

    Looking at netweather's radar it looks like they are not using data from the Dublin airport radar, you can see the range ring ends just before Shannon airport which suggests they are only using Belfast radar, but if you go to met.ie website you can see the range ring from the Dublin airport radar extending as far as Cork.

    No, that's just the format they use, they are using the Dublin radar.

    Ball.cocks. you got soaked because it rained.

    We are in a part of the country that depends on Shannon radar for accurate rainfall coverage. Here in Limerick we do get coverage from Dublin but we don't have a clue how intense the nearby rainfall is. I noticed other posters reporting getting caught out because of the lack of coverage towards the south west. Kerry and West Cork have absolutely no coverage at all.


  • Closed Accounts Posts: 1,079 ✭✭✭seefin


    Does Shannon radar cover Cork city? No mention of rain on met.ie today yet a horrendous downpour a half hour ago. Am going to have to stop checking weather online as invariably it's pretty unaccurate on all the sites. Noticed this especially this summer


  • Registered Users, Registered Users 2 Posts: 18,227 ✭✭✭✭JCX BXC


    It would cover the cork area yes. The Dublin radar is very poor at picking up precipitation from that distance. (Curvature of earth, hills in the way etc)

    "Does Shannon radar cover Cork city? No mention of rain on met.ie today yet a horrendous downpour a half hour ago. Am going to have to stop checking weather online as invariably it's pretty unaccurate on all the sites. Noticed this especially this summer"

    In theory but it is not reliable in practice. We are located in west Waterford and it sometimes picks up precipitation and sometimes not. Besides the Earth's curvature the W-E line of high ground from the Galtee's to the Comeraghs is presumably part of the reason for this. It appears to me to work better (but not perfect) at this range for precipitation coming from a greater height such as in a warm front but appears less able to pick up showers.

    Do these radars have to be based at airports? I'm thinking one in the Slieve Blooms would provide a good range for most of the island.

    Slap bang in the middle of Dublin and Shannon though, it would provide very little extra coverage to the country, and would probably just be a waste of money.

    Would terrain not be an issue here?

    They don't have to be at airports. For example what we refer to as the "Belfast radar" is not actually at Belfast airport, but on the south shores of Lough Neagh near Lurgan.

    Here's the exact location, you can see the shadow of the tower and radar housing clearly.

    https://www.google.ie/maps/place/54%C2%B030'07.1%22N+6%C2%B020'34.4%22W/@54.50196,-6.3442331,306m/data=!3m2!1e3!4b1!4m6!3m5!1s0x0:0x0!7e2!8m2!3d54.5019598!4d-6.3428864


    But it does make sense for them to be at airports or at least close to airports for a few reasons. One is because they are more accurate at close range and that's obviously a good thing for warning air traffic about the current weather situation.

    Here's a great read about the "British Isles" (not my words) weather radar network.

    Based on the total weather radar coverage for UK/Ireland it would seem Belmullet (or Knock Airport) would be the most useful place to add an extra station (if there is a more up-to-date coverage map please let us know).


  • Registered Users, Registered Users 2 Posts: 411 ✭✭RoisinD


    Hopefully Shannon back today. Looked at it around 5.00am and thought it had been fixed as it was showing the whole area.


  • Registered Users, Registered Users 2 Posts: 543 ✭✭✭coillsaille


    I see on the coverage chart in the document posted above that the boundary between the 2km and 5km resolution for Shannon is around 10km to my west. Sometimes while watching for upcoming breaks in showers I have seen seen showers materialise out of nowhere around this point on the map. Just curious if the transition to higher resolution at that point explains that?

    That document seems to imply that Shannon airport is in Limerick city, so in reality it would be shifted slightly to the west for Shannon's coverage.

    True indeed. Didn't spot that!

    There may be a resolution effect happening sometime but showers do often materialize out of nothing (as most of us have experienced sometime while enjoying the great outdoors)!

    Yep - I assume we can take it that no news is bad news. :(

    Perhaps Met Eireann should have written: The progress, if any, will be updated here on Monday.

    Complete radar installations have been built from scratch in less time than this is being repaired.

    Tuesday 13th August: We are awaiting delivery from Germany of replacement parts for the Shannon radar this week. Some additional maintenance work and testing will be required when the replacement parts are fitted.

    We will update this article on the expected resumption of service date this Friday.
    Knowing our luck there won't be a drop of rain for weeks after the fix.

    Indeed......we're overdue a long visit from the Azores high. He'll probably arrive for a 3 week stay the same day the radar gets fixed. :)

    God almighty what happened. Did it burn to the ground or what.

    A spider went in and built a web in it.

    Thats how all my rain gauges fail anyways.

    Maybe the giggling pin wore out or it needs some new sky hooks. In fairness it's pretty specialised equipment, it's not like they can just go to Woodies for replacement parts.

    Considering there's threads on the Shannon radar breakdowns on here going back yrs I think that they must indeed be buying the parts from Woodies. Would explain the frequent outages.

    Update on longer term planning
    Shannon Airport Rainfall Radar Not Operational

    The Met Eireann rainfall radar at Shannon Airport is currently not operational due to a technical issue, hence the loss of rainfall radar coverage in the west and south-west of Ireland.

    We apologise for this significant loss in coverage especially given the prevailing unsettled Atlantic weather pattern.

    Tuesday 13th August: We are awaiting delivery from Germany of replacement parts for the Shannon radar this week. Some additional maintenance work and testing will be required when the replacement parts are fitted.

    We will update this article on the expected resumption of service date this Friday.

    (Update on longer term planning: Met reann is in the development stage of a major programme to modernise and expand the weather radar network of Ireland in order to meet the State’s needs to 2040)

    would be interesting to know the make and model of the radar, can guage a bit better the possible logistical issues.


  • Registered Users, Registered Users 2 Posts: 1,552 ✭✭✭dohouch


    Have a look at this radar picture Will it rain today?

    Where is the data in these images coming from?

  • Registered Users, Registered Users 2 Posts: 10,207 ✭✭✭✭Oscar Bravo


    From met eireann

    The maintenance of our Shannon rainfall radar has been completed and it is operational again as of 4:30pm this afternoon


  • Registered Users, Registered Users 2 Posts: 4,816 ✭✭✭Comhrá


    Bring on the rain hail & thunder!


  • Registered Users, Registered Users 2 Posts: 6,675 ✭✭✭ronnie3585


    Excellent. I see that Netweather hasn't yet picked back up the feed from Shannon.


  • Registered Users Posts: 125 ✭✭ecowise


    Great that it is back. For the record that is 13 days downtime as far as I can tell. Is that correct and has it ever been out of service that long before (other than for upgrades)?


  • Registered Users, Registered Users 2 Posts: 6,675 ✭✭✭ronnie3585


    Netweather is back using the Shannon feed.

    Comparing past screen grabs it seems they have put a black outline around the Island which makes it stand out more. The radar echoes are the same so not a big change.

    Still can't zoom out to see the whole country and the NI radar is gone again :rolleyes:
