    It's the classic situation with lots of hints but nothing concrete. ME need to be pushed into getting the radar permanently sorted. To his credit Eamon O Cuiv responded quickly & has said that he will raise it with the Minister.

    When the report says " Sizeable portions of the country have radar rainfall
    estimation rates of less than 30% of the rain gauge observed values." "Overall, it was shown that the Irish radar network is under-detecting rainfall amounts
    countrywide, most significantly along the north, northwest, southwest, and southeast coasts.The mean rainfall detection performance over Ireland by the primary radar product (PseudoCAPPI) was approximately 40% when compared with the rain gauge derived data. In general,the radar at Dublin airport was shown to be performing significantly better than the Shannon radar. Distance from the radar was found to be the primary factor influencing performance,
    with a rapid decline in performance detected beyond ~100km range. Orographic blocking by high ground is creating a number of large radar shadow areas in Ireland particularly in the southeast and southwest, where radar rainfall detection is 10 – 30%. "     the issue is more that just Shannon.

    I'm in Waterford, that's 130km as the crow flies from Shannon and 143km from Dublin. Dublin radar is a good bit blocked by the Wicklow mountains and Black Stairs, Shannon has to go between Shievenamon and the Comeraghs.
    Good part of Kerry and Cork are over the 100km mark as well and mountainous. Performance drops after 100km now put Malin Head in perspective where it is 315km from Shannon and 216km from Dublin, it's a farce.
    When you think about it most of the weather comes from the Atlantic especially storms and having a single radar system that's failing all the time located in the West which is under-detecting rainfall amounts countrywide is a joke. With climate change we can expect more storms and more rain so how can people who's income is weather depended rely on such a system and it's ordinary people that need it as well for very day things. Our setup is more like something out of the 1970's instead of nearly 2020

    How far down the list do you think Met Eireann comes with budgetary allocations?

    Eoghan Murphy is Minister!!!!!!!!!!!!!!!!!!!!!!

    Even if Danny Healy-Rae was Minister, ME would still have its own annual ring fenced budget!

    You can see it for yourself here: Public Service Estimates for 2019 - Met Eireann.

    Update on Shannon which is a complete joke. We have 2 that dont cover all over Ireland, UK has 16 official sites

    https://www.met.ie/shannon-airport-rainfall-radar

    Update 8th November 2019:

    Shannon Airport Rainfall Radar not operational

    "The Met Éireann rainfall radar at Shannon Airport continues to experience technical problems, hence the loss of rainfall radar coverage in the west and south-west of Ireland. We apologise for the loss of this important data.

    Met Éireann are working with the radar manufacturer to find the earliest resolution to the problems to ensure that the issues are resolved and the radar service is restored to safe and reliable operation. However, the radar will be offline until at least the third week in November. We will advise of any further information as it becomes available.

    Met Éireann has already commenced planning for a major programme to expand and modernise the Irish weather radar network."

    Curious about the long repair time I asked a German radar specialist (Christian Wolff) for his opinion:


    "Older radar sets often use parts that are no longer available on the market today. When all stocks have been used up, new parts have to be designed that can be used as replacements. This repair takes much longer. I believe that the high voltage parts break unusually often because of the very humid climate in Ireland."


    Related to accuracy he also said:


    "A weather radar must also measure the exact strength of the echo signal to evaluate, how much raindrops are in this cloud. Because a weather radar becomes less accurate at long distances, not only two radar sets would be sufficient for Ireland but 4 to 6 pieces of these radar sets would have to be distributed in the country."

    Still complaining about the Shannon radar 10 years later, is it a local joke with them or do they take it seriously?

    Really is a farce at this stage. Went to look at the radar today only to remember that its down so couldn't see when the heavy showers were coming. Ended up getting soaked.

    And here's another thread from 2012:-

    Someone in Met E really needs a good kicking for the long-running failure to sort this out.

    Just wondering does Met E use the UK's Met Office radar at Castor Bay (near Lurgan) as part of its coverage?

    495253.jpg

    Doesn't seem to though when looking at the coverage minus the Shannon output, just Dublin it seems. Surely using Castor Bay would improve NW coverage?

    UK has access to Shannon and Dublin and you can see on met.ie site they have to have access to the UK radar to show Wales

    But wouldn't you have more coverage past Donegal if Castor Bay was included? Seems to be only Dublin on Met E's current radar imagery.

    From Caster Bay 100km is Letterkenny after 100km it drops off. Then add in the Mountains and coverage will be even worse

    Belmullet would be a handy spot. Uninterrupted coverage to the West and North.

    Just give you an idea of the coverage and the dark areas are mountains. There is a narrow area with no mountains to the West for the radar to get through. The yellow markers are Official Met weather stations

    Thanks for the tips Mortelaro & Danno.

    @Danno, I got the manual gauge from here:

    https://www.climemet.com/collections/rain-gauges/products/cm1016-professional-manual-rain-gauge

    Received it a couple of weeks ago. Reviews claim it is pretty accurate, which I do not doubt, but having taken it out of the box and jigsawing the various parts together, I can confirm that it isn't a great quality gauge (materially) in that it is quite flimsy.

    My issues: Bottom inner tube holder is not deep enough to keep the inner tube standing straight of its own accord. Has to be held in place by the lid/funnel, which in itself is a very loose fit round the top outer rim. Will have to get some velcro straps or something to stop the funnel lid from blowing off in breezy conditions once I get it set up.

    If I wasn't such a lazy fecker, I'd have put it to the test this morning given the perfect conditions to do such a test. (steady stratiform rain). Will check the forecast later to see if there is any rain forecast for tomorrow and if so, maybe I'll test it then and report back here the results.

    The tipper in my Davis is the older, classic 'double spoon' type. Was not aware of the newer 'single spoon' version! and might invest in one come in the new year. A quick googles tells me it reads on 0.2mm increments as opposed to the 0.3mm/0.2mm in every second increment of the double spoon. Did you have to make adjustments/calibrations on the Davis console itself to allow for this?, or is it just a 'straight out the box' set up?

    Sorry - only seeing this question now. I didn't have to make any adjustments at all. It is much more accurate lately too!

    Got it here: https://www.scaledinstruments.com/shop/davis-instruments/parts/vantage-pro2-parts/rain-collector-parts/davis-7345-147-single-spoon-tipping-bucket-rain-collector-assembly-0-2-mm-metric/

    To be fair, they did say this too;
    However, the radar will be offline until at least the third week in November. We will advise of any further information as it becomes available.

    It's very frustrating not having it online, I rely on it a huge amount.

    Thanks and I accept the point you make but do you have confidence that they would advise the public "of any further information as it becomes available"? I hope I am wrong but I don't have such confidence. I think there is something amiss with an organization that continues to display radar images of the country as a whole without pointing out to the public that a large chunk is missing. Again, I do hope I am wrong.

    I wonder if we could order these radar parts and stick 'em to our SKY dishes? Probably do a better job than that useless Shannon radar.

    Does anyone know if the repairs are being carried out, or are they awaiting parts? I have emailed ME but not had a reply so far.

    They haven't updated their website for almost two weeks now since posting this message:

    "The Shannon Airport Rainfall Radar is currently offline due to a technical fault. Updates will be posted here."


    not very encouraging is it?
