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

Eoghan Murphy is 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

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:-

https://www.boards.ie/vbulletin/show...p?t=2056821074

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?



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
