Knew it!!! I'm in Waterford and was keeping an eye on the skies as I'm working outside. Checked the met site and it lies, it lies!

Is it back up ? Assume ye saw message about it on the met.ie site? So basically if the radar is down, then even if the met site says its meant to be dry for the next few days, thats a load of hogwash?

Nice chocolate product for the the duty free shop located rightly underneath the actual rainfall radar.

So that's why it always breaks when it rains!

How many Shannon radar engineers does it take to change a light bulb ?

Punchlines ?

Well first they have to send for a new bulb from Germany...

Looking at the radar images last night I was surprised at how different the echoes north of Dublin were when Castor Bay (Belfast) was out of action. Dublin's accuracy seems limited even in the absence of nearby mountains (unlike to the south). Images at 00:10 h and 00:15 h. Hopefully they will avail of the tender option to get a dual polarization radar system in Dublin as well as Shannon.

Not seeing what you're seeing there.

I wouldn't think it reasonable to expect too much from Dublin radar beyond about Dundalk.

It didn't pick up as much rain in NI because of the curvature of the earth! Think it did very well in Down/Armagh considering.

If you look at the echoes around Newry (roughly 100 km from Dublin) they are much stronger in the image with the NI radar. My understanding is that the effective range of C band radar (corrected for curvature of Earth) is around 120km but perhaps this correction option is only available for newer radar systems. (Obviously the non quantitative range is further, being about 250 km). We are about 100 km SE of Shannon (with mountains in between) so unless the new radar system has the correction feature we will still get poor coverage. As has been mentioned previously we could do with at least one more radar installation in the country.

We could do with several more tbh.

Due to the curvature of the earth, the minimum altitude of rain the radar can detect increases with distance. So it's no surprise the Belfast radar picked up more rain in Armagh than the Dublin one.
