    Any ideas what caused this?

    Also your minimum pressure.. is that supposed to be corrected to mean sea level? What's your elevation?

    The differences between roscommon and Dublin are very interesting. Temperature in particular. Joujoujou having a day of 37 degrees and supercell never getting passed 30 - they haven't a notion what real heat is like up in the big shmoke ;)

    Cant wait to see more stats :)

    Privately owned weather station approx. 10 miles west from mine:

    http://www.charlestownweather.com/record.htm

    31 *C on 12.07.2013. :)

    Edit: it's possible data is corrupted somehow - temperature graph from my weather station shows slightly different values. :o

    It seems like a really low value if its corrected to MSL, from what I can see on the Met Eireann website it should be around 950 for that day.

    I only ask the questions to try to help constructively, does your computer software calculate all the statistics itself? It'd just a pity when it looks so good to have a few values in there that look wrong. Unfortunately a huge part of working with weather stations actually goes into checking the recorded data, if you are interested I can write up a list of checks you can do

    A meteorological year that won't be forgotten in my opinion. Very cold start to spring, with multiple snow events (that unfortunately didn't amount to much at all in my neck of the woods) especially in Northern Ireland. Then the very good summer (and convection in August) and stormy weather in the run up to Christmas. There have been far more boring years than 2013.

    I'm about 1.5km from the sea as the crow flies so that definitely moderates any extremes.
    I'd say DOCARCH, who is not to far from me but is a few more KM inland, gets hotter and cooler temps respectively on average and would be more representative of inland Dublin while I'm probably more representative of coastal Dublin.
    That said, if we ever get a mild SW wind my area does very well due to a localised Fohn effect from the nearby Wicklow mountains, unfortunately all too often SW winds are damp and overcast and not associated with good weather, but it does happen from time to time!
    I'd wager it's a lot more sunny here than in Roscommon on average too!

    Never really believed in all the calculations regarding absolute pressure vs. MSL pressure. Absolute pressure (I mean - real pressure I "feel") is the one I'm more interested in. :)

    AMSL pressure is calculated from abs. pressure, altitude and temperature. While I know what temperature is on my altitude, I have no idea at all what it would have been if my altitude was different (if you know what I mean). ;)

    Software reads data sent by weather station and saves it to file. I don't know TBH how it compiles all the stats. :o

    Neither the weather station I have, nor software I'm using are perfect, errors are something I'm aware of. But I'm not pretending (not even dreaming about) to be professional. Unfortunately I've not enough time to clean up faulty entries (not all of them), so maybe together with my stats/reading I publish I should put a disclaimer that they're not error free and nobody should rely on them? :confused:

    Hehe, well just to have a look where and how the sensors are installed, see if we can help point out what caused the strange values, or if people want to compare their own data to yours they can have a look.

    Yeah I know what you mean, its just non-MSL values are nowhere near as useful as MSL and harder to know if they are correct or not.

    Nah no need to do that, unless they are not at the standard heights (e.g. 2m high for air temperature) and installation procedures (rain gauge near a tree or something), and then it doesnt need to be a disclaimer, just make a note to let people know. If you dont have enough time to check them fully then just go for some quick plausibility tests (like you did yourself in the OP for the high rain rate). You can also do the statistics really easily and quickly yourself in excel (MAX, MIN,AVERAGE functions).

    Just some suggestions to try to make some good work great ;)

    Edit: nice judas priest photos by the way :D

    Were you cleaning the machine or something?, i didn't think such a rate was even possible. I had my highest ever rainfall rate last month at 87.6 mm /hr on the 31st and I struggle to imagine how it could have been 6 times harder without the world coming to an end or something!

    In my opinion strange values are caused by sensors themselves - they're part of a cheap Made in China weather station, obviously good only to be treated as hobby toy. Already noticed some extremely weird entries (like -35 *C on June - edited out in above stats).

    Agree that MSL values are useful in terms of regional/national/world weather (ahh, can't describe it better, English is not the language I speak the best :( ), but I prefer to know what pressure is in place I am in, not 140m below it. ;)

    Temperature, humidity and rain gauges 1.8m above the ground, some 6 metres away from house. Wind gauges on top of the house, approx 9m above ground level, 1m above roof top. Not perfect alright, I'll work on it this year (at least I'll try).

    Everything is bigger and better out west Supercell!! :D

    Seriously though I questioned it myself but I was out of the country at the time and never got around to verifying conditions when I got home. I did check the gauge then but it was fine. It is not impossible that the bucket was blocked and somehow 'de-bunged' itself allowing a stream of water through. The gauge is properly sited though, there is a filter in place and both it and the tipping mechanism are cleaned and checked regularly. The calibration was also checked in the last 6 months. I'm pretty meticulous about maintaining the Davis.

    I recorded a similar rate during a brief but pretty spectacular rainstorm with some large hail in the mix on December 18th and having witnessed the intensity first-hand on that occasion I let both records stand. I'll do some more checking.
