whereto get local air pressure reading

Yorker

Can someone please give me a site where you can get local air pressure? I am setting up this. It says to get a local reading

Is hectopascals the same as millibars

Thanks

Yes.

Thanks . The county is there but not the town. i found the town in the meantime on another site.

This unit i have says the pressure needs to be entered the first time but i see it is the same as the local reading.How would this be?.
It synchronises time with a radio transmitter MSF but that does not include pressure does it?

Possibly just pure luck!

Might be best to compare with your nearest Met E station as you never know, your local source may not have adjusted/set their station accurately!!!

What town you in? Possibly then somebody could direct you to an accurate source?

I try to calibrate my weather station when there is a HP over the country. I am about half way between finner and knock airport, so when they are about the same I choose that pressure

You'd probably be nearer Markree Castle then for a pressure reading (considering Finner is at sea level and Knock Airport is about 600 feet ASL).

But dont they give relative pressure readings, which take in to account the ASL factor?
I never noticed markree listed before DoH!

the ME pressure readings will be corrected to sea level

My waether pressure is still keeping track with a local one i found

Jpmarn

All barometric pressure readings given by Met Eireann is based on sea level. Local air pressure could be slightly or substantially lower depending on how high the ground is.

FWVT

Pressure generally drops by 1 hPa (mBar) for every 8 m (27 ft) rise in altitude, but the exact drop varies slightly, depending on the virtual temperature of the airmass. But for our purposes it's accurate enough.

Use this hourly chart to set your sea-level pressure.
