Hi Andy,

- see here for the latest (reported) observation for Birmingham airport.

http://weather.noaa.gov/weather/current/EGBB.html

The 'Pressure (altimeter)' setting is how you should set your barometer to
indicate sea level pressure.

Depending on the scale of your barometer - it may show more than one - you
should set either inches of mercury or millibars, equivalent to hPa.

If you want to set your barometer to your local (elevated) pressure (and I'm
struggling to remember the details here), each 28 foot rise in elevation
results in an approximate decrease of 1mbar in pressure.

So, if you are 180m above sea level, that works out that with the current
sea level pressure of 1013hPa, your local pressue should be approximately
1006 hPa (millbars).

I stand to be corrected, of course...

I'm trying to set my new barometer (an "ascot" model, from Aldi; I'm not
expecting miracles...), as advised in the FAQ:

http://homepage.ntlworld.com/booty.w...wfaq.htm#2B.14

but can't find a website with the current information.

I'm in north Birmingham, abut 180m above sea level, and my nearest
airport is BHX.

Any suggestions, please?
