![]() If I am not mistaken, Ordnance Survey maps show elevations. Check before you buy, of course. There are probably several different types of maps available. Also, the nearest airport or weather bureau should give you the data you need to set your barometer. Assuming that the barometer reading published by your nearest airport or similar source is standardized for altitude (most of the time it is), then all you do is adjust your barometer to the exact same reading published by the airport, etc. Note: if you are at a significantly different altitude from the site you using as a reference, then you must do a further adjustment to compensate for that change in altitude. This is even if you took your barometer right to the airport and set it as mentioned above. Also, you want to be no more than sixty miles from your "benchmark" barometer--preferably much closer. Another possible benchmark or source is a local weather channel on TV (if applicable in your area) and weather-related web sites maintained by government or private individuals. Do a google search for such web sites (in the latter case). Phone HM Government and ask them where your nearest government weather bureau is and how to contact them. There is lots of information on the internet if you do a goodle search on "aneroid barometer adjustment" or similar search strings. This information will acquaint you with important basic issues surrounding barometers of all and several types. Regards, Ian D.

They do indeed ... and now you don't even need to buy the chart to do this task: here is the new entry which I am working up for the uk.sci.weather FAQ which deals with this. The best way to determine your *altitude* above mean sea level (again UK only), is to use an Ordnance Survey map with contours marked at 5m intervals. Use this link:- http://www.ordnancesurvey.co.uk/oswebsite/getamap/ accept the terms/conditions, then use the search facility to find your location and zoom in to the maximum extent. It should be possible to determine with acceptable accuracy the height using the contours and spot heights given.
