Question:
Are there any places on the web that keep an archive of barometric pressure readings at cities or airports, for instance over the past year?

Jeremy,

I do not know of anyplace on the Internet that has free weather data for long time periods.

Otherwise, the best place to look is at the National Climatic Data Center (NCDC), which is located in Asheville, NC. You can find them on the Internet at

www.ncdc.noaa.gov/ol/climate/climatedata.html

However, to get any amount of data, you must pay for it.

There you will find a number of links, including to individual stations. Look at the NNDC Climate Data Online link. There select America, North; United States; Surface Data, Annual Summary. You can then select a state, station and a year. However, you must pay for the data.

Or, go to the Most Popular Data & Products link, then the Downloadable Now link for this data. See products 1 and 4. For these you must pay also. The Free link really doesn't have much useful data.

The Midwest Climate Center also has data, at www.mcc.uiuc.edu. Go to the Available Data Sets and Sample Products link. The Surface Hourly observations include pressure. A paragraph at the bottom of this web page indicates how to order data from the MCC.

Dear Jeremy-

Try this link to get weather data for almost any city in the country.

http://www.wunderground.com/ Enter the name of the city you are interested in the top blank. Then when the weather for that city is displayed, go to the box at the bottom of the page, labelled "historical conditions" and select a date you want. You will get a summary of weather conditions for that day, including the average barometric pressure.
