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

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.
