Question:
is there a web site that might have the barometric pressure for each day for the last year or so (for chicago area)?


Replies:
Yes, this is easy - see the Argonne National Laboratory Environmental Research Division, Atmospheric Section data page at gonzalo.er.anl.gov/ANLMET/text (the ANLMET must be in caps). There you will find the last several years of data. Click on the 2000 link, for instance, and you will find links for each month. Go into one of those links and you will find data for each day of the month. At the very bottom of the listing are two summary tables, one with hourly averages and the very last one with daily averages (which is what you probably want). The pressure (title BAROM PRESS) is in kilopascals (kPa). Multiply by 10 to get millibars, or multiply by 0.2953 for inches of mercury.
