I'm looking to get historical information on the magnitude of rainfall events for a given location (Boston, Massachusetts USA). For example, to create a histogram of rainfall events by precipitation amount for a given location. So far, I've only found "last 3 days" or "last month" -type data sets from NOAA and others. I'd like many years worth of data if possible.
I'm not looking for a shapefile, so much as tabular-type data (database, Excel, CSV, etc). Data doesn't need to be available for any arbitrary Lat/Lon, but could be for nearby POI, e.g. airports.
