(You): Where can I download hourly weather data for the last 30 years (or longer)?
(Charley): Try www.wolframalpha.com. They have a huge amount of historical weather data; it might work for you.
(You): thanks. They’re good about letting you see data a little bit at a time, but I don’t think they allow mass downloads.
(Charley): That’s what I was afraid of, from how you asked. Oh well; good luck.
