Sounds pretty cool, actually. You may want to reach out to specialized/boutique weather data firms and broker a supplier deal. There are larger weather companies out there that would love to aggregate your stuff to improve their current offerings (kind of a whole being greater than the sum of the parts model). I wouldn't try to go strike a deal with, say, power companies or insurers or whomever the end user may be. By itself, your data may not be very valuable, and these larger companies likely already own the relationships that would take you a long time to forge.

But, if any when you are sitting down with these companies, be smart in the contract signings. I know a few meteorologists who got their early cash flow from supplying data, but they negotiated a bad contract and it was a rough experience. I've also heard some stories of great relationships that led to exits, so each company is different.
