This is awesome, nice work! In case it's useful, I made a Python package for calculating solar irradiance at altitude: https://github.com/gusgordon/airmass

Takes into account lots of stuff (e.g. attenuation from air, ozone, and water vapor) with the goal of estimating solar power at any altitude/latitude/day/time.

> In 1981, weather disasters caused $3.5 billion in damages in the United States. In 2023, that number was $94.9 billion ( https://www.ncei.noaa.gov/access/billions/time-series ). Does that surprise someone? I think I would not have guessed this growth to be on such a scale. The chart suggests that severe storms are the main culprit.

Not at all. Look at the growth in human buildings in the most at-risk areas and you’ll see why that number is so big now. It’s only slightly due to an increase in severe weather event frequency / severity.

Very cool! How are the balloons transferring telemetry back to earth for analysis, etc? Asking because my research at the University of Oxford was around hyper space-efficient data transfer from remote locations for a fraction of the price. The result was an award-winning technology ( https://jsonbinpack.sourcemeta.com ) to serialise plain JSON that was proven to be more space-efficient than every tested alternative…

Sounds cool. How does it differ from CBOR?

This is awesome, how do you manage climbing and descending with a balloon. Are you compressing the gas on board or using thermals?

I’d love to know, too. If it was me I’d use a small piezo plate on the side of the balloon to do it the same way hot air balloons do. Heat the gas in the balloon = go up, reverse the polarity to cool it = go down. That would be pretty energy inefficient, though, so hopefully their secret method is better.

Loon used pumps and an interior air ballast like blimps do. So clearly there are a few ways.

Yeah, it's a shocking number, and it's just for the US. The global estimates for severe weather are even higher [0], and in places with less infrastructure, the costs are usually more heavily weighted toward human life lost.

Obviously what we're doing can't prevent severe weather from happening, but even very small improvements in accuracy and timelines can have a massive beneficial effect when a disaster does happen. My cofounders and I are all from Florida, so hurricanes are the most visceral examples for us. When hurricanes hit, there are always issues along the lines of "we didn't have the right resources in the right places to respond effectively." Those types of issues can be combated with better info.

Very cool! Are you working on some kind of airborne solar platform?

This sounds like super interesting and meaningful work. Are you hiring, or do you have any advice for your average software engineer on getting into this space?

We're not hiring right now, but definitely check back in a few months. As for advice, there's almost always a place for talented engineers. https://www.climatetechlist.com/ and https://jobs.climatebase.org/ both aggregate jobs at climatetech cos specifically if that's what you want to pursue.
