    These models actually outperform traditional methods on many fronts, including accuracy a lot of the time. They are technically generative AI models, but they're definitely not LLM…

    Really exciting to see NOAA finally make some progress on this front, but the AIGFS suite likely won't outperform ECMWF's AIFS suite any time soon. The underlying architecture betw…

    That seems to be the case from what I've heard.

    Things are changing quickly in this area. Several projects/companies working on AI data assimilation (an alternative route to creating analysis data like ERA5)[0]. Also a lot of co…

    Very interesting, I'd love to hear more about it! In short, yes, we plan to do descents near urban areas if there's a route where we can go down to a safe height and stay away from…

    One of the first ideas we explored was putting an electrolyzer on the balloon to replenish hydrogen over time. Unfortunately right now, for balloons our size and power budget it's …

    We're actually just going to have kids launch our balloons, it's no problem: A person who is 6 years of age or younger who intentionally releases, organizes the release of, or inte…

    I don’t know much about WAPS at all, but generally speaking, we’re only interested in doing weather sensing. As of now, we’re not planning to license the vehicle at all. And genera…

    This might be the coolest use case I’ve heard suggested. We’re not quite at the level where all of this is user friendly enough, but let’s catch up in 9-12 months

    What's the project? Maybe we can help! > Can I ask how you handled the regulatory aspect of launching from urban areas in SF? I can imagine the FAA would have given you some troubl…

    That's the goal. We're all from Florida, so the possibility of reducing the damage caused by hurricanes was a big reason we started the company in the first place. Our balloons are…

    What we're doing wouldn't be possible without the work the Loon team did (and published)

    This is super interesting, I'd never come across ARGO before. Data assimilation is a similar problem for our data, and there currently exist systems for assimilating weather balloo…

    1. Wind speed/direction, air pressure, temperature, humidity, and solar irradiance. We are considering doing atmospheric composition as well, there are a couple of partners that ar…
