Creating weather certainty. We fuse unparalleled data from our constellation of smart, long-duration sensing balloons with state-of-the-art AI forecasts.

By now, you’ve probably heard about the historic March heat wave unfolding in the West Coast this week (unless you live under a rock, which would serve as a cool shelter from the heat). The forecast temps alone are impressive w/ many locations expected to break their all-time March heat records!

(1/4) You’ve likely heard of the upcoming major snow and ice storm expected to affect large swaths of the country this coming weekend. If you're heading to AMS 2026 (like our met team), you might be wondering how the storm may evolve. Let's use WeatherMesh-5c to look at the upcoming forecast.

Where traditional physics-based models might struggle, AI models can excel. WeatherMesh-5c spotted the NE forecast change earlier than other major model suites, becoming the first to abandon the Northeast warmup and correctly resolve the storm's big-picture evolution.

We are honored to share that WindBorne Atlas was named one of TIME's Best Inventions of 2025. This recognition represents more than an award since it validates our mission to transform weather forecasting through innovative data collection technology. Here's to building a planetary nervous system!

"As we’ve flown balloons closer and closer to tropical cyclones, we’ve noticed that there’s a thin layer of convergence in the upper troposphere, between approximately 8 to 10 kilometers in altitude." - John Little Read more about how we flew our GSBs into Hurricane Henriette on our blog.

Q: "How far in advance can you spot a record-setting East-Coast heat wave, and how steady is your signal run-to-run?” A: * WeatherMesh-4 showed a consistent signal for above normal temps 15 days out * IFS mean begins a consistent sig ~13 days * AIFS and GEFS mean begins a consistent sig ~11 days
