Atmospheric data is the biggest missing piece to improving modern forecasts. We fuse data from our long-duration balloons with state-of-the-art AI models to produce the most accurate weather forecasts.
WindBorne in the news
Global Sounding Balloons
Complete global access, from surface to stratosphere.
WindBorne designs, builds, and operates the only technology that can capture in-situ atmospheric profiles everywhere, including over oceans and the Earth’s most remote places. Each balloon can control its altitude, autonomously flying for weeks at a time.
WindBorne GSB
50+controlled vertical profiles
Multi-week lifetime with autonomous navigation and targeted global reach.
Traditional weather balloon
1vertical profile
A short lifetime of roughly two hours, limited to the area above its land-based launch point.
Proven partnerships
Weather intelligence built for real-world impact.
WindBorne works across U.S. and international governments, the private sector, and world-renowned philanthropic organizations. These partnerships put our atmospheric data and forecasts to work on urgent scientific, operational, and societal challenges.

Persistent global coverage
Our unparalleled atmospheric constellation.
Atlas is the largest balloon constellation in the world and the foundation of our planetary nervous system. We launch hundreds of autonomous, next-generation weather balloons each month and are scaling Atlas to permanently close atmospheric data gaps from pole to pole.
