Record-breaking AI forecasts

WindBorne’s deep learning forecast model, WeatherMesh, creates the most accurate global medium-range weather forecasts in the world. WeatherMesh’s AI underpinnings allow it to process both vast training data and live inputs at scale. It’s purpose-built for powering real-time operations, including our own constellation.

Complete 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 maintain or transition between any altitude from sea level to 20 km, autonomously flying for weeks at a time.
