AI Weather Model Developers

The Data Layer for
AI Weather Models.

High-resolution, high-frequency, global-scale. The fuel your AI forecasts have been waiting for.

The Problem

AI weather models are constrained by inadequate data that limits their potential for breakthrough forecasting capabilities.

Sparse Training Data

Currently less than 0,1% of the atmosphere is measured with sensor-grade accuracy, creating massive data gaps that limit AI model training effectiveness and prediction accuracy.

Low-Resolution Inputs

Conventional weather data sources typically offer low spatial resolution and update intervals of 3 to 6 hours, different from high-precision AI models that require dense, real-time atmospheric profiling.

Performance Bottlenecks

AI weather models are constrained by data quality and density limitations, resulting in reduced short-term forecasting visibility, poor performance in data-sparse regions, and limited ability to capture rapid atmospheric changes.

The Missing Data Layer for
AI Weather Models

AI weather models need dense, high-frequency atmospheric data to reach their full potential. Current data sources create bottlenecks that limit model accuracy, more precise warning capabilities, and local forecasting accuracy. Skyfora provides the critical upstream data layer that AI models have been missing: foundation models requiring vast, diverse datasets and real-time prediction pipelines demanding ultra-low latency and high-frequency updates.
