Forecast
Proprietary weather models built on major global and regional data sources, enhanced with state-of-the-art AI — delivering deterministic and probabilistic forecasts across standard meteorological variables.
High Performance Weather Services
High-precision, coordinate-referenced meteorological data — AI-enhanced nowcasts and forecasts to 16 days, observations, and severe-weather alerts. High-performance REST/JSON APIs and MCP integration for media, energy, travel, and AI applications.
Data
High-precision, coordinate-referenced data products — from short-range nowcasts and forecasts out to 16 days, through archived observations and severe-weather alerts.
Nearcast
Short-range forecasts updated every minute with recent radar, satellite and observation data. Battle-proven algorithms in combination with our latest AI models for unmatched accuracy.
Observations
Surface, radar, and satellite-derived measurements quality-controlled and gridded for assimilation, validation, and analysis workflows.
Severe weather warnings
Timely alerts for thunderstorms, heavy rain, wind, and other hazards — georeferenced polygons and metadata for push notifications, map overlays, and automated response workflows.
API
High-performance weather data services — available as custom on-premises deployments or fully managed cloud infrastructure, built for production-scale integrations.
REST/JSON API
Versioned endpoints with OpenAPI documentation, API key authentication, and predictable rate limits for production workloads.
High-Performance
Autoscaling services with millions of requests pre minute and single digit millisecond response times.
High-Availability
99.9% uptime SLA for our services. 24/7/365 monitoring of external data sources. Individualized support and training for our customers.
Map services
Raster and vector map services for all major map libraries as well as high-performance custom-built mapping solutions.
Use cases
Weather data integrated into operational and analytical systems across industries.
Media & publishing
Power consumer-facing weather pages, apps, and widgets with fast, reliable forecast and observation feeds. Tile-based map layers and JSON endpoints scale to high traffic while keeping editorial control over branding and presentation.
Energy & renewables
Improve solar and wind yield forecasts, optimize dispatch schedules, and model grid load under varying weather regimes. Historical archives support PPA risk assessment and long-term resource planning.
Travel & leisure
Embed destination forecasts, severe-weather alerts, and seasonal outlooks in booking flows, trip planners, and outdoor activity apps. Hyperlocal data helps consumers decide when and where to travel, hike, or ski.
AI & MCP integration
Structured weather data exposed via Model Context Protocol (MCP) — enabling AI agents and LLM applications to query forecasts, observations, and alerts as machine-readable context for automated workflows and grounded decision support.
Metrics
Operational metrics from our production data pipeline and API infrastructure.
