Rainbow Precipitation Nowcast API transforms real-time satellite observations and radar data, where available, into high-resolution precipitation intelligence for operational use. Rainbow.ai’s proprietary machine-learning and data-fusion models provide point-based forecasts for locations worldwide at approximately 1 km² spatial resolution. Forecasts are refreshed every 10 minutes and extend up to four hours, indicating the timing, movement and intensity of rain, snow and mixed precipitation.

The API is designed for straightforward integration into digital products and operational systems. Aviation and drone operators can assess route risks; mobility and delivery platforms can anticipate demand and delays; agriculture can time field operations; and outdoor, travel and mapping services can deliver timely local guidance.

Radar observations enhance forecast quality in supported markets, while Rainbow.ai’s satellite-based global model extends coverage beyond traditional radar networks. Public benchmarking on WeatherIndex.ai ranks Rainbow.ai first for short-term precipitation forecasting accuracy against leading providers, using a published comparison methodology.
