The next step to precision,
for better decisions.
Our expertise : Rain at ground level
Standard radar data meets the needs of most users. However, for those who require optimal ground-level accuracy, RadarToRain provides data that is consistent with rain gauge measurements. It combines scientific expertise and artificial intelligence. Our innovative, high-quality approach bridges the gap between radar-measured rain in the sky and the reality on the ground.
Illustration: July 14, 2025, New York City
New York City experienced near-record rainfall with the second highest hourly accumulation ever recorded by ground measurement. The closest cumulative value obtained from the conventional radar image (Marshall-Palmer) near this measuring station is 1.61'' / 41mm and the RadarToRain estimation data reveals a more realistic value: 2.00'' / 51mm.

Our products: Rainfall Archives
Our products are archives of cumulative precipitation, generated from radar data using advanced technology combined with hydrological methods.
Each archive is accompanied by comprehensive traceability and quality indicators.
Each archive is produced without using the same events for training, ensuring independent, robust, and reliable data.
What we deliver:
- Cartesian image files compatible with major modeling tools (GeoTIFF, GeoJSON, etc.)
- Customizable area and time period of your choice
- 1 km² spatial resolution
- Derived from open radar and weather datasets from public providers:
- US: NOAA, ASOS
- Europe: Meteo France, OPERA/EUMETNET
Your trust: Transparent quality validation
Validating our cumulative precipitation images is straightforward: we check
for the
existence of official ground measurements, nothing more, nothing less.
This approach is intended to be transparent and accessible to all.
Confidence/Quality Index
RadarToRain provides an index of quality and traceability for each rainfall archive, ensuring consistency with official measurements before delivery or billing.
Your new opportunities: precision that guides your decisions
Hydrology
Calibrate your models and analyze past floods with data that truly reflects rainfall on the ground.
Agriculture
Assess the real impact of rainfall events and optimize irrigation strategies with accurate historical data.
Risks / Urban Planning
Revisit extreme events and refine flood assessments with corrected radar archives.
Our team and vision: Science and AI in perfect synergy
RadarToRain is a pioneer in producing ground-level rainfall accumulation.
Our breakthrough technology was born from the fusion of more than 20 years of hydrological expertise with cutting-edge technology.
It is based on a proprietary process and years of research and innovation. It was presented at the World Meteorological Organization's Technical Conference (TECO 2024).
Collaborative approach:
Because rain gauges help anchor radar information to the surface but are limited in number and carry known uncertainties, we are open to and welcome any spatialized rainfall data you may wish to share.
This spirit truly inspires us and reflects our commitment to quality and transparency in data validation.
