Finally, rain measurement on the ground.
Accuracy that improves your 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:
2.07 inches (52.6 mm).
The closest cumulative value obtained from conventional radar imagery adjacent this
measuring station is
1.61 inches (41 mm),
while RadarToRain estimation data reveals a more realistic value of
2.00 inches (51 mm).

Our products:
→ Realtime and nowcast under construction
→ Rainfall Archives
We deliver high-quality cumulative precipitation archives built from open radar and meteorological data (NOAA, ASOS, OPERA/EUMETNET, Météo-France, etc.) using advanced technology and hydrological methods.
Each archive is accompanied by comprehensive traceability and quality indicators.
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
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.
Collaborative approach: The quality control of our images is mainly based on rain gauges. However, this information is sporadic, limited in number, and subject to known uncertainties. For these reasons, we are open to and welcome any spatial precipitation data you would like to share. This mindset truly inspires us and reflects our commitment to quality and transparency in data validation.
