The probe that helps you measure snow water equivalent on a large scale.
Patented muon-counting & CRNS technology measures snow water equivalent and monitors seasonal water reserves
Snow Water Equivalent
Track snow water equivalent on large scale
Finapp's patented CRNS probe combines neutron and muon counting to measure snow water equivalent (SWE) in real time, covering about 40 m in diameter, with a saturation limit of over 10,000 mm/eq (corresponding to 20–25 m of snow depth), without relying on sparse manual measurements.
- Patented Muon Technology | Saturation >10,000 mm/eq
- Large-scale visibility (up to 40 m coverage)
- Continuous, real-time monitoring
Track snowpack evolution through the season
Monitor accumulation and melting phases over time to understand how water availability changes during the season.
- SM monitoring in snow-free periods
- Accumulation tracking
- Melt phase analysis
Water reserve forecast
Improve forecasting of water availability
Unlike conventional approaches, which can be affected by bridging phenomena, Finapp's SWE system directly measures snow water equivalent in real time. Its snow water equivalent data is validated against reference measurement , providing a precise picture of actual snowpack conditions.
- Water availability forecasting
- Accuracy validated against the manual coring reference data
- Ground validation for model scaling
Snow monitoring
Measure snow water equivalent without manual ground expeditions
Continuous measurement reduces the need for manual snow sampling, particularly in remote or hazardous areas where field coring is costly, difficult, or unsafe.
- No manual snow sampling
- Continuous datasets
- Remote monitoring
The probe enabling basin-scale snow water equivalent monitoring
Finapp’s patented muon-counting probe uses a dual-sensor system: an air sensor and a buried ground sensor, to measure snow water equivalent across the surrounding snowpack. Compact (≈8 kg) and solar-powered, it installs above ground with no calibration required, continuously measuring SWE up to a 10,000 mm saturation limit.
| Dual air/ground probe system |
| SWE measurement up to 10,000 mm/eq (patented) |
| Large-scale footprint, about 40 m diameter |
| Continuous monitoring, + soil moisture sensing in the snow-free season |
Snow Water Equivalent FAQ
Find answers about deployment, measurement coverage and snow monitoring capabilities.
-
Finapp sensors measure variations in neutron counts caused by hydrogen in snow. These variations are used to estimate snow water equivalent continuously and without invasive sampling.
-
A single probe can represent snow water conditions across a large surrounding area, making it suitable for basin-scale monitoring.
-
No. The probe is installed above ground and measures snow water content across the surrounding area without being buried in the snowpack.
-
Yes. Snow water equivalent data can be integrated into hydrological and forecasting models used for water resource management.
-
Yes. The probe is designed for remote deployments and transmits data through cellular connectivity.
