IR based Snow Surface Temperature Measuring Probe
Brief Description
Prediction of avalanche occurrence demands the measurement of snow and meteorological parameters of the avalanche formation. For this purpose, specific kind of state of the art instruments and systems are needed. These must be capable of unmanned data collection from highly inaccessible areas in deep Himalayas. All the objects emit infrared radiations, which are generated by the vibration and rotations of atoms and molecules with in the matter. As the temperature of the object increases the molecular activity in the object increases causing the object to generate more energy. By using this concept CSIO has designed and developed an infrared technique base Snow Surface Temperature measuring probe/sensor. It has been interfaced with automatic weather station installed in deep Himalayan region. The sensor is used to measure the snow surface temperature using non-contact remote sensing method. The snow surface temperature data is used in snow cover melting and run-off water modeling.
Salient Features
- Tight weatherproof mechanical design has been incorporated.
- System can be directly interfaced to Data Acquisition System.
- Sensor operates round the clock for several months under severe conditions.
- The sensor operates in the high relative humidity upto 100% and a wind speed of the order of 200 Km/ h.
- Resolution in temperature measurement is 0.10 C.
- Low cost and state of the art instrument.
Applications
- Used to measure snow surface temperature at deep Himalayan regions.
- Can measure the temperature of any object between -40 oC to 100 oC.
- Assessment and forecast of river water level.
- Forecast of flood and water rise due to snow melt.
- Snow hydrological studies.
- Snow cover modeling and hydrological computations.
Benefits
The developed technology will be used as one of the component for prediction of snow Avalanches
