A disdrometer is a laser instrument that measures the drop size distribution falling hydrometeors.
What Can A Disdrometer Measure?
- Droplet Spectrum of Precipitation
- Precipitation types
- Precipitation intensity
- Radar Reflectivity
- Horizontal visibility
What A Disdrometer Can Be Used For?
- Evaluation of Artificial Rainfall Efficiency
- Soil erosion Assessment
- Monitoring of Soil Momentum
- Rainfall Radar Coefficient Calibration
- Analysis of Regional Rainfall Patterns
- Analysis of Extremely Heavy Rainfall
Can A Disdrometer Replace A Rain Gauge?
No.Their positioning is different. Conventional Tipping rain gauges are mainly used as wmo-approved main rainfall observation equipments, mainly used in the meteorological station system.
The disdrometer is a professional analytical instrument, mainly for scientific research users, independent deployment of the field.
Can A Disdrometer Replace a Visibility Sensor?
Disdrometer can monitor horizontal visibility information, but it is only a subsidiary function, and its monitoring range is small, so it can not replace professional visibility sensor.
