Overview
The OTT Parsivel2 is an advanced laser-based disdrometer for comprehensive measuring of all precipitation types. Accurate yet economical, the Parsivel2 captures both the size and speed of individual precipitation particles and a signal processor classifies the type of precipitation as well as the amount and intensity.
Precipitation Measurement
Complete precipitation measurement, including particle size, volume, and intensity. Precipitation size and type are each calculated into one of 32 classes, as specified by the World Meteorological Organization (WMO)
Monitoring Road Conditions
Precipitation amount and composition are combined with general visibility measurements to provide an accurate picture of road conditions
Early Flood Warning
When combined with water level sensors, the Parsivel2 is the central component in an early flood warning system
Ground Truth Radars
Using drop size distribution (DSD) obtained from Parsivel2 spectra data
Benefits
- Measures the size and speed of individual precipitation particles, then Computes all necessary meteorological parameters
- No moving parts or collection bucket that would traditionally require regular maintenance
- Continuous, precise precipitation data in all environmental conditions and Integrated overvoltage protection
- Low power consumption and flexible separate controlled head heating
- Standard ports for RS-485, SDI-12, USB, and impulse for connecting to a datalogger, automatic weather station (AWS), or laptop
- Robust aluminum housing and symmetrically arranged measuring heads prevent moisture from affecting laser band direction

Applied Research and Innovative Solutions: Creating CHNGES at Western Kentucky University
Long-standing environmental monitoring programs have the power to support a large number of research initiatives and policy changes—however, actually starting these networks can prove challenging. Not only is starting the program difficult, but keeping things operational for decades to come has also been challenging for environmental professionals hoping to make an impact with applied research. Jason Polk, Professor of Environmental Geoscience and Director of the Center for Human GeoEnvironmental Studies (CHNGES) at Western Kentucky University, is all too familiar with this process.

Combating Water Insecurity in Saskatchewan with Real-Time Data
The prairies of Saskatchewan can be described as one of the least water-secure parts of Canada, making water quality monitoring essential for informed resource management in a region already facing water insecurity. While natural physical properties worsen some of the poor water quality conditions in the region, others are connected to land use. Having grown up spending summers on the shores of Lake Huron, Helen Baulch, an associate professor at the School of Environment and Sustainability at the University of Saskatchewan , has always been dedicated to the protection of water resources. Looking back fondly at her childhood playing along the shore, Baulch also recalls the invasion of quagga mussels during her teenage years and watching the lake change as a result.

Seametrics Turbo Turbidity Logger: Boost your Turbidity Monitoring
The Seametrics Turbo Turbidity Logger is a self-cleaning turbidity sensor capable of internally logging over 260,000 data records. The sensor enables researchers, compliance officers, and contractors to monitor turbidity in various applications, from construction and dredging sites to wastewater effluent. Due to its narrow width, this device can be deployed in a range of areas, from small well spaces to rivers and streams. The stainless steel housing and built-in wiper allow the sensor to withstand long-term deployments and reduce the need for maintenance trips. The logger accurately records temperature and turbidity up to a depth of 50 meters.
