The OTT Parsivel2 is an advanced laser-based disdrometer for comprehensive measurement of all precipitation types.  Accurate yet economical, the Parsivel2 captures both the size and speed of individual preciptation particles and a signal processor classifies the type of precipitation as well as the amount and intensity.


  • Accurate - measures the size and speed of individual precipitation particles, then computes all necessary meteorological parameters
  • Maintenance-free - no moving parts or collection bucket that would traditionally require regular maintenance
  • Durable - continuous, precise precipitation data in all environmental conditions and integrated overvoltage protection
  • Energy efficient - low power consumption and flexible separate controlled head heating
  • Flexible communication - standard ports for RS-485, SDI-12, USB, and impulse for connecting to a datalogger, automatic weather station (AWS), or laptop
  • Innovative design - robust aluminum housing and symmetrically arranged measuring heads prevent moisture from affecting laser band direction

Questions & Answers
Can the sensor head freeze?

An automatic heating system prevents ice buildup on the sensor heads. A temperature sensor in the sensor head takes readings every second and the heating system adjusts according to the value. The sensor head is held at a constant temperature of at least 10 degrees C. Optimum heating output can be guaranteed with a supply voltage of 20 V DC.

What type of precipitation can my Parsivel2 measure?

The Parsivel2 can measure 8 types of precipitation: drizzle, drizzle/rain, rain, mixed rain/snow, snow, snow grains, sleet and hail.

Restoration, Testing, Research and Education

A few years after Ohio became a state in 1803, George Harner arrived in Greene County with a land deed signed by then-President Thomas Jefferson and Secretary of State James Madison. The homestead was largely old forest and wetlands and also included a fen-fed stream—the Beaver Creek. As was the case with much of the Ohio Territory, the forests eventually gave way to land clearing and grain farming. Harner’s descendants, including his son John and John’s wife, Sarah Koogler, continued to work the rich soil for many years to follow. Much of the original property and surrounding land has fallen prey to urban sprawl.

Storms Cause Extended, Elevated Contaminant Concentrations in Urban Streams

Each fall in Puget Sound, coho salmon leave the salt water and swim up freshwater streams. They head upstream to spawn: lay their eggs and die. Death is always the end of this journey for coho salmon, but in streams now running through urban areas, stormwater runoff kills them before they can spawn. This phenomenon, called Urban Runoff Mortality Syndrome, can kill up to 70-90% of coho salmon in an affected area. “‘Woah’ is a pretty common response,” said Kathy Peter, a research scientist formerly at University of Washington Tacoma and the Center for Urban Waters. This phenomenon adds pressure to the Puget Sound population, already considered a species of concern by the United States Fish and Wildlife Service under the Endangered Species Act.

A Nationwide View shows “Evolution” of Water Quality Concerns

Water quality issues are shifting in the United States’ rivers in big ways. Those changes are driven, in part, by the way the land in a watershed is used and they’re big enough that researchers may need to change the way they think about water quality in the American rivers. “What was striking to us was how perceptions of water quality issues from several decades ago may need to be updated,” said Edward Stets, a U S Geological Survey research ecologist, in an email response to questions from Environmental Monitor. New research by Stets published in Environmental Science & Technology in March highlights these shifting water quality issues.
