Details

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

| Ask a Question
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.

Mining Waste Cleanup Reveals Interesting Lake Dynamics

For the past decade or so, Dr. Bernard Laval , a civil engineer with the University of Northern BC in Canada, has been researching Quesnel Lake , a large, deep lake with unusual water dynamics. This allowed him an unusually high level of insight into much of what makes the lake tick—and when Mount Polley Mine (MPM) experienced a breach in 2014, causing materials to be deposited into Quesnel Lake, he already had a sense of what the lake's waters looked like. “Our work was inspired by a desire to improve holistic understanding of lake function to help with fisheries management by BC Ministry of Environment (BC MOE) and Fisheries and Ocean Canada (DFO),” explains Dr. Laval.

Narragansett Nature: Remote NERR is a leader in salt marsh stressor studies, crab studies and contributions to Rhode Island environmental policies

Unique among the 29 National Estuarine Research Reserves (NERRS), Narragansett Bay National Estuarine Research Reserve (NBNERR ) is made up of four islands: Prudence, Patience, Hope and Dyer. Protecting about 4,400 acres of land and water, NBNERR is a great place to see a variety of coastal habitats. There are upland maritime forests, coastal pine barrens, sandy beaches, cobble shorelines, salt marshes and open grasslands. NBNERR also has excellent hiking, fishing, clamming and bird watching. “If you want to see us, though, you’ll need to hop on a ferry,” says Bob Stankelis , NBNERR Reserve Manager. “Or you’ll have to take a boat. We’re not that easy to get to. But to be honest, that’s one of the big things residents here like about it: its remoteness.

Acid Rain Data Helping Scientists Tackle Water Quality Issues

Since the 1980s, scientists from the Vermont Department of Environmental Conservation (VT DEC) have been sampling water from acid-impaired ponds and lakes and tracking data related to acidity. The line of inquiry began in response to concerns about acid rain, but DEC scientists now find that the long-term monitoring is not only proving the efficacy of the Clean Air Act but also improving local water quality. Guarding the environment in Vermont Rebecca Harvey is a VT DEC scientist, and monitoring the state's waterways for acidity and other problems falls in part to her. Dr. Harvey corresponded with EM about this work.
