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.

E. Coli in the Los Angeles River: How Much is Too Much for Recreational User Exposure?

Although the Environmental Protection Agency (EPA) and other agencies have already answered this question by setting guidelines for E. coli limits in water used for recreational purposes, the question is again being debated in Los Angeles. This is because the city adopted a new protocol in October of 2017 that mandates closing the Los Angeles River to recreational users whenever E. coli levels are too high. E. coli in the Los Angeles River The City of Los Angeles approved the new river protocol which was developed by the City of Los Angeles Department of Sanitation (LA SAN), the Los Angeles County Department of Public Health, the City of Los Angeles Mayor’s Office, the Mountains Recreation Conservation Authority, and the Los Angeles County Department of Public Works.

Can Better Technologies Save Endangered California Salmon?

Up until the 1800s, salmon were so plentiful in California that these “ bits of silver pulled out of the water ” could be observed ascending the waterways, thousands at a time, each season. However, decades of logging, the construction of dams, and other human interventions have changed the waterways of the state so significantly that the range of the salmon has been permanently altered. Now, a team of scientists collaborating through the Interagency Ecological Program have developed a plan to improve salmon management and, hopefully, help save the species. Team members from NOAA Fisheries, the California Department of Water Resources, the U.S. Fish and Wildlife Service, the California Department of Fish and Wildlife, the U.S. Bureau of Reclamation, and the U.S.

Weather Extremes Shaking Up Fouling Communities in Urban Estuaries

Marine fouling species may seem to be lowly creatures, situated toward the bottom of that portion of the food chain animals comprise. However, these filter-feeding invertebrates that make their homes on hard underwater substrates such as the hulls of ships are among some of the most successful invasive species. Their secret is simply their ability to latch onto human vehicles and survive. Now, new research on the fouling community in the San Francisco Bay indicates that a single wet winter and the change in salinity that high levels of precipitation bring can knock back the advance of these hearty creatures. Marine biologist Andrew Chang of the Smithsonian Environmental Research Center’s Tiburon, California branch published this new research in December of 2017.
