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

Government Officials Ignore Health Risks Associated with E. coli in Boulder Creek

Since 2003 harmful bacteria Escherichia coli (E. coli) levels have created a health risk to recreational users in Boulder Creek. Boulder Creek has been designated as an impaired stream and is not meeting an EPA health-based water quality standard. Concentrations of E. coli increase from the mouth of Boulder Canyon to the University of Colorado-Boulder and beyond based upon data collected by the City of Boulder according to information published by the CU Independent and the Boulder Camera . EM spoke to environmental engineer Art Hirsch of the Boulder Waterkeeper , who is advocating for greater accountability from all entities that own property abutting the stream. “E.

New Monitoring Site for Ocean Acidification in American Samoa

The National Oceanic and Atmospheric Administration (NOAA) and the Pacific Islands Ocean Observing System (PacIOOS) at the University of  HawaiĘ»i at Māno a , in collaboration with other partners, recently deployed a new ocean acidification (OA) monitoring site in Fagatele Bay National Marine Sanctuary , American Samoa. Derek Manzello , a coral ecologist with NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) in Florida, is the lead PI of ACCRETE: the Acidification, Climate and Coral Reef Ecosystems Team at AOML. Dr. Manzello connected with EM about the deployment. “ACCRETE encompasses multiple projects that all aim to better understand the response of coral reef ecosystems to climate change and/or ocean acidification,” explains Dr.

Extreme Wave Heights, Ocean Winds Increasing Globally

Around the world, extreme wave heights and ocean winds are increasing. The greatest increase is happening in the Southern Ocean, according to recent research from the University of Melbourne , and Dr. Ian Young corresponded with EM about what inspired the work. “Our main interest is ocean waves, and we are interested in wind because it generates waves,” explains Dr. Young. “Ocean waves are important for the design of coastal and offshore structures, the erosion of beaches and coastal flooding, and the safety of shipping.” Waves also have a role in determining how much heat, energy and gas can be trapped in the ocean. “The major reason why changes in wave height may be important is because of sea level rise,” details Dr. Young.
