  • A preliminary analysis of measurements from a near-field pollutants dispersion campaign in a stratified surface layer

    In order to study pollutants dispersion in a stably stratified surface layer at small scales, a pollutants dispersion field experiment programme is being conducted on the site SIRTA in the southern suburb of Paris. In a preliminary campaign held during the winter of 2012 with continuous gas releases, we had 12 ultrasonic anemometers measuring wind velocity and temperature at 10 Hz, and six ...

  • Introducing The RNRG Goalpost Boom

    We are happy to introduce a new goalpost mounting solution for installing redundant class 1 anemometers. This new boom, designed specifically for use with our 80m XHD TallTower, positions anemometer cups at exactly 80 m above ground level—2.5 m away from each other—and 1.99 m ...

  • Weather Data for Noise Monitoring

    “Weather conditions are the single largest variable factor in how sound travels over large distances,” says Steve Bilawchuk principal partner and engineer at ACI Acoustical Consultants Inc. “Wind speed and wind direction are of crucial importance.” ACI is an acoustical engineering consulting company based in Alberta, Canada, which uses ...

  • How to Keep Your SymphoniePRO Data Secure

    Data matters. The accuracy, consistency, and yes, safety of measurement data keep many wind developers and analysts up at night. Customers often ask about the digital and physical security of RNRG instruments, so I sat down with Michael Fisher, product manager for our wind resource assessment (WRA) line, to get answers to the most common questions. Q: Why is data security important? ...

  • Future inside – smart environmental sensing technology

    SHM30 snow depth sensor in Antarctica (photo: Alfred-Wegener-Institut, Helmholtz-Zentrum Bremerhaven) A lot of sensing technologies have changed recently: Ultrasonic wind measurement replaces cups and vane systems, closed anemometer designs offer better protection from ...

  • Measuring Offshore Wind Resources

    To select the right offshore wind site, estimate the future energy output of a wind farm, and determine the best layout for the turbines, project developers must conduct wind resource assessment (WRA) campaigns on site. This is a critical phase of the successful development of wind farms. WRA campaigns on terrestrial sites have traditionally been performed using meteorological towers equipped ...

  • Weather claims and wind safety

    Anybody working in the construction industry either here in the UK or anywhere else in the world is likely to know that the weather can present us with particular hazards. While rain, ice and snow are particularly dangerous to work in, we must always be aware that the wind is also likely to make conditions unsafe, particularly for those who work at height and those who ...

  • NWS Weather Spotter Relies on RainWise - Case Study

    Tom Haraden is a retired National Park Service Ranger and current National Weather Service spotter in Utah. "I like that [my MK-lll-LR] is reliable, wireless, accurate, measures maximums and minimums," Tom says, " and measures eight parameters. I guess my favorite part is having an accurate barometer. I can predict the weather here with only that. We have the display hung where the kitchen, ...
