  • New methods for measuring the wind

    Although computer models of wind flow over terrain have improved dramatically in the past few years, there is still no substitute for data recorded at the site. So you want to build a wind farm. Good for you. With the global drive towards a low carbon economy, it is surely the right way to go for many individuals, companies and, indeed, Governments around the world. As information from the ...


  • Amassing Wind Information

    Wind is a variable resource, but not an indecipherable one. Second Wind encourages harnessing the full range of wind sensing technologies that are available today. When it comes to wind information, much attention is focused on the choice of wind measurement technology and data collection practices in wind resource assessment and project design. Right now, wind data plays a limited role in the ...


  • 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 ...

  • Compilation of wind energy assessment software and wind energy assessment in the northwest of Iran

    Development trend of wind data assessment software, Visual WIDA®, is discussed in this paper. In the beginning, theories and standards required for wind energy assessment which are used in the software are introduced and some methods provided by the writers for the calculation of the main parameters are described. Afterwards, capabilities of Visual WIDA are illustrated in detail. In this ...

  • Solar/wind power for noise monitoring terminals

    Solar Power Solutions A noise monitoring terminal’s (NMT) low power consumption and its ability to operate fully without power hungry cooling and heating units inside its enclosure mean that it is suitable for power from solar panels. The NMT may be continuously powered by battery which in turn is kept charged via solar energy. This solution is most appropriate in areas where there ...

  • Evaluation of inversion strengths and mixing heights during extremely stable atmospheric stratification

    We have compiled data from Finnish sounding stations and classified the inversions according to their total depth and the stability of the boundary layer. We studied the persistence of the inversions and the influence of cloudiness and wind speed on the temperature gradient. Additionally, we addressed the specific problems of an urban area, using measurements from a meteorological mast situated ...

  • ADMS 5 Buildings Validation Bowline Point Site

    1 Introduction The Bojivline Point1 site is located in the Hudson River valley in New York State (Figure 1). There are two stacks of height 86.9 m, close to the western shore of the river. The emissions from the stacks were buoyant and varied hour by hour, and very close to the stacks there was a complex of buildings. The site itself was rural and the terrain ...

  • Using Lidar for WRA Campaigns: Your Questions Answered (Part I)

    In the course of conversations with wind developers new to Lidar technology, a number of questions seem to come up regularly. In this and future blog posts, I will attempt to answer these questions in some detail to benefit others who might be pondering them as well. Two very practical questions have to do with how WINDCUBE® ...

  • 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 solar is transforming an old mining town

    You hike over the crest of the hill and there it is: 96 sun-tracking solar masts, each with 42 solar modules — 4,032 modules in all — perched on the side of a hill with the beautiful Rocky Mountains in the background. It’s called the SunMine project and it’s all part of the reinvention of Kimberley, B.C., from mining town to a clean tech, tourism town of the ...

  • Green Careers: 400,000 environmental jobs by 2015

    The House of Commons Environmental Audit Committee (EAC) is currently conducting an inquiry into the prospects for green jobs and policies aimed at increasing employment in environmental industries. It will consider how the UK can maximise the environmentally positive opportunities arising from changes in public spending and how this might help with employment during the recession. The report ...

  • Q&A: Patrick Wagnon on glaciers and climate change

    Patrick Wagnon is a glaciologist at the Institute of Research for Development in France, and a visiting scientist at the International Centre for Integrated Mountain Development in Kathmandu, Nepal. As a global ‘glacier chaser’, he has summited some of the highest mountains in the world, including the 8,516 metre Lhotse in the Himalayas. In 2001, Wagnon and his fellow glaciologist ...
