  • 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® ...

  • A comparative study of prognostic MM5 meteorological modeling with aircraft, wind profiler, lidar, tethered balloon and RASS data over Philadelphia during a 1999 summer episode

    This study presents a comparative evaluation of the prognostic meteorological Fifth Generation NCAR Pennsylvania State University Mesoscale Model (MM5) using data from the Northeast Oxidant and Particle Study (NE-OPS) research program collected over Philadelphia, PA during a summer episode in 1999. A set of model simulations utilizing a nested grid of 36 km, 12 km and 4 km horizontal resolutions ...

  • Evaluation of dispersion model parameters by dual Doppler lidars over West London, England

    Urban dispersion models have parameters for the turbulence and mixing height. We identify the parameters in meteorological pre-processors, which are, in principle, measurable by pulsed Doppler lidar. This technique measures radial velocity from the Doppler shifted wavelengths of backscattered laser pulses. First results obtained from single and dual lidar operations are described. Using two ...

  • 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 ...

  • 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 ...


  • 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 ...


  • CU-Boulder leading study of wind turbine wakes

    While wind turbines primarily are a source of renewable energy, they also produce wakes of invisible ripples that can affect the atmosphere and influence wind turbines downstream -- an issue being researched in a newly launched study led by the University of Colorado Boulder's Julie Lundquist, assistant professor in the atmospheric and oceanic sciences department. The study, called the Turbine ...


  • ADMS 5 Flat Terrain Validation Kincaid, Indianapolis and Prairie Grass

    1 Introduction This document presents a summary of ADMS model results compared against three well known field data sets: Prairie Grass. Kincaid and Indianapolis. Results are also presented for two U.S. models: ISCST and AERMOD. ISC ST is the United States Environmental Protection Agency model. It is a so-called 'old generation' model, similar to the UK R-91 model, based on the ...

  • Hurricane response emergency modeling with InfoWorks WS

    The island of Jamaica is located in the Caribbean Archipelago, 90 miles south of Cuba, 600 miles south of Florida and 100 miles south-west of Haiti. It has a population of 2.6 million, 800,000 of whom live in the metropolitan area of the capital, Kingston. The island is mountainous, with a distinct east-to-west ridge and a dramatic relief change in the east. Like the rest of the region, ...
