(author)Wind generation on the North Sea is rapidly expanding. Offshore wind generation is expected to be a major source of energy for the future carbon-free energy system. The onset of this rapid growth is already visible. In the IJmuiden Ver area, 80 kilometres off the coast at Den Helder, a wind park expansion of 4 GW is planned by 2030, and possibly...report 2020

(author)Electro-optical and laser systems are operated world-wide. Their performance in the outside atmosphere is mainly governed by the strength of optical turbulence Cn2. The predictability of Cn2 using weather-forecast models is investigated by performing simulations with the Weather Research and Forecast Model (WRF). The WRF output data were...conference paper 2019

(author), Reiter, D.D. (author)The estimation of absolute road traffic noise levels without including the effects of meteorology is thought to be a major source of error in the estimation process commonly used in the United States.

(author)A series of resonators alongside a road or railway can be used to diffract noise upwards to create a zone of noise reduction behind the elements. The company 4Silence developed the so-called Whisstone, a concrete block with 18 resonators of different depths designed to operate in a broad frequency range. Several measurements at short distance,...conference paper 2018

Ullwer, C. (author), Sprung, D. (author), van Eijk, A.M.J. (author), Gunter, W. (author), Stein, K. (author)Atmospheric turbulence impacts on the propagation of electro-optical radiation. Typical manifestations of optical turbulence are scintillation (intensity fluctuations), beam wander and (for laser systems) reduction of beam quality. For longer propagation channels, it is important to characterize the vertical and horizontal distribution ...conference paper 2018
