de Jong, A.N. (author), van Eijk, A.M.J. (author), Fritz, P.J. (author), Cohen, L.H. (author), Moerman, M.M. (author), TNO Defensie en Veiligheid (author)The knowledge of the atmospheric aerosol characteristics is of great importance for the range performance of Infrared and Electro-Optical sensor systems. The composition, the concentration and the size distribution of aerosols determine their scattering behavior as function of wavelength and thus their attenuation of light beams. When studies...conference paper 2007

TNO Defensie en Veiligheid (author), Kuśmierczyk-Michulec, J.T. (author), van Eijk, A.M.J. (author)The variation of the extinction coefficient with wavelength can be presented as a power law function with a constant (related to the power factor) known as the Ångström coefficient. When the particle size distribution is dominated by small particles, usually associated with pollution, the Ångström coefficients are high; in clear conditions they...conference paper 2007

TNO Defensie en Veiligheid (author), Francius, M.J. (author), Piazzola, J. (author), Forget, P. (author), le Calve, O. (author), Kusmierczyk-Michulec, J. (author)Results from a quantitative model for the prediction of the sea-salt mass flux produced in the surf zone are presented in this paper. The model relates the surf zone sea salt mass flux to the amount of wave energy dissipated in the surf zone. In order to apply this aerosol emission model, a wave numerical model is required to obtain estimates...conference paper 2007

TNO Defensie en Veiligheid (author), Schoemaker, R.M. (author)Sea basing operations in coastal environments require a rapid and accurate description of the physical conditions in the region. Battlespace characterization and sensor performance assist in optimizing the efficiency and safety of operations, of which the detection of targets at low level above the sea surface is all-important. The environmental...conference paper 2007
