          <datacite:description descriptionType="Other">大気汚染は世界中で大きな問題となっている．黄砂やPM2.5などの大気エアロゾルは，人間の健康に影響を及ぼすだけでなく，視程や大気の色合いにも影響を及ぼす．大気エアロゾルを考慮したシーンのレンダリングは多々提案されているが，汚染物質の種類によって変化する視程や大気の色合いを考慮したレンダリングについては十分な研究がなされていない．本稿で提案する手法は，Polarization Optical Particle Counter（偏光光散乱式粒子計測器）による大気エアロゾルの測定データを利用して消散係数を計算し，多重散乱を考慮した大域照明を評価したうえでスペクトラルレンダリングを実行することで，実際の汚染物質の粒径分布にしたがって視程や色合いの変化を伴う遠景の再現を試みる．</datacite:description>
          <datacite:description descriptionType="Other">Air pollution is a major problem worldwide. Atmospheric aerosols such as yellow sand and PM2.5 not only affect human health but also affect the visibility and color of the atmosphere. Although many methods for rendering scenes considering atmospheric aerosols have been proposed, there has been insufficient research on rendering that takes into account changes in visibility and atmospheric color depending on the type of pollutant. The method proposed in this article calculates the dissipation coefficient using atmospheric aerosol measurement data obtained with Polarization Optical Particle Counters, evaluates global illumination considering multiple scattering, and then performs spectral rendering to reproduce distant landscapes with the visibility and color changes corresponding to the particle size distribution of pollutants.</datacite:description>
